Key Water Quality Metrics
Contaminants Detected
⚠️ Contaminants Above EPA MCLG (7)
Arsenic
What is Arsenic?
Naturally occurring element that has both inorganic and organic forms
Health Effects
The EPA drinking water standards for arsenic are based on adverse effects to the cardiovascular, pulmonary and liver systems in drinking water with inorganic arsenic, as well as an increased risk of cancer. Long term health effects of total arsenic in drinking water include bladder, GI tract, kidney, liver, lung, pancreas and skin cancer, cardiovascular effects, pulmonary and gastrointestinal effects, ocular, immunological, neurological and reproductive effects. Arsenic found in epidemiological studies include developmental effects, socioeconomic and genotoxicity.
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
Radium 228
What is Radium 228?
Radium-228 is a radioactive isotope of radium that occurs naturally in uranium and thorium ores. It is part of the decay chain of uranium-232 and has a half-life of 5.75 years. Radium-228 can be found in groundwater and can contaminate drinking water supplies.
Health Effects
Exposure to radium-228 can lead to an increased risk of cancer, particularly bone cancer, due to its radioactive properties. Long-term exposure can also affect the kidneys and other organs.
Affected Organs
Common Sources
Radium 226
What is Radium 226?
Radium-226 is a radioactive isotope of radium, which is a naturally occurring element found in uranium ores. It is a decay product of uranium-238 and is known for its radioactive properties, emitting alpha particles and gamma radiation.
Health Effects
Exposure to Radium-226 can lead to serious health issues, including an increased risk of bone cancer and other malignancies. It can accumulate in bones and tissues, leading to long-term health effects due to its radioactivity.
Affected Organs
Common Sources
Chloroform
What is Chloroform?
Member of trihalomethanes (THMs) that form in water treated with chlorine and is generally the most abundant THM formed in drinking water
Health Effects
Health protective benchmarks for chloroform have been developed based on kidney and liver carcinogenicity observed in animal studies, and liver toxicity observed in occupational studies. The EPA classifies chloroform as a probable human carcinogen based on animal evidence, and there is additional epidemiological evidence that may increase the risk of colon and bladder cancer in humans. Results from animal studies also suggest that exposure to chloroform can cause liver, developmental and immune toxicity. Acute exposure to low levels of chloroform will cause nervous system toxicity.
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.
Affected Organs
Common Sources
Fluoride
What is Fluoride?
Naturally occurring mineral in the environment and an essential element of tooth enamel
Health Effects
Elevated levels of fluoride in drinking water can lead to dental fluorosis in children, which is the discoloration and molting away of tooth enamel. Evidence on low-dose, chronic exposure to fluoride is not definitive but has been indicated as having potential neurological impacts. Studies have clearly established that long-term exposure to high doses of fluoride, higher than typically found in US drinking water, can have adverse effects on skeletal tissue (bones and teeth), which may cause higher risk of bone fractures in seniors. Skeletal fluorosis is a debilitating condition caused by high fluoride exposure during bone development in children.

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.
