TL;DR
A nitrate test is a laboratory analysis of well water that measures nitrate concentration against the EPA limit of 10 milligrams per liter, the threshold protecting infants from methemoglobinemia, or blue baby syndrome. Contamination typically tracks fertilizer, manure, or septic leachate moving through groundwater, so wells near farmland or aging drainfields warrant annual sampling.
What it means
A nitrate test is a laboratory analysis of well water that measures nitrate concentration against the EPA limit of 10 milligrams per liter, the threshold protecting infants from methemoglobinemia, or blue baby syndrome. Contamination typically tracks fertilizer, manure, or septic leachate moving through groundwater, so wells near farmland or aging drainfields warrant annual sampling. Boiling concentrates rather than removes it; treatment requires reverse osmosis, ion exchange, or distillation.
