VOCs in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration

VOCs in drinking water and volatile organic compound filtration

Volatile organic compounds, commonly called VOCs, are a broad group of carbon-based chemicals that can enter drinking water from industrial activity, fuels, solvents, pesticides, landfills, manufacturing, and other sources. Some VOCs can contaminate groundwater and private wells for years without changing the water’s appearance. Depending on the specific chemical and level of exposure, long-term exposure […]

Radium in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration

Radium contamination in drinking water and filtration treatment

Radium is a naturally occurring radioactive element that can be found in groundwater, particularly in areas where certain rocks and soils contain naturally occurring radioactive materials. Although radium is usually present at very low levels, elevated concentrations in drinking water can pose long-term health risks and require treatment. Unlike contaminants that primarily affect taste, odor, […]

Sulfur in Drinking Water: Causes, Health Risks, EPA Guidelines, Testing & Filtration

Sulfur in drinking water and hydrogen sulfide water treatment

Sulfur in drinking water is a common concern for homeowners, particularly those with private wells. The most recognizable symptom is often the familiar “rotten egg” smell that can come from faucets, showers, and water heaters. However, “sulfur in water” can refer to several different substances. Hydrogen sulfide (H₂S) is primarily responsible for the rotten-egg odor, […]

Manganese in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration

Manganese contamination in drinking water

Manganese is a naturally occurring mineral that the human body needs in small amounts. It plays a role in normal bone formation, metabolism, and other biological processes. However, elevated manganese concentrations in drinking water can become a concern, particularly with prolonged exposure. Manganese is also a common water-quality and aesthetic problem. Elevated levels can cause […]

Copper in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration

Copper pipes that can contribute copper to drinking water

Copper is an essential mineral that the human body needs in small amounts. However, too much copper in drinking water can cause health problems, particularly at elevated concentrations. Copper contamination is also relatively unusual because it often doesn’t originate at the water treatment plant—it can enter drinking water as water travels through household plumbing. If […]

Chromium-6 in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration

Chromium-6 contamination in drinking water

Chromium-6, also called hexavalent chromium or Cr(VI), is a form of chromium that can occur naturally in groundwater and can also enter water supplies through industrial activities. Because chromium-6 is odorless and tasteless, you cannot determine whether it is present in drinking water by looking at, smelling, or tasting the water. For homeowners concerned about […]
