| Assistance Type: | OTHER WATER QUALITY - PFAS detection | ||
| Reasons: | Other |
||
| Details: | PFAS sampling conducted as part of the fifth round of the Unregulated Contaminant Monitoring Rule (UCMR5) showed PFOS at 5.7 ppt and PFHxS at 4 ppt at entry point F (EP-F) Spicer Well for a sample collected on 5/16/23. The result exceeds EPA's non-regulatory lifetime health advisory level for PFOS of 0.02 ppt. When results show the presence of PFAS in drinking water above an EPA HAL, EPA recommends public water systems take steps to assess contamination, inform customers, and limit exposure. 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 to examine steps to limit exposure, and information on BIL-Emerging Contaminant funding available to address the contaminant. Update 5/20/24: additional UCMR5 PFAS results showed PFOS at 6.8 ppt and PFHxS at 7.4 ppt at entry point F (EP-F) Spicer Well for a sample collected on 1/30/24, and PFOS at 5 ppt at entry point A (EP-A) Firehouse Well for a sample collected on 1/30/24. | ||
