Minnesota · system MN1430003 · serves 5,607 people
Placed from Minnesota's annual per-system state figures — one step further from the tap than a raw sample. The three-year range below is the annual spread.
The reading
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 reported nitrate sits in the top 22% nationally. Systems reporting less serve about 78% of everyone on NitrateSmart's tracked supply; the other about 22% 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.
Sources
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.
