The WaterWorks™ Nitrate / Nitrite test strips for water quality testing are the ideal solution when portable, reliable results matter. Whether testing well water or using them as a routine home testing solution, these strips are the best choice. Designed to be safe, no technical training is required to achieve results. The test reports results as Nitrogen (N).

Why test for Nitrate and Nitrite?

This test detects Nitrate and Nitrite measured as Nitrogen (NO3-N & NO2-N). Nitrate and Nitrite find their way into drinking water from farm fertilizer, industrial and biological waste, and naturally forming mineral deposits. Their presence can often be a sign of other pollutants in the water. Nitrate (NO3-N) levels above 10ppm are linked to “blue baby syndrome” in infants. The EPA sets the limit for Nitrate (NO3-N) at 10ppm; the limit for Nitrite (NO2-N) is 1ppm. Nitrite (NO2-N) levels above the EPA limit can be an indicator that bacteria are present. The WHO guideline value for Nitrate (NO3) is 50 mg/L and for Nitrite (NO2) 3mg/L.
