Nitrite

Holly Hills Mutual Water Company

NOTE: Holly Hills Mutual Water Company purchases water from Normco Water Company which is required to test for nitrite. Sample information shown below was taken by Normco Water Company.

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.
