Nitrite Water Test
Nitrites in the form of mineral salt are commonly found in the ground, and are often a component in road salt. The most common cause of nitrite contamination is from road salts entering the well system. Other causes of nitrite contamination may be from surface water, runoff from fertilizer use, leaching from septic systems, sewage, or erosion of natural deposits. Infants who consume water with excess levels of nitrites may become ill.
