Key Water Quality Metrics
Contaminants Detected
⚠️ Contaminants Above EPA MCLG (5)
Lead
What is Lead?
Naturally occurring heavy metal commonly found in tap water
Health Effects
Health protective benchmarks for oral exposure to lead are based on delays in physical or mental development for children and infants, and impacts to the kidneys and high blood pressure for adults. Children are especially susceptible to the effects of lead. Even low levels of lead can damage the brain and nervous system, slow development, and lead to problems with learning, behavior, hearing, and speech. In adults, lead can lead to hypertension, reproductive problems, neurological disorders, decreased kidney function and muscle and joint pain. Exposure to lead can also cause anemia and impact the immune system for both children and adults. The EPA classifies lead as a probable human carcinogen.
Affected Organs
Common Sources
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
Gross Alpha (Excl. Radon and Uranium)
What is Gross Alpha (Excl. Radon and Uranium)?
Gross alpha activity is a measure of the total alpha particle activity in a water sample, excluding radon and uranium. It is used to assess the presence of radioactive contaminants in drinking water.
Health Effects
Exposure to high levels of alpha radiation can lead to an increased risk of cancer, particularly in the bones and other tissues where alpha particles can deposit energy.
Affected Organs
Common Sources
Dibromoacetic Acid (DBA)
What is Dibromoacetic Acid (DBA)?
Member of haloacetic acids (HAAs) that form as byproducts when chlorine reacts with organic matter
Health Effects
Health protective benchmarks for DBA are based on carcinogenicity and liver toxicity observed in animal studies. The EPA has classified DBA as a probable human carcinogen. Results from animal studies also suggest that kidney, immune system, spleen and developmental toxicity are associated with exposure to BDCM. BDCM has been shown to produce DNA changes (genotoxicity) in laboratory studies.
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.

Understanding the Data
This data comes from your local water utility testing. The bar charts compare detected levels against EPA's Maximum Contaminant Level Goal (MCLG). Contaminants above the MCLG are shown by default and may require filtration. All other tested contaminants are within safe levels and can be viewed by expanding the section above.
