Key Water Quality Metrics
Contaminants Detected
⚠️ Contaminants Above EPA MCLG (3)
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
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
Copper
What is Copper?
Naturally occurring metal that is widely used in plumbing, faucets, and fixtures
Health Effects
Health protective levels of copper in drinking water have been established based on potential adverse effects to the gastrointestinal system, kidneys, and liver, especially for infants and children. Acute exposure to high copper levels uncommonly found in drinking water can cause nausea, vomiting, diarrhea, and stomach cramps.
