Water utilities should notify consumers when perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) exceed 70 parts per trillion—individually or combined—in drinking water, under new guidelines released on May 19 by EPA.

The long-awaited advisory aims to reduce chronic exposures to the persistent fluorochemicals in drinking water. Environmental groups, who have long been pushing EPA to set a limit for the fluorochemicals in drinking water, are disappointed that the advisory is only voluntary. The agency “highlights the fact that this is a chemical that you do not want in your water or the environment,” says David Andrews, senior scientist at the Environmental Working Group, an environmental advocacy organization. “But we think [EPA] could have taken a bigger step to protect public health,” he adds.

The chemicals, which were used to manufacture iconic household brands such as DuPont’s Teflon and 3M’s Scotchgard, persist indefinitely in the environment and have been linked to disease in humans. More than a decade ago, the fluorochemical industry pledged to end production of PFOA and PFOS by 2015. EPA says that the companies have met their stewardship commitments.

Most of the readers of this news would look for numeral "the limit" value. It's definetly an incomplete news!

no amount of pfoa-pfos should be allowed as it bioaccumulates in liver bone marrow blood and kidneys. the.00000007 parts per trillion standard will allow a 1 gram accumulation with exposure at 2 liters a day for 48 years. vitamine B12 may release many hundred thousands of fluoride atoms to cause dental and skeetal fluoris kidney damage. allpfoa- pfos sites can be remeadiated by carbon filtering the affected water source and stopping secondary spreads in the down stream chains.

It could be researched as water fluoridation by-products
