With population growth and pervasive commercial activity, drinking water resources have
been contaminated by industrial, agricultural and municipal wastewater streams.

What are Micropollutants
Low concentration, high risk
Micropollutants are a large class of contaminants consisting of industrial chemicals, pesticides, pharmaceuticals, and personal care products. Labeled “micro” due to their presence in concentrations of one part per billion and less. One part per billion (1 ppb) is one microgram per liter, or one teaspoon in an Olympic-sized swimming pool.
Many micropollutants do not biodegrade and can accumulate in people, retaining potency in trace concentrations. The continuous ﬂow and buildup of these compounds into water resources are having harmful effects on water resources, and are of serious health concern to people.
Furthermore, these compounds combine to form hazardous contaminant cocktails that are not removed at water treatment facilities, eventually making their way back into drinking water resources and the food chain. Read more: Industry News
What is PFOA
Hazardous even at 1 teaspoon
per 14 Olympic swimming pools
Perﬂourooctanoic Acid (PFOA) and Perfluorooctanesulfonic Acid (PFOS) are highly toxic pollutants, associated with liver damage, thyroid disease and cancers. EPA recently set a new health advisory level of .07 ppb for the contaminants, with negative health effects indicated at lower concentrations.
PFOA, PFOS and and related per- and polyfluorinated alkyl substances (PFASs) are known for their use in household products like Teﬂon, Scotgard and in aviation foam ﬁre fighting retardants. PFASs are colorless and soluble in water, and migrate easily from soil to groundwater.
U.S. water systems serving more than 10,000 customers were recently surveyed, and reported that 194 water supplies, affecting 16.5 million residents in 33 states, showed contamination by PFASs. Water systems serving less than 10,000 customers, representing one-third of the country, were not included in this report.
During 2016, several public health agencies declared states of emergency with respect to local water systems in the Northeast and at military airbases across the country. Read more: Industry News
