| Details: | PFAS sampling conducted as part of the OHA PFAS Sampling Project showed PFOA 5.86 ppt, PFHxS 3.50 ppt, PFHpA 7.35 ppt, PFHxA 17.8 ppt, PFPeA 21.3 ppt, 6:2FTS 69.9 ppt at entry point A (EP-A) for Well #3 for samples collected on 1/15/26. Although compliance with the MCLs is not yet required, these results indicate that DEER CREEK ESTATES may eventually exceed the MCLs for PFOA. Compliance will be based on a running annual average (RAA). If compliance monitoring beginning April 2027 shows the RAA exceeds the MCLs, the system will need to take corrective action to comply with the MCLs by April 2029. A letter was mailed and emailed to the water system on 4/22/26 which included information on how the results compare to the new PFAS MCLs, PFAS rule initial monitoring requirements, and information on Emerging Contaminant funding available to address PFAS. | ||
