PFAS and lithium: what EPA's national survey found

EPA tested this water for 30 substances and found 6. PFOS averaged 4.6 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 92% of the 10,307 water systems EPA tested for it.

Between July 2023 and April 2024, EPA's UCMR 5 program tested 240 samples from 2 sampling locations for 30 contaminants (29 PFAS plus lithium). 6 were detected above the reporting level in at least one sample. Averaged over a complete monitoring set, the highest sampling location for PFOS was 4.6 ppt, at or above the MCL of 4.0 ppt that applies from 2029 (highest single sample 5.4 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: yes at 8 of 8 sampling events; potential PFAS sources nearby: no at 8 of 8 sampling events; PFAS treatment in place: no PFAS treatment at 8 of 8 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 0.7 ppb, below the 15 ppb action level that triggers utility action. None of the 12 periods on record reached it.

In the most recent completed lead monitoring period, ending Dec 1, 2023, the 90th-percentile lead result at customer taps was 0.7 ppb, below the action level of 15 ppb (12 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).
