⚠️ Contaminants Above EPA MCLG (6)
Perfluorooctanesulfonic acid
What is Perfluorooctanesulfonic acid?
Part of a class of synthetic compounds known as per- and polyfluoroalkyl substances (PFAS) widely used to make products more resistant to stains, water, and grease. It is found in fabrics, fire-fighting foams, cleaning products, hydraulic fluids, metal plating, and paper. Although PFOS production has been phased out in the US, exposure is still a major concern due to its high degree of persistence in the environment and in the body as well as the use of legacy products and imported goods. Many adverse health effects have been linked to PFOS exposure, including developmental, liver, and immunological problems and increased cancer risk. EPA has found that there is suggestive evidence that PFOS is a human carcinogen.
Health Effects
As with many PFAS compounds, research into the health effects of PFOS is rapidly evolving. Epidemiological studies have shown associations between elevated PFOS levels and increased total and low-density lipoprotein cholesterol ('bad cholesterol') as well as immune toxicity (decreased antibody response). Animal studies indicate that PFOS exposure is related to adverse developmental effects, liver toxicity, immune toxicity, and an increased risk of liver and pancreatic cancer.

Perfluorooctanoic acid
What is Perfluorooctanoic acid?
Perfluorooctanoic acid (PFOA) is a synthetic chemical that belongs to a group of chemicals known as per- and polyfluoroalkyl substances (PFAS). It is used in various industrial applications and consumer products for its water- and grease-resistant properties.
Health Effects
Exposure to PFOA has been linked to several health issues, including developmental effects in fetuses, increased cholesterol levels, liver damage, thyroid disease, and certain types of cancer.
Affected Organs
Common Sources
Dichloroacetic Acid (DCA)
What is Dichloroacetic Acid (DCA)?
Member of haloacetic acids (HAAs) that form as byproducts when chlorine reacts with organic matter
Health Effects
Health protective benchmarks for DCA are based on evidence of increased cancer risk and liver toxicity observed in animal studies. Adverse effects to the male reproductive system have also been associated with elevated levels of DCA in animal studies. The EPA classifies DCA as a likely 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
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
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.
