Nitrite

Menomonee Falls WW - Surface Water

NOTE: Menomonee Falls WW - Surface Water purchases water from Milwaukee Waterworks which is required to test for nitrite. Sample information shown below was taken by Milwaukee Waterworks.

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.

EPA Maximum Contaminant
Level (MCL) 1 ppm

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.
