| Details: | PFAS sampling conducted as part of the fifth round of the Unregulated Contaminant Monitoring Rule (UCMR5) showed PFBS at 3.2 ppt at entry point A (EP-A) for South Wellfield and PFBS at 3.2 ppt at entry point B (EP-B) for Polk St/River Drive Wellfield in samples collected 5/16/23. These results are below EPA's non-regulatory lifetime health advisory level for PFBS of 2000 ppt. A letter was mailed to the water system on 8/31/23 which included information on how the results compare to state/federal health advisory levels and proposed regulations, requirements to notify customers of availability of results and report detections in the annual consumer confidence report to customers, recommendations to conduct additional PFAS monitoring using an accredited lab, and information on BIL-Emerging Contaminant funding available to address the contaminant. Update 5/20/24: additional UCMR5 PFAS results showed PFBS at 3.4 ppt at entry point A (EP-A) for South Wellfield and PFBS at 3.1 ppt at entry point B (EP-B) for Polk St/River Drive Wellfield in samples collected 11/20/23. | ||
