New Mexico · system NM3500826 · serves 6,775 people · purchased water
This system purchases its water; the band reflects the supplier's most recent reported result within a rolling three-year window. The three-year range below is the supplier's, not this system's own sampling. The water comes from Buckman Regional Water Treatment Plant (NM3502826) and Santa Fe Water System (City of) (NM3505126).
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
The water this system purchases 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.

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.
