Nitrate and nitrite

Aurora City - Cleveland PWS

NOTE: Aurora City - Cleveland PWS purchases water from Cleveland Public Water System which is required to test for nitrate and nitrite. Sample information shown below was taken by Cleveland 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.
