Recommended for targeted, high-resolution testing of nitrate in drinking water.

Nitrate is a common groundwater contaminant, particularly in rural areas and those near areas with heavy agricultural activity.

Fertilizers, septic systems, and manure-related operations are the most common sources contributing to nitrate contamination in drinking water supplies. The US government regulates nitrate in drinking water because high nitrates can cause methemoglobinemia, or "blue baby" disease. Subsequently, nitrate testing is recommended for pregnant women and households with newborn babies.
