Because private wells are not regulated and are also at risk for nitrate contamination, this program is intended to help residents who may be unknowingly consuming water with unsafe levels of nitrate. Nitrate is a naturally occurring compound formed when excess nitrogen in the soil combines with oxygen. Sources of excess nitrogen in the soil include fertilizers, livestock waste and septic systems. Nitrate is commonly found in the soil of rural and agricultural areas. The most common symptom of nitrate poisoning is bluish skin coloring, especially around the eyes and mouth.
Nitrate poisoning is easy for doctors to treat and babies can make a full recovery.
Also, as babies grow, their bodies develop the ability to counteract the effects of excess nitrate. Thus, health risks are reduced for children more than 6 months old as well as healthy adults. A report on test results, along with recommendations on ways to reduce nitrates in drinking water and groundwater, will be mailed to participants. Because groundwater is subject to contaminants other than nitrate, the district recommends that well owners conduct a comprehensive test of their water every one to three years, or more frequently if the taste, odor or appearance of the water changes, or if they have specific health concerns. The free nitrate testing program is part of a comprehensive study of nitrates conducted by the district and funded by a grant from the U.S. Environmental Protection Agency and the State Water Resources Control Board.
