Nitrite

Windmill Ranch Subdivision

NOTE: Windmill Ranch Subdivision purchases water from Clwsc Canyon Lake Shores which is required to test for nitrite. Sample information shown below was taken by Clwsc Canyon Lake Shores.

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.

The legal limit for nitrite, established in 1991, was based on the rate of conversion of ingested nitrate into nitrite in adults. This limit may not fully protect against the risk of cancer due to nitrite exposure.
