Will boiling my water help?
No. Boiling water will NOT reduce nitrate levels. In fact, it will make the level of nitrate worse because some of the water will evaporate but the nitrate will not. This increases the concentration of nitrate in water.

Is it safe to shower or bathe in water if it is over the nitrate MCL of 10 mg/L?
Nitrate is only a concern for ingestion (eating and drinking). It is not absorbed through your skin. People who install filter systems for nitrate often install them just for their kitchen sink faucet, and they use that faucet for their cooking and drinking water.

Why is nitrate contamination a concern?
Nitrate is an acute contaminant, meaning that health effects can occur immediately (I.e. within hours or days) of short-term exposure. Too much nitrate in your body makes it harder for red blood cells to carry oxygen. While most people recover quickly, this can be very dangerous for infants and some…

How are people potentially exposed to nitrate?
For many situations, the potential for children’s exposure from drinking water is medium to low. The potential can be higher when private wells become contaminated with nitrates from feed lot and agricultural runoff, and contaminated groundwater. Some geographic areas are at higher risk of drinking water contamination of private wells…

What are the possible health effects of nitrate exposure?
Short-term: Excessive levels of nitrate in drinking water have caused serious illness and sometimes death. The serious illness in infants is due to the conversion of nitrate to nitrite by the body, which can interfere with the oxygen-carrying capacity of the child’s blood leading to blue baby syndrome (methemoglobinemia). This…
