Boil Water Notice Brochure
Treatment for microbial contamination may be applied either where the water enters the home (point of entry) or at the point where drinking water is drawn (point of use). Consumers may boil their water or install a point-of-use or point-of-entry water treatment system certified for total microbial (e.g., bacteria, viruses and protozoa) reduction. If you have a POU or POE treatment system already in…

Flooding Precautions Fact Sheet
Water may not be safe to drink, cook or clean with after an emergency such as a flood. During and after flooding, water can become contaminated with microorganisms such as bacteria, sewage, heating oil, agricultural or industrial waste, chemicals and other substances that can cause serious illness. People with private drinking water wells in flooded areas can take precautions and…

Manganese Fact Sheet
Manganese is a mineral that is found naturally in the environment and is one of the most abundant metals on the earth’s surface, in air, water, and soil. It can be found in both groundwater and surface water from natural sources or as a result of human activity such as mining and industrial discharges. …

Flouride Fact Sheet
Fluorine is a natural trace element and exists in almost all soils. Fluoride is classified as any binary compound of fluorine with another element. Perhaps the most widely known use of fluoride is its addition to public drinking water supplies at about one milligram per liter (mg/L) of a fluoride salt, measured as fluoride, for…

Emerging Contaminant Removal and Microbial Growth in POU Membrane Filtration and Activated Carbon
Emerging Contaminant Removal and Microbial Growth in POU Membrane Filtration and Activated Carbon systems are common point-of-use (POU) water filtration systems. They are used to remove contaminants from drinking water, including trace-level emerging contaminants, as the last barrier to protect human health before consumption.

Emerging Contaminant Consumer Study
This independent study was performed by researchers from the University of Wisconsin system in June 2021, to gauge the American public’s knowledge of emerging contaminants in drinking water and their interest and willingness to pay for Point-of-Use (POU)/Point-of-Entry (POE) home water filtration devices. POU devices treat drinking water at the point of consumption (e.g., kitchen…

Silver Fact Sheet
Biologically, silver is a nonessential, non-beneficial element to humans. There are no scientific studies to show adverse health due to its presence in drinking water from natural sources. However, because of its bactericidal abilities, silver is used as a water bacteriostat in carbon containing water filters. The silver is deposited onto the carbon granules to…
