Nitrate + Nitrite as N Analysis
All well owners are encouraged to test their water yearly for nitrates. High levels of nitrates may indicate a failing septic system or contamination from animal herds, fertilizers, or landfills. The Nitrate + Nitrite test is a good indicator of overall water quality. Using Federal regulations under the Safe Drinking Water Act (40 CFR 141.23 (a) (4) (i)) as a guideline, the maximum contaminant level (MCL) for Nitrate as Nitrogen is 10.0 mg/L (ppm) and for Nitrite as Nitrogen is 1.0 mg/L (ppm). The health significance of nitrate above these levels applies to pregnant women, and infants below the age of six months. The major health effect associated with these levels is methemoglobinemia, also known as “blue-baby syndrome”.

Do not rinse the sample container or discard the acid preservation disk! The filter disk is saturated with 50% sulfuric acid (see precautions) and is used to preserve the sample for the analysis of total nitrate/nitrite. Flush the sample tap for five (5) minutes prior to collecting the sample. Reduce the flow of the water and fill the sample container to the shoulder of the bottle. Replace and tighten the cap to prevent sample leaking. Do not take the filter paper out. Complete the analysis request form.
