Nitrite

Southern Madison Utilities LLC

NOTE: Southern Madison Utilities LLC purchases water from Citizens Water - Indianapolis which is required to test for nitrite. Sample information shown below was taken by Citizens Water - Indianapolis.

Nitrite, closely related to the fertilizer chemical nitrate, comes from urban runoff and from fertilizer applied to agricultural lands to pollute drinking water. Nitrite is significantly more toxic than nitrate. Excessive nitrite in water can cause oxygen deprivation in infants and increase the risk of cancer.
