Most consumer water purification systems are not designed to remove hazardous micropollutants.
An Olympic-sized pool contains 660,253 gallons of water. Three drops of PFOS can make it unsafe.
PFOS bioaccumlates and is now found in the blood serum of 97% of the U.S. population.
90% of consumed prescription drugs end up in waste water.
They are Ubiquitous. Community water systems supply tap water to 85% of the U.S. population. Local wells serve the remaining 15%. Hundreds of micropollutants have been identified in both water sources.
The drinking water of over 100 million Americans contains micropollutants
5 things to know about micropollutants
Hard to Remove. At parts per trillion concentrations, many micropollutants easily pass through municipal drinking water treatment plants as well as consumer water filtration systems.
Harmful to Health. A growing number of contaminants, including the pesticides atrazine and chlorpyrifos, estrogens, bisphenol A (BPA), and perfluorinated compounds such as PFOA and PFOS, are linked to cancer, brain and nervous system damage, developmental defects, fertility problems and endocrine disorders.
Broad Range. Micropollutants found in drinking water include pesticides, pharmaceuticals, industrial chemicals, fluorocarbons, solvents, and substances used in personal care products.
Highly Toxic. Many water quality limits are expressed in parts per trillion. One part per trillion is equivalent to a single drop of food coloring in 18 million gallons of water. The EPA advisory limit for the micropollutants PFOA or PFOS is 70 parts per trillion. This means that only one drop of either substance will make over 250,000 gallons of water unsafe for consumption.
