UTILITIES COMMISSION MEETING <br />TO: FROM: <br />ERMU Commission Dave Ninow – Water Superintendent <br />MEETING DATE: AGENDA ITEM NUMBER: <br />March11, 2025 6.1h <br />SUBJECT: <br />Staff Update <br />ACTION REQUESTED: <br />None <br />DISCUSSION: <br />Delivered a water meter, installed a Smart Point module, and took curb stop ties for 4 <br />new water services. <br />Completed 20BACTI/Total Chlorine Residual Samples <br />o All confirmednegative for Coliform Bacteria <br />o Bacteriological/Disinfectant Residual Monthly Report submitted to the MDH <br /> Completed 19 routine fluoride samples <br />o All samples met MDH standards <br />o Submitted MDH Fluoride Report <br />o Completed one MDH validation fluoride sample <br /> Submitted Discharge Monitoring Report (DMR) for the diesel generation plant to the <br />Minnesota Pollution Control Agency. <br /> Submitted Tier II Annual Reports to the Department of Homeland Security for the diesel <br />generation plant and all the water treatment plants. <br /> The Safe Drinking Water Act (SDWA) mandates the EPA to issue a list of unregulated <br />contaminants to be monitored by public water systems (PWS) every five years. The fifth <br />Unregulated Contaminant Monitoring Rule (UCMR 5), published in 2021, requires <br />sample collection for 30 chemical contaminants between 2023 and 2025. UCMR 5 aims <br />to improve the understanding of the occurrence and levels of 29 per- and <br />polyfluoroalkyl substances (PFAS) and lithium in the nation's drinking water systems. In <br />August 2024, water samples were collected from each Elk River municipal well for <br />UCMR 5 testing. We have received the results, and we are pleased to report that no <br />contaminants were detected in any of these samples. <br /> The repair of the 12" water main stub on Polk Street was successfully completed on <br />Monday, February 24. Upon investigation, it appears that a deteriorated coupling nut, <br />which connected the threaded rod holding the pipe plug in place, failed and caused the <br />leak. The plug was reinstalled with new hardware and reinforced with concrete blocking <br />to help it remain in place. <br /> The water operators have spent much of their time performing annual preventive <br />maintenance on the water treatment plants. <br />______________________________________________________________________________ <br />Page 1 of 2 <br />151 <br /> <br />
