PFOA and PFOS in Water
PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate) are highly toxic synthetic chemicals commonly used to manufacture teflon cookware, carpet, clothing, pizza boxes and airport fire-fighting chemicals. They can enter the water supply from chemical dumping, water run-off, landfills and air fields. Contamination is usually located near a source of the chemicals and can affect private wells and municipal water supplies.
Health Effects of PFOA and PFOS: PFOA and PFOS could also be dangerous to pregnant women. Some studies indicate development problems and low birth weight. Other health issues include high cholesterol, thyroid cancer, testicular cancer, ulcerative colitis and kidney cancer.
How to Remove PFOA and PFOS: In most cases a whole-house activated carbon filter is the best Available Technology (BAT) for removal of these chemicals. Another option is a WECO reverse osmosis filtration system. This complete 5-stage water purification system removes tastes and odors along with suspended particles like sand and grit, chlorine, chloramine, carcinogenic chemicals, pesticides, solvents, and heavy metals like lead, cadmium, copper and arsenic. WECO whole-house and commercial filtration systems are also available.
