A legal limit is an enforceable standard, set by the EPA under the Safe Drinking Water Act. Limits weigh health research together with the cost and feasibility of treatment. A health guideline is published by public-health sources and based on health research alone. A utility can meet every legal limit and still be above a published health guideline.

The score starts at 100. It goes down 8 for each contaminant above a cited health guideline whose source states a cancer basis, 5 for each other contaminant above its cited guideline, 5 for each of PFOA and PFOS averaging above the 4.0 ppt limit in EPA's 2024 PFAS rule, 10 for each contaminant whose average of all samples is above EPA's legal limit (instead of its guideline step), and 1 for each contaminant with a cited cancer-based guideline that is detected below it. Only guidelines with a cited document count. The lowest score is 5. Higher is better.

Our systems aren't certified for PFAS.
EPA's 2024 rule sets a limit of 4.0 parts per trillion each for PFOA and PFOS; water systems must meet it by April 2029. In May 2026 EPA proposed allowing extensions to April 2031.
The level shown is the average of all of the utility's results in the years shown, with results below EPA's reporting level counted as zero. The highest single result and the number of samples in which it was detected are shown with each level. Each of these averaged above 4.0 ppt across all of the utility's samples, with results below the reporting level counted as zero. EPA judges compliance on a running annual average at each sampling point, so our combined average is a guide, not a compliance result. Under EPA's 2024 PFAS rule, water systems must meet the PFOA and PFOS limits (4.0 ppt each) by April 2029; in May 2026 EPA proposed allowing extensions to April 2031. Results before then are monitoring data, not violations.
Public data from EPA UCMR 5, 2023–2025. It isn't a test of your tap, and your water can differ. Last checked against the Federal Register: October 25, 2026.
0 means every sample was below EPA's UCMR 5 minimum reporting level (4 ppt for PFOA and PFOS); it does not mean none is present. Averages count those samples as 0, as on our utility pages.
