Wagner, Chief Engineer-Utilities R. Wirtz, Utility Manager J. Mueller, Administrative Assistant H. Jacobs 1. Call to Order and Pledge of Allegiance Mayor Bierce called the meeting to order at 4:00 p.m. and called for everyone to stand for the Pledge of Allegiance. 2. Public Comment - Please limit your comments to two minutes. If further time for discussion is needed, please contact your District Alderperson prior to the meeting. No public comments were made. 3. Discussion and Action Regarding the Minutes 3.1 Discussion and possible action to adopt Mar 05 2026 meeting minutes. Motion was made and seconded (M.Kreiter, J. Blackwood) to approve the March 05, 2026 meeting minutes. The motion passed unanimously. 4. Storm Water Management Division 4.1 Discussion and possible action regarding the 2025 MS4 Annual Storm Water Report. Mr. Wirtz presented the annual storm water report, explaining that the city is working to finalize its TMDL (Total Maximum Daily Load) requirements by the end of summer. He noted that the agreement with the City of Brookfield water treatment facility to purchase credits will significantly help reduce the number of projects needed to meet TMDL requirements due to the efficiency of the waste water treatment plant in removing Total Suspended Solids (TSS) and phosphorus. Mr. Wirtz reported that the storm water management team conducted extensive erosion control inspections through both internal staff and consultants. The enforcement efforts included issuing five Notices of Noncompliance and eight Notices of Violations, with recommendations for fines sent to the sheriff's office resulting in tickets being issued. Most of the City's best management practices were inspected, with only two locations inaccessible due to snow. DRAFT Page 4 of 104 The report tracked salt usage at approximately 2,100 tons of salt and 3,380 gallons of brine used before the recent snow storm, with additional usage numbers to be refined for the next report. This winter proved more demanding than the previous year, requiring increased salt usage. Mr. Wirtz emphasized ongoing efforts with the highway department to better track salt application rates. Street sweeping operations totaled 2,405 lane miles of roadway swept during the year, which represents multiple passes over the city's approximately 198 lane miles of roads. The sweeping helps remove leaves and debris to prevent materials from entering the storm sewer system. Mayor Bierce inquired about the disposal of swept materials, learning that debris goes to the landfill due to metal contamination from vehicles, brake pads, and atmospheric sources. Mr. Wirtz explained that while some communities have explored metal recovery, it remains cost-prohibitive. The discussion of salt and brine application led to detailed explanations of their different uses. Pre-wetting roadways with brine before snow events helps prevent ice- pavement bonding when conditions are appropriate, while pre-wetting salt pellets as they leave trucks helps keep salt on pavement surfaces rather than bouncing off the roadways. Some counties have experimented with all-brine applications, though this may result in different service levels. Committee members discussed alternative de-icing products including beet juice, pickle brine, and cheese brine. Mr. Wirtz noted drawbacks to organic alternatives, including increased slickness on roadways, corrosiveness to vehicle components, and the trade-off of introducing organic phosphorus while trying to manage other pollutants. Ms. Wagner emphasized that the city has evolved significantly in winter maintenance practices, progressing from sand to sand-salt mixtures to straight salt to the current salt-and-brine approach. The committee discussed varying service levels across different counties and municipalities. Motion was made and seconded (J. Wamser, M. Kreiter) to adopt the 2025 MS4 Annual Storm Water Report. The motion carried unanimously. 5. Water and Sewer Division 5.1 Discussion and possible action regarding Proposals to Conduct Groundwater Well Siting Study Ms. Mueller reminded the committee that after last year's water supply alternatives analysis, which examined water provision amid radium and PFAS contamination issues and deteriorating well formations, the Common Council directed staff to explore both the possibility of diverting Great Lakes surface water and continuing with DRAFT Page 5 of 104 groundwater well options. Ms. Mueller presented proposals from two firms for well siting studies. Pat Jurcek from Intera has extensive experience with projects statewide and internationally. John Jansen from Collier Geophysics has sited most of the City's existing wells and is highly regarded in the field. Both proposals involve initial desktop studies compiling existing information including contamination sources, bedrock layers, and geophysical data to create comprehensive mapping systems. Intera's proposal totaled $41,365 while Collier's came in at $37,500. Ms. Mueller noted that Collier identified the next phase would involve on-site geophysical studies and field borings after potential well sites are identified. The immediate need is for two new wells — one to replace the collapsed radium- contaminated well and another to replace a PFAS-contaminated well. Looking forward, the city will need to replace six to eight wells over the next 50 years to meet demand projections. Ms. Wagner explained that this study will help determine whether the city can remain on groundwater within its boundaries or if it needs to look outside its borders for well sites. The study strengthens any surface water application and is essential if staying on groundwater. Mr. Blackwood asked about potential duplication of efforts if neighboring municipalities have conducted similar studies. Ms. Mueller indicated this would be identified during the phase one study, though she noted the challenges of drilling wells in other communities. The discussion touched on the western areas of the county where high-producing sandstone wells exist, though Ms. Wagner cautioned about increased PFAS risk with shallower surface wells and reduced filtration through sandstone layers. Motion was made and seconded (J. Blackwood, M. Kreiter) to recommend to the council to award the well siting study to Collier Geophysics for a cost not to exceed $37,500. The motion carried unanimously. 5.2 Discussion regarding an Excerpt-AWWA Beyond the Replacement Era: Balancing Compounding Infrastructure Needs With Household Affordability Ms. Mueller presented information from the American Water Works Association (AWWA) report to validate the challenges the city faces daily. The report highlights how the water industry has evolved beyond simply replacing failing pipes to addressing contamination issues, climate change considerations, and other complex challenges that utilities struggle to fund. Ms. Wagner emphasized that the City of Pewaukee is not alone in these struggles, with many communities advocating for federal and state assistance to prevent all DRAFT Page 6 of 104 costs from hitting ratepayers. She noted that communities nationwide are experiencing double and triple-digit rate increases during current rate case proceedings, reflecting the ongoing impacts of COVID-era increases in labor and supply chain costs that never returned to previous levels. The discussion covered affordability programs, including a COVID-era federal program that helped residents pay water bills, which ended in 2023 despite strong advocacy for its renewal. The program effectively reached severely impoverished households. When asked about local residents struggling with water bills, Ms. Mueller indicated the city has some customers who don't pay on time, with arrearages collected through the tax roll. During COVID, five to ten residents requested relief programs, with staff directing them to available veteran assistance programs. The conversation evolved into broader water system considerations, including the concept that 90 percent of treated water isn't used for consumption purposes. Ms. Mueller suggested exploring point-of-use reverse osmosis systems for drinking water while providing lower-quality water for other uses, though this would require significant regulatory changes and presents monitoring challenges. The committee discussed regional approaches and different water systems like those in Las Vegas with multiple water qualities for different uses, though these require operating multiple systems with associated costs. Mr. Blackwood suggested comparing local rates to those in water-scarce regions like Arizona and Nevada to provide perspective during rate discussions. Mayor Bierce requested that this information be presented to the Common Council given the ongoing discussions about water rates and infrastructure needs. 6. Public Comment - Please limit your comments to two minutes. If further time for discussion is needed, please contact your District Alderperson prior to the meeting. No public comments were made. 7. Adjournment Motion was made and seconded (M. Kreiter, J. Wamser) to adjourn the meeting at 4:44 p.m. The motion passed unanimously. Respectfully Submitted Magdelene Wagner Director of Public Works DRAFT Page 7 of 104 City of Pewaukee - New Agenda Item Agenda Language: Discussion and possible action regarding Well #8 PFAS Pilot Study [Mueller/Kincaid] Sub Item Agenda Language: Background Provided By: Jane E. Mueller Background: Early in our evaluation of PFAS treatment systems, one of the considerations was how the treatment system would affect the look of the Well #8 building. While working with our consulting engineers, we learned that anion exchange resin (AIX) treatment plants have a smaller footprint than the other common treatment of Granular Activated Carbon (GAC) systems. With some internal building modifications, we would be able to excavate the floor of the existing garage, creating a recessed space for the pretreatment and PFAS treatment vessels, while keeping the same east-facing view of the structure. Therefore, in early 2025, the Utility requested proposals from three companies/consultants that provide PFAS treatment system to supply pilot treatment plants so the Utility could determine the most appropriate treatment system for PFAS removal at Well #8. From May 2025 through May 2026, the Utility staff operated a PFAS removal pilot system using Lanxess TP108 media anion exchange resin (AIX) in the small-scale treatment plant. The variables evaluated included: 1) media life, 2) pretreatment requirements, 3) backwash frequency, and 4) treatment effectiveness. Well #8 has naturally occurring high levels of iron. One treatment vessel operated using only a bag filter for pretreatment for iron, while another vessel operated with an OxiPlus filtration system. Over time, the AIX media became fouled with iron despite the use of OxiPlus media for pretreatment. In October 2025, an additional column utilizing SandPlus iron-removal media was added. Initially, the SandPlus column was operated with an additional oxidant. However, in February 2026, aeration was added at the head end of the SandPlus system to allow for greater iron removal. Summary Considering all the variables evaluated, AIX treatment using Lanxess TP108 media is recommended for the full-scale PFAS treatment system at Well #8, as the media performed effectively in removing PFAS compounds. SandPlus pretreatment with inline pressure aeration was determined to be the most applicable pretreatment process because it effectively reduced iron concentrations without the use of additional Page 8 of 104 chemicals. Fiscal Impact: Estimated $2,000,000 Recommended Motion: Recommend that the Public Works Committee forward the PFAS Pilot Test Report move on to the Common Council Page 9 of 104 May 13, 2026 Jane Mueller, Utility Manager City of Pewaukee Water and Sewer jem@pewaukee.wi.us Subject: PFAS Pilot Test Report for the City of Pewaukee Dear Ms. Mueller, WaterSurplus would like to thank you for the opportunity to provide PFAS pilot testing for the City of Pewaukee.

SUMMARY A pilot study was performed at Well 8 for the City of Pewaukee. This study was designed to confirm Lanxess TP108 AIX media is suitable for PFAS removal at this location and verify state and EPA regulatory PFAS limits are met. The duration of the pilot was 361 days. In the process of the pilot, multiple variables were evaluated to determine the best full scale system configuration. This included:  Media life  Pretreatment requirements  Backwash frequency  Treatment effectiveness Based on these variables, AIX treatment using Lanxess TP108 media is recommended for use for the full-scale system at Well 8 for removal of PFAS. Table 1 provides the average raw water and treated PFAS concentrations. Two different technologies were evaluated for iron removal pretreatment which included OxiPlus75™ and SandPlus™ media. It was determined that SandPlus™ with inline pressure aeration was the most applicable pretreatment process as it effectively reduce the iron and no additional chemicals were required in this process. This will minimize the backwashing frequency required for the AIX columns. Table 1.

BACKGROUND Well water from the City of Pewaukee Well 8 was used for the pilot test for PFAS removal. The well water contains concentrations of PFOA, PFOS and PFHxS that are above the EPA regulatory limits. The well is located at W249N2173 Fox Creek Court, Pewaukee, Wisconsin. The well currently has a flowrate of 400 gpm but may increase to 500 gpm after rehabilitation. The existing wellhouse is designed to blend in with the neighborhood and looks very similar to a house. The new equipment will need to fit inside the existing garage space. Figure 1. Well House Previous sizing estimates indicated that anion exchange resin (AIX) is the preferred media due to the higher flowrate and smaller footprint compared to GAC. The Lanxess TP108 media was selected because previous studies have shown that it is successful in removing PFAS and has a longer treatment life than comparable medias. This media is NSF-61 certified for use in drinking water applications. Lanxess TP 108DW AIX resin is a 20x50 mesh, gel type polystyrene based strong base anion exchange resin. This is a one-time use absorption resin and no regeneration is performed. This media has modified functional groups to facilitate a very selective uptake of per- and polyfluoroalkyl substances (PFAS). The well water does contain 0.5 mg/L of iron so iron pretreatment may be necessary to minimize fouling and/or backwashing requirements for the AIX PFAS treatment system. The pilot testing was designed to further evaluate if iron pretreatment was necessary. 3. OBJECTIVES The test objectives of the pilot test are:  Confirm the PFAS loading capacity of the media.  Confirm the effluent PFAS concentrations are below state and EPA regulations, preferably reduced to non-detectable concentrations.  Evaluate if any fouling or plugging of the media occurs and determine if backwashing is sufficient for continued operation of the media (if needed).  Evaluate the prefiltration requirements for successful operation of the media and estimate the filter backwash frequency for a full-scale system. Page 14 of 104 Page 5 of 42 4. PILOT DESCRIPTION AND PROCEDURES The pilot system was set up to test PFAS treatment both with and without pretreatment for iron. At the start of the pilot, pretreatment for iron reduction was performed using OxiPlus75 media. The PFAS treatment that utilizes the OxiPlus75 filter system stored pretreated water after iron removal for near continuous flow of the PFAS column. The PFAS treatment column without pretreatment will only operate when the well is running (expected 6-12 hours per day). During the pilot test, an additional iron pretreatment technology was also tested which consisted of SandPlus with pressure aeration. A PFD of the pilot system is provided in the appendix. A single connection to the well system (Figure 2) was used to supply all water for the pilot system. The raw water supply connection was before any chemical injection at the well site. Figure 2. Pilot Feed Connection This was used as the source water for a booster feed pump (Figure 3) that was energized only when the well was running. A backflow preventer was installed at the outlet of the pump. After the backflow preventer, the source water was split into two different streams. One raw water stream was connected directly to the PFAS treatment system (Column 2) and did not have any pretreatment for iron removal. Figure 3. Feed pump with backflow preventer Page 15 of 104 Page 6 of 42 Due to the iron concentrations in the well water, the other raw water stream was treated for iron removal using an OxiPlus75 media filtration pilot. This pretreatment system only operated when the well was running. The OxiPlus75 pilot system was operated at a flow rate of 4.2 gpm representing a load rate of 7.86 gpm/ft2. The OxiPlus75 pilot inlet was attached to the supply pump via a flexible hose. This connection supplied both the raw water and the backwash water. A chemical feed tank on the pilot skid supplied sodium hypochlorite to the feed water. The mix flowed through a static mixer prior to the filter. The pilot unit has an automated controller to control whether the unit is in service mode or backwash mode. In service mode, water enters at the top of the filter column and flows down through the filter bed (36” depth of OxiPlus75 filter media atop a support bed of gravel). There is a basket strainer at the bottom of the tank where the treated water collects and then flows up the center tube and out. During backwash mode, the flow is reversed. The backwash flowrate is 13.5 gpm for 5 minutes. The backwash piping and finished water piping each have separate globe valves and gate valves for flow adjustment and isolation. An automated backwash was performed after 6,000 gallons of water were treated. A flow meter is present on the inlet piping to verify flow rates. Filtered water was sent to the storage tank via a flexible hose. Any additional water produced that was not used by the PFAS filtration system was sent to the drain using a designated overflow port on the tank. The backwash water was sent to the onsite drain. A pump was connected to the tank and used to supply the pretreated feed water for the PFAS system. Figure 4. OxiPlus Pilot System OxiPlus Filter OxiPlus Effluent Storage Tank Hypochlorite Feed Tank Bisulfite Feed Tank Page 16 of 104 Page 7 of 42 A picture of the PFAS pilot system is presented in Figure 5 below. The pilot has the ability to allow different sources of water to be used with the same pilot system (column 4 used OxiPlus pretreated water, column 2 used raw water). The connection from the supply source to the PFAS pilot system was made using 1” hose with cam lock fittings. This connection supplied both the raw water and the backwash water. Figure 5. PFAS Pilot System This system has four columns available to test different media, but only two of the columns were initially used during this pilot test. This system includes a filter housing with a 10-micron bag filter and pressure regulator which was used with only the raw water source for column 2. The OxiPlus pretreated water was piped directly to the column 4 inlet. Sodium bisulfite was added to the OxiPlus pretreated water to remove residual hypochlorite. Each column can be individually backwashed even when the other columns are in normal operation. For each column, there are sample taps before and after each column. The effluent from the columns is piped into a manifold and the treated water was sent to the onsite drain. In service mode, water enters at the top of the filter column and flows down through the filter bed (36” depth of Lanxess TP108 AIX media on top of a 5” support bed of anthracite). There is a screen at the bottom of the column where the treated water collects, and then flows out of the bottom to the effluent discharge line. During backwash mode, the flow is reversed using two 3-way valves. The backwash piping and finished water piping use the same diaphragm flow adjustment valve. The backwash is a manual process and was only performed if the differential pressure between the inlet and outlet of the column exceeded 10 psi differential. A flow meter is present on the inlet piping to verify flow rate to each column. A totalizer is also installed to verify the total gallons of water treated for each column. Filtered water and backwash water are piped together and are discharged Column 4 Column 2 Page 17 of 104 Page 8 of 42 to the onsite drain. The flowrates of the pilot were determined based on the anticipated flowrate and design of the full-scale system. Refer to Table 2. Table 2.

The media that was being tested was SandPlus. SandPlus is a NSF61 certified, high flow filter medium that can filter to smaller particle sizes compared to many other filter media. Previous experience with other PFAS pilots has shown this to be effective to minimize solids building up on the AIX column. The two empty columns in the PFAS skid were used for this. Column 1 was loaded to a 36” media depth with SandPlus media. Raw water (taken before the bag filter) was used for this testing. The column containing the SandPlus media was operated in a similar manner as the PFAS columns. The water entered the top of the column and flowed through the media and the flowrate was controlled by the diaphragm valve on the outlet. A tee and valve were installed at the outlet sample valve, and a portion of the treated water was sent to column 3 using a flexible hose. This was used for additional PFAS treatment using AIX resin. Any SandPlus treated water not used by AIX column 3 was sent to drain. Page 18 of 104 Page 9 of 42 Figure 6. PFAS System with SandPlus and additional TP108 Media Column After initial loading of the SandPlus media, the column was backwashed for 30 minutes for the initial backwash. The SandPlus was only backwashed if the differential pressure reached 10 psi differential or there was significant iron in the filter effluent. When needed, the SandPlus was backwashed at 1.4 gpm (16 gpm/ft2) for 8 minutes. During any backwash, the flow to the PFAS column (column 3) is stopped to avoid excess solids being sent to this column. Table 3.

PFAS – Well Water The concentration of PFAS did vary throughout the testing phase but were within the expected concentrations. PFOA, PFOS, PFHxS and the hazard index were all above the EPA regulatory limits. Both Gen X and PFNA were below detection in the untreated water during the duration of the pilot and the concentration of PFBS was low and was only a minor contributor to the hazard index. Table 4.

PFHxS Concentrations from AIX Media Column Treatment 5.3. Iron Pretreatment The initial concern was that due to iron in the water the increase of differential pressure would require frequent backwashing of the AIX media so pretreatment for iron removal was included as part of the pilot. During the pilot test, iron concentrations were monitored throughout the pilot process as it has been previously noted that iron can cause a layer to form on PFAS media that causes an increase in pressure differential. The untreated raw waste contained an average of 0.50 mg/L. The average iron concentration after each technology in the pilot is presented in Table 9. Table 9. Average Iron Concentrations Raw Water Bag Filter Effluent AIX Effluent (Column 2) OxiPlus75 Effluent SandPlus Effluent (No Aeration) SandPlus w/ Aeration Effluent Fe (Average) 0.50 mg/l 0.39 mg/L 0.16 mg/L 0.07 mg/L 0.23 mg/ 0.08 mg/L As expected, the AIX media in column 2 (only bag filter pretreatment) was removing a significant concentration of the iron in the untreated water. As presented in Figure 11 below, the concentration of iron in the effluent decreased with continued operating time. This is common with this media. The effluent from this column averaged 0.11 mg/L, indicating greater than 75% of the iron in the untreated water was being removed. Page 25 of 104 Page 16 of 42 Figure 11. Iron Concentration of Raw Water and Column 2 Effluent Page 26 of 104 Page 17 of 42 During discussions of the pilot performance, it was determined that the performance of the bag filter should also be evaluated as these initial iron removal concentrations for column 2 included the performance of the bag filter. Starting in Oct, the bag filter effluent (influent to column 2) was also measured. The bag filter was removing approximately 30% of the iron in the water but there was still a significant decrease in iron concentration in the effluent of column 2 indicating that the AIX media was removing a significant concentration of iron. Figure 12. Bag filter at end of study As presented in Figure 13 below, the OxiPlus75 filtration system was removing iron and achieving >90% iron removal and reducing iron to low concentrations. This is typical performance for this media. The first month did have elevated iron in the effluent as the backwash was not automatic at that time. A new controller was installed on the pilot unit to perform automated backwashes every 6,500 gallons. It was noted that there was still some breakthrough of iron and the backwash frequency was reduced to 6,000 gallons and was sufficient to eliminate iron breakthrough. However, there was still solids accumulation on the media which was unexpected. (This will be further discussed in the following sections.) An additional filtration media was added to evaluate if SandPlus can be used for enhanced pretreatment instead of OxiPlus75. Previous experience within WaterSurplus has shown that this media is able to remove iron and can be used for pretreatment to the AIX columns. Initially, the media was used without an oxidant being added (refer to Figure 14 for results). The media was able to reduce the iron to <0.1 mg/L. However, it was not consistent with the iron reduction. Aeration was added to enhance the iron removal. This did further reduce the iron and keep the concentration below the target of 0.1 mg/L.

Iron Concentration of Raw Water and SandPlus Effluent (influent to Column 3) Page 29 of 104 Page 20 of 42 5.4. Differential Pressure Column 4 that was receiving the OxiPlus effluent required backwash more often than column 2 that had no iron pretreatment (refer to Figure 15). Both of these columns were treating the same flowrate and had 36” of TP108 media. However, column 4 had more hours of operation as the OxiPlus effluent was stored in a tank that could be used when the well was offline. For this reason, comparing backwashing frequency based on days of testing is not a representative comparison. Figure 16 provides a comparison of gallons treated vs differential pressure. Page 30 of 104 Page 21 of 42 Figure 15. PFAS Columns Differential Pressure (Days of Operation) Page 31 of 104 Page 22 of 42 Figure 16. PFAS Columns Differential Pressure (Gallons Treated) Page 32 of 104 Page 23 of 42 When comparing the increase in differential pressure when treating up to 12,000 gallons of water per column the rate of increase was similar for both columns. Figure 17. Comparison of DP with and without OxiPlus for initial 12,000 gallons of treatment During backwash of column 4, there were visible solids that were loosened and backwashed from the column. Following a backwash, column 4 did return to near the initial differential pressure at startup indicating backwashing is sufficient to remove the solids buildup. However, the benefit of having OxiPlus75 as a pretreatment to reduce backwashing of the AIX PFAS media was limited. Page 33 of 104 Page 24 of 42 Figure 18. Solids during backwash Both the no pretreatment AIX column (column 2) and the SandPlus pretreatment column (column 3) were only operated when the well was running so both columns had the same time of operation. Column 3 with the SandPlus pretreatment generally had a lower differential pressure compared to no pretreatment (refer to Figure 19). However, when aeration was added, the column with SandPlus treatment had a significantly lower differential pressure compared to the no pretreatment column. This indicates that the SandPlus with aeration was providing beneficial pretreatment for the AIX media. Page 34 of 104 Page 25 of 42 Figure 19. Comparison of DP with and without SandPlus treatment 5.5. SDI Testing Silt density index (SDI) testing was performed during the pilot to further understand the accumulation of solids. Ideally, a 15 minute SDI of <1 is preferred. The OxiPlus effluent had a higher SDI than the untreated water even though the iron was lower concentration. This supports the hypothesis that fine particles are still present after the OxiPlus filter and are causing the pressure differential that occurs with the resin. An SDI was performed with the SandPlus media which has shown that the effluent had a lower SDI than the untreated water. This was an additional indication that it may be beneficial to reduce the backwash frequency of the AIX media. Table 10.

Filter paper from SDI testing (23Oct2025) 5.6. Additional Analytical Results A few additional parameters were monitored during the pilot test. These included TDS, chloride and arsenic. The average results before and after the AIX columns are provided in Table 11. The TDS and chloride concentrations had very little change during the study and the concentration in the water will not have a significant impact on the removal efficiency of the PFAS compounds. There was no significant change in concentration of these components after being treated by the AIX media. While the AIX media is chloride based, the absorption of PFAS and other compounds is slow so the release of chloride from the media does not change the measurable concentration in the water.

While these treatment technologies are not specifically designed for arsenic removal in this application, it is an added benefit. As discussed above, for all columns there was a decrease in iron concentration either in the media bed (no pretreatment column) or the pretreatment media. The arsenic will bind with the iron that was being removed and is filtered out. This arsenic will be removed from the treatment system along with the iron when the media is backwashed. Similar arsenic reductions are expected in the full- scale system. OxiPlus Effluent Untreated Water SandPlus Effluent Page 36 of 104 Page 27 of 42 6. DISCUSSION OF FULL-SCALE SYSTEM 6.1. System Recommendation Based on the results of pilot testing, Lanxess TP108 AIX media would meet or exceed the treatment requirements for PFAS and is recommended for the full-scale system for Well 8. Both OxiPlus75 and SandPlus were able to significantly reduce the iron concentrations. However, the OxiPlus75 still had a high SDI following treatment and did not significantly improve the time between backwashes of the AIX media but the SandPlus did show improvement in operation for both. Therefore, SandPlus with aeration is recommended as the pretreatment technology to reduce iron in the incoming water and minimize solids accumulating on the PFAS media. These systems are further discussed in the sections below. 6.2. System Sizing A lead/lag configuration is recommended for this application as this allows for one vessel to be offline for maintenance, backwashing, or media replacement without having to shut down well operation. The system is designed to be able to treat up to 500 gpm. Table 12.

AIX Media Life Due to the limited availably of water from the well, breakthrough was not achieved during the pilot. The pilot treated 67,000 bed volumes in a single column with the effluent of the column still at non detectable concentrations. Since breakthrough was not achieved, an estimate of media life was performed based on the water quality. Media life was estimated when the effluent of the lead media bed would be greater than the EPA limits (PFOA >4 ng/L, PFHxS >10 ng/L) and a media changeout in this vessel would be required. These estimates are provided in Table 14. Table 14. Estimated Media Life of Full-Scale System AIX Bed Volumes 160,000 Volume (Mgal) 190 total (95 per vessel) 6.4. Backwash Frequency The SandPlus will require periodic backwashing due to the accumulation of iron. The AIX media will need to be backwashed when initially put into service (including media changeouts) or if an increase in differential pressure of 10 psi is obtained. The backwash water volumes are presented in Table 15. Table 15. Backwash Volumes AIX System SandPlus System Media Changeout Backwash Backwash Backwash Flowrate 39 gpm 39 gpm 213 gpm Loading Rate 2 gpm/ft2 2 gpm/ft2 17 gpm/ft2 Duration 20 min 20-40 min 8 min Total Number of Vessels 2 2 3 Volume Used per Vessel 780 gal 780-1,560 gal 1,705 gal Total Volume 1,560 gal(1) 1,560-3,120 gal 5,115 gal (1) For initial system startup, this volume will be double for the AIX system It is generally recommended to have a backwash collection tank with sufficient volume to hold two backwash cycles. This would be 10,200 gallons which would accommodate backwashing for both SandPlus and the AIX system as these would not be backwashed at the same time. It is expected that the full-scale AIX resin system would require a backwash only when the differential pressure is greater than 10 psi. Based on pilot testing, this may occur every 3-6 months. The full-scale SandPlus system is expected to require a backwash every 30 hours of operation or if the differential pressure exceeds 10 psi. Page 38 of 104 Page 29 of 42 7. RECOMMENDATIONS Based on pilot test results, these are the recommendations for the full-scale system:  PFAS System o A dual 60” lead/lag vessel system (4 vessels) with Lanxess TP108 AIX media is recommended for the removal of PFAS which will meet state and EPA regulations for PFAS concentrations in drinking water. o Breakthrough of the PFAS compounds was not achieved during the pilot, but an estimate was based on other similar studies estimated that the full- scale system can treat 190 Mgal before a media changeout is needed. o The PFAS vessels will only require a backwash if the pressure differential exceeds 10 psi. It is estimated that this may occur with 3-6 months of operation. Backwashing was successful to reduce the differential pressure.  SandPlus System o A triplex 48” SandPlus filtration system with pressure aeration is recommended to minimize iron buildup in the AIX system. o The SandPlus system will require a backwash every 30 hours of operation or if the differential pressure exceeds 10 psi. 8.

Health Information Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline at (800) 426-4791. Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno -compromised people such as those with cancer undergoing chemotherapy, people who have undergone organ transplants, people with HIV/AIDS, or other immune systems disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by c ryptosporidium and other microbial contaminants are available by calling the E PA 's Safe Drinking Water Hotline at (800) 426-4791.

Educational Information The sources of drinking water, both tap water and bottled water, include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground it dissolves naturally occurring minerals and, in so me cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include:  Microbial contaminants, such as viruses and bacteria which may come from sewage treatment plants, septic systems, agricultura l livestock operations and wildlife.  Inorganic contaminants, such as salts and metals which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.  Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff and residential uses.  Organic chemical contaminants, including synthetic and volatile organic chemicals , which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff and septic systems.  Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, the EPA pr escribes regulations that limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water, which shall provide the same protection for public health. Definitions Term Definition AL Action Level: The concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a water system must follow. HA and HAL HA: Health Advisory. An estimate of acceptable drinking water levels for a chemical substance based on health effects information. HAL: Health Advisory Level is a concentration of a contaminant that, if exceeded, poses a health risk and may require a water system to post a public notice. Health Advisories are determined by the U.S. Environment Protection Agency (US EPA). Page 54 of 104 Term Definition HI HI: Hazard Index is used to assess the potential health impacts associated with mixtures of contaminants. Hazard Index guidance for a class or mixture of contaminants may be determined by the US EPA or Wisconsin Department of Health Services (WDHS). If a Health Index is exceeded, a system may be required to post a public notice. Level 1 Assessment A Level 1 assessment is a study of the water system conducted to identify potential problems and determine, if possible, why total coliform bacteria have been found in the water system. Level 2 Assessment A Level 2 assessment is a very detailed study of the water system conducted to identify potential problems and determine, if possible, why an E. coli MCL violation has occurred, why total coliform bacteria have been found in the water system, or both, on multiple occasions. MCL Maximum Contaminant Level: The highest level of contaminant allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. MCLG Maximum Contaminant Level Goal: The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. MFL million fibers per liter MRDL Maximum Residual Disinfectant Level: The highest level of a disinfectant allowed in drinking water. There is convincing evidence that the addition of a disinfectant is necessary to control microbial contaminants. MRDLG Maximum Residual Disinfectant Level Goal: The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of using disinfectants to control microbial contaminants. mrem/year Millirems per year (a measure of radiation absorbed by the body) NTU Nephelometric Turbidity Units pCi/l Picocuries per liter (a measure of radioactivity) ppm Parts per million, or milligrams per liter (mg/l) ppb Parts per billion, or micrograms per liter (ug/l) ppt Parts per trillion, or nanograms per liter ppq Parts per quadrillion, or picograms per liter PHGS Public Health Groundwater Standards are found in NR 140 Groundwater Quality. The concentration of a contaminant that, if exceeded, poses a health risk and may require a system to post a public notice. RPHGS Recommended Public Health Groundwater Standards. Groundwater standards proposed by the WDHS. The concentration of a contaminant that, if exceeded, poses a health risk and may require a system to post a public notice. SMCL Secondary drinking water standards, or Secondary Maximum Contaminant Levels (SMCLs), are established for contaminants that affect the taste, odor, or appearance of the drinking water. SMCLs do not represent health standards. TCR Total Coliform Rule TT Treatment Technique: A required process intended to reduce the level of contaminant in drinking water. Detected Contaminants Your water was tested for many contaminants last year. We are allowed to monitor some contaminants less frequently than once a year. The following tables list only those contaminants that were detected in your water. If a contaminant was detected last year, it will appear in the following tables without a sample date. If a contaminant was not monitored last year, but was detected within the last five years, it will appear in the tables below along with the sample date.

The following table lists PFAS contaminants which were detected in your water and that have a R ecommended Public Health Groundwater Standard (RPHGS) or Health Advisory Level (HAL). There are no violations for detections of contaminants that exceed the RPHGS or HAL. The RPHGS are levels at which concentrations of the contaminant presen t a health risk and are based on guidance provided by the W isconsin Department of Health Services (WDHS). Note: The recommended health-based levels in the table below were in effect in 2024. These levels were revised by WDHS in 2025. They can be found here: https://www.dhs.wisconsin.gov/water/gws.htm. Typical Source of Contaminant Drinking water is one way that people can be exposed to PFAS. In Wisconsin, two-thirds of people use groundwater as their drinking water source. PFAS can get in groundwater from places that make or use PFAS and release from consumer products in landfills.

The purpose of unregulated contaminant monitoring is to assist the EPA in determining the occurrence of unregulated contaminants in drinking water and whether future regulation is warranted. The EPA required us to participate in this monitoring. Within the last 12 months we conducted Unregulated Contaminant Monitoring in accordance with US EPA rules. We are required to inform you of this sampling. We are only required to include results showing detections in this report; however, if you would like a copy of all results, please contact our office at (262) 691-0804. Page 56 of 104 Health Effects for any Contaminants with MCL Violations/Action Level Exceedances/SMCL Exceedances/PHGS or HAL Exceedances Contaminant Health Effects GROSS ALPHA, EXCL. R&U Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some people who drink water containing alpha emitters in excess of the MCL over many years may have an increased risk of developing cancer. PFHXS Scientists are still learning about the health effects that various PFAS can have on the body. To date, studies among people have shown that high levels of certain PFAS can increase cholesterol levels, decrease antibody levels in response to vaccines, and decrease fertility in women. People can reduce their risk of health effects by reducing their exposure to PFAS. PFOA AND PFOS TOTAL Scientists are still learning about the health effects that various PFAS can have on the body. To date, studies among people have shown that high levels of certain PFAS can increase cholesterol levels, decrease antibody levels in response to vaccines, and decrease fertility in women. People can reduce their risk of health effects by reducing their exposure to PFAS. PFOS Scientists are still learning about the health effects that various PFAS can have on the body. To date, studies among people have shown that high levels of certain PFAS can increase cholesterol levels, decrease antibody levels in response to vaccines, and decrease fertility in women. People can reduce their risk of health effects by reducing their exposure to PFAS. RADIUM (226 + 228) Some people who drink water containing radium 226 or 228 in excess of the MCL over many years may have an increased risk of developing cancer. Additional Health Information While your drinking water meets the US EPA's standard for arsenic, it does contain low levels of arsenic. The US EPA's standard balances the current understanding of arsenic's possible health effects against the costs of removing arsenic from drinking water. The US EPA continues to research the health effects of low levels of arsenic, which is a mineral known to cause cancer in humans at high concentrations and is linked to other health effects, such as skin damage and circulatory problems. Lead can cause serious health problems, especially pregnant women and young children. Lead in drinking water primarily comes from materials and components associated with service lines and home plumbing. The City of Pewaukee Water & Sewer Utility is responsible for providing high-quality drinking water and removing lead pipes, but cannot control the variety of materials used in plumbing components in your home. You share the responsibility for protecting yourself and your family from the lead in your home plumbing. You can do this by identifying and removing lead materials within your home plumbing and taking steps to reduce your family’s risk. Before drinking tap water, flush your pipes for several minutes by running your tap, taking a shower, doing laundry, or a load of dishes. You can also use a filter certified by an American National Standards Institute- accredited certifier to reduce lead in drinking water. If you are concerned about lead in your water and wish to have your water tested, contact Jane Mueller at the City of Pewaukee Water & Sewer Utility at (262) 691-0804. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at: https://www.epa.gov/safewater/lead. Additional Information on Service Line Materials We were required to develop an initial inventory of service lines connected to our distribution system by October 16, 2024, and to make the inventory publicly accessible. You can access the service line inventory on the City of Pewaukee website at: https://portal.laserfiche.com/j9152/forms/pipeinventory. (Please type your address using this example: W240N3065 PEWAUKEE RD). Corrective Actions Taken The City of Pewaukee will be constructing a water main loop to facilitate the abandonment of Well #5, which is contaminated with radionuclides, including Gross Alpha and Radium. The City has recently completed a pilot treatment study for PFAS removal at Well #8. The building and treatment plant design is currently underway. Construction of both projects is anticipated to begin in late 2026 or early 2027. Once construction begins, the water treatme nt plant and water main loop projects are expected to take approximately 18 months to two years to complete.

Page 89 of 104 CITY OF PEWAUKEE CHAPTER 300 – SANITARY SEWER SERVICE ORDINANCE April 20, 2025 17 § 300-16 – Sewer Service Charges and Reserve Capacity Assessment A. Basis for Sewer Service Charges - The sewer service charge imposed under this section shall generate sufficient revenues to pay the total operation and maintenance costs necessary to the proper operation and maintenance (including replacement) of the Sewer System. Such system of sewer service charges shall maintain the proportional distribution of operation and maintenance costs among user classes. B. Sewer Service Charge (1) A Sewer Service Charge is hereby imposed upon each building or premise (user) served by the Sewer System or otherwise discharging sewage, including non-domestic and industrial wastes, into the system. The annual Sewer Service Charge shall be the sum of the following components, rounded to the nearest 10th of a dollar when computed on a quarterly basis: (a) One Administrative Component; (b) The product of the Operation and Maintenance Component times the number of residential equivalent connections assigned to a user; and (c) The product of the Debt Service Component times the number of residential equivalent connections assigned to the user. (2) The Administrative Component shall be the product of 50% of the Utility’s budgeted administration costs divided by the base number of sewer users. (3) The Operation and Maintenance Component shall be the product of the budgeted sewer system operating and maintenance costs divided by the base number of residential equivalent connections. Depreciation expense shall be included in the Operation and Maintenance Component of the Sewer Service Charge. The depreciation expense included in the Utility’s budget for operation and maintenance shall be computed on a basis consistent with generally accepted accounting principles. At a minimum, depreciation included in the Operation and Maintenance Component of the Sewer Service Charge shall equal the yearly replacement costs as defined by Wis. Admin.

Page 90 of 104 CITY OF PEWAUKEE CHAPTER 300 – SANITARY SEWER SERVICE ORDINANCE April 20, 2025 18 (5) The Debt Service Component is intended to accumulate, by the end of each calendar year, funds sufficient to meet the subsequent year's debt service needs. The Utility has established a Reserve Capacity Assessment (RCA) to finance, among other projects, the costs of new, upgraded, a nd existing capacity in the Fox River Water Pollution Control Center. Any and all funds collected through the RCA may be used to offset the Debt Service Component of the Sewer Service Charge. The Common Council shall determine, in conjunction with the approval of the annual Sewer Service Charge, the amount, if any, of accumulated RCA funds to be used to offset the Debt Service Component of the Sewer Service Charge. (6) The Base Number of Residential Equivalent Units shall be the number of residential equivalent connections serviced by the Utility as of the last day of the preceding fiscal year. (7) The Base Number of Sewer Users shall be the number of sewer users serviced by the Utility as of the last day of the preceding fiscal year. C.

Page 100 of 104 City of Pewaukee - New Agenda Item Agenda Language: Discussion and possible action regarding Mandatory Sewer Connections on Various Assessment Districts [Wagner/Mueller] Sub Item Agenda Language: Background Provided By: Magdelene Wagner Background: The City has several assessment districts in which the 15-year mandatory connection to the municipal sanitary sewer system has expired, is due to expire, or will expire in the near future. There are a number of properties within these assessment districts that have not yet connected. The impacted areas include: Rolling Ridge Subdivision Arrowhead Trails Subdivision Green Road Duplainville Road Still River/Bluemound Corridor Valleyview Sunnyridge Property owners have 15 years from the date of the final resolution to connect to the municipal sanitary sewer system and abandon their existing private system. This requirement was established by the City as its policy and has been included in final resolutions since the early 2000s. All resolutions were mailed to the affected property owners at the time the assessments were levied. If connection is not made in accordance with our ordinance, a standby change of 150% of the quarterly sewer charge will be sent to each property owner on their quarterly utility bill. The current quarterly sewer rate is $141. Therefore, a quarterly standby charge of $211.50 will be added to the utility bill of any property that has not connected by the applicable deadline. When sanitary sewer is extended into an area, the City typically installs the sewer main and a lateral to the property line. Most affected properties will be able to connect to this lateral. The Bluemound/Still River area is an exception because it was constructed as a developer-financed project and they were not required by the Common Council to install the full laterals. All properties in this area have a wye connection installed at the sewer main, but only a handful of property owners opted for the optional lateral to be installed at the time of the sewer installation. Most properties in this area will need to install the Page 101 of 104 entire lateral from the building to the sewer main. It should be noted that properties along Bluemound Road (CTH JJ) will be required to obtain a permit from Waukesha County because work will occur within the County right- of-way to make the sewer connection. All remaining properties will be required to obtain the City's right-of-way permit. The property owners will need to pay a private plumber to connect the system, abandon their existing private system, obtain any required permits, and pay reserve capacity assessments (RCA) and/or interceptor capacity assessments (ICA). Costs will vary depending on the area in which they are located and each individual connection scenario. Many of the special assessments should be paid in full at the 15-year mandatory connection time. Staff would like to send notices to the affected property owners and provide one year from the date of the notice to connect, which will exceed the deadline to connect for a few of the assessment districts. We understand that many of these residents will have likely forgotten, or are not the original owners of the property, and desire to give them some time to make these connections and plan for the expenses. After one year from this notice, the standby charge would be enacted for each property. Fiscal Impact: RCA = $3,767 Waukesha Connection = varies by property size Bluemound ICA = $888.08 Green Road ICA - $7,234 City ROW permit = $75 plus $1,000 1 yr. deposit, $10,000 deposit if in pavement County Permit = $410, estimated Plumbing Permits = $140, estimated Plumbing Costs = varies for each property Recommended Motion: Public Works Committee recommends that the Council allow affected residents one year to connect from the date of the City's reminder notice to the residents, or the date of the resolution, whichever is later, and if connection is not made by the deadline, to enact the 150% quarterly sewer charge. Page 102 of 104 City of Pewaukee - New Agenda Item Agenda Language: Discussion and possible action regarding whether to continue battery recycling at the DPW Recycling Center. [Stevens] Sub Item Agenda Language: Background Provided By: Magdelene Wagner/Matthew Stevens Background: The City of Pewaukee currently accepts used batteries for recycling at the DPW Recycling Center. However, staff is recommending discontinuing this service for the following reasons: 1. It takes approximately 1.5 years to collect enough batteries to fill a recycling bin and warrant a trip to the recycling facility. 2. Each full bin generates only approximately $200 in recycling revenue. 3. Due to the long collection period, contamination is a frequent occurrence. Contamination issues include leaking batteries, the disposal of improper battery types, and water contamination from rain and snow melt mixing in. Staff is spending time in a caustic environment to correct these issues. 4. The storage at the recycle yard needs to be updated to meet current Wisconsin Department of Natural Resources standards including containment structure and protection from the elements. 5. It is very simple to recycle your old battery when you replace it. Most businesses that sell batteries also accept used batteries for recycling, and in many cases, provide a credit or rebate when the used battery is returned. This is a more efficient method of proper battery disposal. Given the low usage, minimal financial return, and inefficiency of the current collection program, staff recommends discontinuing battery recycling services at the DPW Recycling Center. Fiscal Impact: The City will lose approximately $200 every 1.5 years if battery collection services are discontinued. However, eliminating this program will also remove staff exposure to caustic materials while reducing the labor costs associated with cleaning up contamination. Recommended Motion: Public Works Committee recommends to the Common Council to eliminate battery Page 103 of 104 recycling at the DPW Recycling Center. Page 104 of 104
