Nitrite

Fort Bend County Municipal Utility District 121

NOTE: Fort Bend County Municipal Utility District 121 purchases water from City of Richmond which is required to test for nitrite. Sample information shown below was taken by City of Richmond.

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.
