Nitrite

Denton County Fresh Water Supply District 8-b Paloma

NOTE: Denton County Fresh Water Supply District 8-b Paloma purchases water from Utrwd Regional Water Treatment Plant which is required to test for nitrite. Sample information shown below was taken by Utrwd Regional Water Treatment Plant.

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.
