  • 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…

  • Will samples be collected after cleaning is completed?

    Indoor air or surface samples will not be collected as part of this cleaning program. Indoor sampling is not recommended since exposure pathways for volatile organic chemicals (VOCs) have been effectively managed though site engineering controls and an extensive network of air monitoring and sampling equipment. Any VOCs that may…

  • 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…
