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

nervous-systemdevelopmentalreproductive-mreproductive-fkidneysimmune-systemcarcinogenscardiovascularblood

Common Sources

Enters drinking water primarily through the corrosion of pipes, fixtures, solder and service linesErosion of natural lead deposits and industrial waste streams can also increase levels of lead in drinking water
Last Tested: Jul 7, 2022

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

nervous-systemdevelopmentalrespiratoryimmune-systemeyescarcinogenscardiovasculargastrointestinal

Common Sources

Present in the earth's crust and is present in the different inorganic forms in minerals and soilArsenic can enter groundwater via the erosion of arsenic-containing mineral and rock deposits in the earth's crustInorganic arsenic enters drinking water through corrosion of arsenic-containing mineral and rock deposits present in the aquiferPreviously enhanced the environment via past contamination sources remain relevantErosion of natural lead deposits and industrial waste streams can also increase levels of lead in drinking water

What is Chromium (VI)?

Chromium VI, also known as hexavalent chromium, is a toxic form of the element chromium. It is a known carcinogen and can cause various health issues when ingested or inhaled. Chromium VI is often used in industrial processes, such as chrome plating, leather tanning, and wood preservation.

Health Effects

Exposure to chromium VI can lead to serious health problems, including lung cancer, respiratory issues, skin irritation, and damage to the liver and kidneys. Long-term exposure can also affect the immune system and lead to reproductive issues.

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

Chlorine disinfection interacting with naturally occurring organic matter in distribution systemsLevels usually higher in surface water than groundwaterReleased into the environment from chemical manufacturing plants, pulp and paper mills, waste incinerators and wastewater treatment plants
Last Tested: Jul 7, 2022

What is Sulfate?

Anion composed of sulfur and oxygen, is almost universally present in water

Health Effects

Elevated sulfate concentrations may have a short-term laxative effect and cause dehydration, especially among infants. There are no known chronic health risks associated with sulfate.

Affected Organs

gastrointestinal

Common Sources

Dissolves into groundwater as it passes through mineral deposits, soil, and rock formations that contain sulfate mineralsWaste streams from industrial activity or agricultural runoff can also contribute to sulfate in groundwater or surface water suppliesAluminum sulfate is often used in conventional water treatment, which can contribute sulfate to drinking water

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.
