What are PFOA and PFOS?
PFOA and PFOS are artificial, toxic chemicals from the PFC family. The EPA has cited PFOS and PFOA in drinking water as a threat to public health.
PFOS and PFOA were used for decades to produce goods. Like cookware, clothing, and adhesives. Smoke stacks from factories emitted the chemicals, which drifted to the ground. When it rained, the chemicals dissolved and moved through the soil, entering ground water. PFOS and PFOA have recently phased out of production in the US. But the chemical can linger in water for decades.
PFOA is Perfluorooctanoic acid. PFOS is Perfluorooctanesulfonic acid. C8 is another word commonly used to describe PFOA.
Testing for PFOS and PFOA in Drinking Water:
The EPA has set the combined limit for PFOA and PFOS in drinking water at 70 parts per trillion. But this is only an advisory level and is not enforced. There is no national legal cap on the amount of PFOA and PFOS in drinking water. And water providers are not required by the EPA to test for PFOA or PFOS.
Since 2013, The EPA has found PFOA in the drinking water of 6.5 million people. And the chemical was detected in 94 public water systems in 27 states. The majority of samples were below the EPA advisory level. But some statewide averages were up to 175 times higher than the EPA limit.
This testing was not comprehensive. So, it’s possible PFOA and PFOS are more widespread across America. And that includes private wells and small water systems, which weren’t part of the testing.
Those near factories, airports, or military sites should test for PFOS and PFOA in their drinking water.
How to Remove PFOA and PFOS from Drinking Water:
Reverse Osmosis systems use a Nano-filtration needed to reduce them from water. We have an excellent reverse osmosis for under your kitchen sink. Click here for more information our reverse osmosis systems. .
