Nitrate and nitrite

Warren County Socialville PWS

NOTE: Warren County Socialville PWS purchases water from Cincinnati Public Water System which is required to test for nitrate and nitrite. Sample information shown below was taken by Cincinnati Public Water System.

Nitrate and nitrite enter water from fertilizer runoff, septic tanks and urban runoff. These contaminants can cause oxygen deprivation for infants and increase the risk of cancer. Nitrite is significantly more toxic than nitrate. Click here to read more about nitrate.
