Nitrite

Vista Oaks Municipal Utility District

NOTE: Vista Oaks Municipal Utility District purchases water from City of Round Rock which is required to test for nitrite. Sample information shown below was taken by City of Round Rock.

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.
