Percentage of private well water samples testing safe for Nitrate.
Why is this important?
Nitrate naturally occurs in plants and animals. Nitrate can enter groundwater from fertilizers and from animal and human waste. If the nitrate level is less than 10 parts per million (ppm) it is safe for drinking, preparing food, or showering. If the nitrate level is 10 ppm or greater, women who are or may become pregnant and babies should immediately stop using the water for drinking and preparing foods that use a lot of water like infant formula, soup, and rice. Do not boil the water because that will concentrate the nitrate as the water evaporates. If the nitrate level is 10 ppm or greater, everyone should avoid long-term use of the water for drinking and preparing foods. Everyone can use the water for showering or household chores. An alternative water source may be necessary or a water treatment system can be installed to remove the nitrate. Private wells should be tested at least once each year for nitrate because nitrate levels can change.
