PFAS and lithium: what EPA's national survey found

EPA tested this water for 30 substances and found none of them at levels its laboratories can measure.

Between June 2023 and December 2023, EPA's UCMR 5 program tested 120 samples from 2 sampling locations for 30 contaminants (29 PFAS plus lithium). None were found above their minimum reporting levels.

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: yes at 4 of 4 sampling events; potential PFAS sources nearby: no at 4 of 4 sampling events; PFAS treatment in place: no PFAS treatment at 4 of 4 sampling events.

Lead at customer taps

In the latest completed monitoring period, ending Dec 1, 2023, 9 in 10 sampled homes had lead at or below 1.2 ppb, below the 15 ppb action level that triggers utility action. The action level has been reached in 3 of the 23 periods on record.

In the most recent completed lead monitoring period, ending Dec 1, 2023, the 90th-percentile lead result at customer taps was 1.2 ppb, below the action level of 15 ppb; 3 of the 23 monitoring periods on record reached 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 36 violations since Sep 3, 2016. 1 is health-based, meaning a contaminant or treatment rule was not met. The other 35 concern missed monitoring, reporting or public notices. 1 is still open.

EPA's SDWIS database lists 36 violations recorded since Sep 3, 2016: 1 health-based (a contaminant above its maximum contaminant level, a disinfectant above its maximum residual level, or a required treatment technique not met), 33 for monitoring or reporting, 2 other (public notification or consumer confidence report requirements); 1 is not yet resolved.

Sanitary surveys and site visits

Most recent state inspection: Jul 19, 2023 (sanitary survey); 2 visits since Sep 3, 2021.
