Plain English

01What this means for you

Very low PFAS concentrations were detected — well below the EPA's Maximum Contaminant Level. For most healthy adults, this represents a minimal incremental risk from drinking water. The most proportionate response is to note the result and check your utility's Consumer Confidence Report again next year. If you have specific health concerns or vulnerable household members, speaking with your doctor and optionally installing a certified point-of-use filter is a reasonable step.

Detection threshold (MRL)
~1.5–2 ppt

Values shown are the highest single-sample concentration measured at entry points to the distribution system. Results reflect water quality at the treatment plant — aging pipes, building plumbing, and on-site storage can affect what actually reaches your tap. "Not detected" means below the MRL, not literally zero.
