High water nitrate and nitrite content may indicate that groundwater in the area is contaminated. Nitrate and Nitrite find their way into drinking water from farm fertilizer, industrial and biological waste, and naturally forming mineral deposits.
Why test the water nitrate and nitrite concentration?
Nitrate and nitrite can be accessed into drinking water from farm fertilizers, mallow waste water or natural mineral deposits. Their occurrence can often also be a sign of other pollutants that spoil the quality of water. Nitrate (NO3-N) levels above 10ppm are linked to “blue baby syndrome” in infants. The STM sets the limit for Nitrate (NO3-N) under 50ppm; the limit for Nitrite (NO2-N) is 0,5 ppm. 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 ppm and for Nitrite (NO2) 3 ppm.
Nitrate and nitrite test detects:
- Nitrate (N): 0,0,5, 2,0, 5, 10, 20,50 ppm (mg/L)
- Nitrite (N): 0.0.15, 0.3, 1.0, 1.5, 3.0, 10.0 ppm (mg/L)
- Nitrate (NO3): 0,2, 10, 20, 50, 100, 200 ppm (mg/L)
- Nitrite (NO2): 0.0.5, 1, 3, 5, 10.30 ppm (mg/L)
How to perform a test:
- Remove the test strip from the foil package
- Dip the test strip (do not move) for 2 seconds in the water sample
- Lift the strip from the water sample and place it horizontally (see picture) and wait 1 minute before reading the result
- Compare the color of the test pads with the color chart on the package. The result is readable for 1 minute. Dry the colour chart of the package gently if it is wet.
Package includes 30 individually packaged tests
