Key Water Quality Metrics
Contaminants Detected
⚠️ Contaminants Above EPA MCLG (3)
Radium, combined (-226 & -228)
What is Radium, combined (-226 & -228)?
Radium is a naturally occurring radioactive metal that is part of the uranium decay series. It is found in trace amounts in soil, rock, and water. Radium is known for its radioactive properties and can emit alpha, beta, and gamma radiation. It is a heavy metal and can be harmful to human health when ingested or inhaled.
Health Effects
Exposure to radium can lead to serious health issues, including an increased risk of cancer, particularly bone cancer. It can also cause damage to the bone marrow and other organs. Long-term exposure may result in anemia, immune system suppression, and other health complications.
Affected Organs
Common Sources
Total THMs
What is Total THMs?
Group of contaminants that form in drinking water systems when a disinfectant, typically chlorine, reacts with organic matter
Health Effects
Drinking water standards for total THMs are based on evidence of carcinogenicity in human and animal studies, as well as liver and kidney toxicity observed in animal studies. Individual THMs have been further associated with developmental, immune, spleen, and genotoxicity.
Affected Organs
Common Sources
Trichloroacetic Acid (TCA)
What is Trichloroacetic Acid (TCA)?
Member of haloacetic acids (HAAs) that form as byproducts when chlorine reacts with organic matter
Health Effects
Health protective benchmarks for TCA in drinking water have been developed based on liver toxicity and carcinogenicity observed in animal studies. EPA has classified TCA as a possible human carcinogen. Developmental toxicity has also been associated with exposure to TCA based on evidence from animal studies.
