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 3% nationally. Systems reporting less serve about 97% of everyone on NitrateSmart's tracked supply; the other about 3% are on systems reporting the same or more. That compares what systems reported, not what comes out of any one tap.

What "Health-study range" means

Two long-term studies of Iowa women reported higher cancer rates among people whose drinking water stayed above 5 mg/L as N for years[1][2] — thyroid cancer where the supply ran above that level for more than five years, bladder cancer where it did for four years or more — still below the federal limit of 10. Both are observational: they find associations, not proven cause, and the difference for any one person is small. In both, concentration alone fell short of significance and the years spent above 5 reached it, so 5 mg/L as N is a level that matters when it persists. Associations are also reported at lower levels; this band marks the level those two studies used. Whether this system has held this level for years is not something the three-year window below can show, and this page does not claim it.

If there is a pregnancy or an infant under about six months in the household, this is the circumstance the research concentrates on. It is worth a conversation with a clinician, who can weigh this number against everything else.

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.
