This figure was transcribed from the utility's Consumer Confidence Report — the annual summary a utility writes about its own water — not from the underlying sampling records, which this site has not seen. That is why the basis reads unverified.

Where this ranks

This system's nitrate sits in the top 18% nationally. Systems reporting less serve about 82% of everyone on NitrateSmart's tracked supply; the other about 18% are on systems reporting the same or more. That compares what systems reported, not what comes out of any one tap.

What "Human impact likely" means

Nitrate here is low, but a little above natural background[1] — enough to suggest that fertilizer, manure, a septic system, or wastewater has reached the source. This is a statement about where the nitrate came from, not about harm.

The bands describe how strongly human activity, read from nitrate, has marked a water source — they are not a safety verdict. More on what the numbers mean and where nitrate comes from.
