FAQs

Question:  Does drinking water have to be monitored for radioactivity?


Answer:  Yes. Radionuclides are naturally present in all rocks and soil. Miniscule amounts leach into surface and ground water. The most common natural radionuclides found in water are radon-222, radium-226, radium-228, uranium-238, and uranium-234. The Federal EPA regulates the level of radionuclides in drinking water to levels considered safe under the Safe Drinking Water Act.


Question:  Why does the County Department of Health test for radionuclides in drinking water?


Answer:  County ordinance mandates that its drinking water mirror Federal and State laws concerning the allowable amount of radioactivity in public drinking water. The Missouri Department of Natural Resources contracts our laboratory for regulatory testing of the State’s water supplies.


Question:  Does the EPA Safe Drinking Water Act regulate private well owners?


Answer:  No, EPA does not have the authority to regulate private water supplies. The EPA Safe Drinking Water Act covers pubic drinking water systems, which are defined as publicly or privately-owned water sources that serve at least 25 people or 15 service connections for at least 60 days per year. For a fee, Missouri residents can have their private water tested by the Environmental Health Laboratories.


Question:  Where can I find data on Saint Louis County’s drinking water?


Answer:  Public water supplies are required to make annual Consumer Confidence Reports available to their customers.
