Reverse osmosis is one of the most effective technologies available for reducing a wide range of contaminants from drinking water. But why does reverse osmosis remove contaminants when ordinary filters cannot? The answer lies in the way an RO system combines pressure, a semipermeable membrane, selective separation, and multiple stages of filtration. Unlike a conventional […]

Is Reverse Osmosis Water Healthy? What You Need to Know
Is reverse osmosis water healthy? Yes. For most people, drinking water produced by a properly maintained reverse osmosis (RO) system is considered safe and can be an excellent way to reduce many contaminants found in drinking water. Reverse osmosis removes or substantially reduces a broad range of dissolved substances, including certain metals, salts, nitrate, fluoride, […]
Continue readingIs Reverse Osmosis Water Safe? What You Need to Know Before Drinking RO Water
Reverse osmosis, commonly called RO, is one of the most effective household water-treatment technologies available. It can reduce a wide range of dissolved contaminants, including many heavy metals, salts, inorganic compounds, and certain organic chemicals. The EPA describes reverse osmosis as a membrane process capable of removing a broad range of contaminants from drinking water. […]

Clean drinking water is essential for good health, but water can sometimes contain microbial contaminants—microscopic organisms capable of causing illness. These contaminants include bacteria, viruses, protozoa, and other microorganisms. Microbial contamination is particularly important because even relatively small amounts of some disease-causing organisms can create a health risk. EPA states that for microbial contaminants that […]
Continue readingBacteria and Viruses in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Bacteria and viruses are among the most important biological contaminants that can affect drinking water. Unlike many chemical contaminants, microorganisms can multiply or spread rapidly and may cause illness after relatively short-term exposure. Potential sources include human and animal waste, sewage, agricultural runoff, failing septic systems, flooding, contaminated groundwater, and problems within water distribution systems. […]

Pharmaceuticals in drinking water are an emerging water-quality concern. Trace amounts of prescription drugs, over-the-counter medications, and veterinary pharmaceuticals can enter rivers, groundwater, reservoirs, and wastewater streams and, in some circumstances, be detected downstream of treatment facilities. The important distinction is that detecting a pharmaceutical in water does not automatically mean the water is unsafe […]

Pesticides play an important role in agriculture, landscaping, pest control, and public-health programs, but some pesticide chemicals can enter drinking-water sources through agricultural runoff, groundwater contamination, stormwater, and other pathways. Whether pesticides in drinking water present a health concern depends on which pesticide is present, how much is present, and how long people are exposed. […]

Microplastics have become an increasingly important drinking-water concern as researchers continue to detect tiny plastic particles in tap water, bottled water, rivers, groundwater, and other parts of the water cycle. Unlike contaminants such as lead, arsenic, or nitrate, microplastics are particles rather than dissolved chemicals. Their size, shape, polymer type, and surface characteristics can vary […]
Continue readingNitrites in Drinking Water: Health Risks, EPA Limits, Testing & Filtration
Nitrite is a nitrogen-containing chemical that can occur naturally in the environment but is more commonly associated with fertilizer runoff, wastewater, septic systems, animal waste, and the biological conversion of nitrogen compounds. Although nitrite and nitrate are closely related, they are not the same chemical. Both are regulated in drinking water because elevated concentrations can […]
Continue readingVOCs in Drinking Water: Health Risks, EPA Guidelines, Testing & 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 […]
Continue readingIron in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
Iron is one of the most common minerals found in groundwater. While iron is an essential nutrient, elevated iron in drinking water can create significant taste, odor, staining, and plumbing problems. Water containing too much iron may appear yellow, orange, brown, or rusty. It can leave orange stains on sinks and toilets, discolor laundry, clog […]
Continue readingRadium in Drinking Water: Health Risks, EPA Guidelines, Testing & Filtration
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, […]
