A single reading is not a complete account of what a household drinks, so the three-year range and the number of tests behind it are shown too — a reading backed by many tests over three years is a fuller picture than one from a single sample.

Where this ranks

This system's nitrate sits in the top 12% nationally. Systems reporting less serve about 88% of everyone on NitrateSmart's tracked supply; the other about 12% are on systems reporting the same or more. That compares what systems reported, not what comes out of any one tap.

What "Human impact clear" means

Above 3 mg/L, human activity is the leading explanation for the nitrate in this system's water[1]. It is still a statement about the source, not a health verdict — the level is well below the federal limit.

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.
