PFAS and lithium: what EPA's national survey found

EPA tested this water for 30 substances and found 9. PFOA averaged 12.3 ppt where EPA's limit is 4.0 ppt, and PFOS averaged 29.0 ppt where EPA's limit is 4.0 ppt. EPA's limit applies to a running yearly average and is enforced from 2029. That PFOS result is higher than 99.6% of the 10,307 water systems EPA tested for it.

Between March 2023 and September 2023, EPA's UCMR 5 program tested 60 samples from 1 sampling location for 30 contaminants (29 PFAS plus lithium). 9 were detected above the reporting level in at least one sample. Averaged over a complete monitoring set, the highest sampling location for PFOA was 12.3 ppt, at or above the MCL of 4.0 ppt that applies from 2029 (highest single sample 14.4 ppt). Averaged over a complete monitoring set, the highest sampling location for PFOS was 29.0 ppt, at or above the MCL of 4.0 ppt that applies from 2029 (highest single sample 34.7 ppt).

Sampling-point average: mean of a location's two (ground water) or four (surface water) UCMR 5 results with non-detects counted as zero, EPA's method for comparing UCMR 5 data to the PFAS MCLs. EPA rounds to the reference value's significant digits before deciding whether an average is "greater than" an MCL (PFOA/PFOS averages count as above 4.0 ng/L only from 4.05 ng/L; lithium results count as above the 10 ppb reference only from 15 ppb). This site does not apply that rounding: "at or above" here means the measured value is numerically at or above the reference.

Utility-reported context (UCMR 5 questionnaire, aggregated across sampling events): PFAS previously found at this system: not known at 1 of 2 sampling events, no at 1 of 2 sampling events; potential PFAS sources nearby: no at 2 of 2 sampling events.

Lead at customer taps

In the latest completed monitoring period, ending Dec 1, 2024, 9 in 10 sampled homes had lead at or below 0.6 ppb, below the 15 ppb action level that triggers utility action. None of the 18 periods on record reached it.

In the most recent completed lead monitoring period, ending Dec 1, 2024, the 90th-percentile lead result at customer taps was 0.6 ppb, below the action level of 15 ppb (18 monitoring periods on record, none at the action level). The 90th percentile is the value that 9 in 10 sampled homes were at or below. Values are in parts per billion (ppb).

Drinking water violations since Sep 3, 2016

EPA lists 47 violations since Sep 3, 2016. 5 are health-based, meaning a contaminant or treatment rule was not met. The other 42 concern missed monitoring, reporting or public notices. 4 are still open.

EPA's SDWIS database lists 47 violations recorded since Sep 3, 2016: 5 health-based (a contaminant above its maximum contaminant level, a disinfectant above its maximum residual level, or a required treatment technique not met), 41 for monitoring or reporting, 1 other (public notification or consumer confidence report requirements); 4 are not yet resolved.

Sanitary surveys and site visits

Most recent state inspection: Mar 14, 2024 (sanitary survey); 1 visit since Sep 3, 2021.
