The feds have issued a health advisory for C8 in drinking water.
This week, the Environmental Protection Agency issued a provisional health advisory of 0.4 parts per billion for C8, slightly stricter than the temporary benchmark of 0.5 parts per billion which had been established for drinking water in the Mid Ohio Valley.
Though epidemiological studies are inconclusive as to health effects for humans, the agency formula takes into account the uncertainty over the safety of the manufacturing chemical for humans.
The health advisory issued this week includes the substances PFOA and PFOS, which are both known for their durability and water and grease resistant properties. The provisional health advisory for PFOS, also familiar as the Scotchgard chemical, was set at 0.2 parts per billion.
