Alto Water Quality Test Results
Key Water Quality Metrics
Contaminants Detected
⚠️ Contaminants Above EPA MCLG (5)
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
Uranium
What is Uranium?
Uranium is a weakly radioactive heavy metal found naturally in bedrock and used in nuclear weapons, some ceramics, electron microscopy stains, photography toners, and certain fertilizers. Uranium is weakly radioactive because all of its isotopes (Uranium-234, Uranium-235, and Uranium-238) are unstable. Ninety-nine percent of naturally existing uranium is in the isotope form uranium-238. The EPA has established a maximum contaminant level for uranium in drinking water in response to human and animal studies indicating kidney toxicity and and increased risk of cancer.
Health Effects
Health protective benchmarks for uranium are based on adverse kidney system effects observed in both humans and animals and an increased risk of cancer. Animal studies have also shown female reproductive system and developmental toxicity, as well as genotoxicity, related to uranium exposure.
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
Chlorine (Total)
What is Chlorine (Total)?
Chlorine is a chemical element with the symbol Cl and atomic number 17. It is a yellow-green gas at room temperature and is a strong oxidizing agent. Chlorine is commonly used in water treatment to kill bacteria and other pathogens, making water safe for drinking.
Health Effects
Exposure to chlorine can cause respiratory issues, skin irritation, and eye irritation. Ingesting high levels of chlorine can lead to gastrointestinal distress and other serious health problems.
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.
