EPA Proposes First-Time Risk Values For Chronic PFC Exposures

摘要

EPA's water office is proposing first-time draft risk estimates for chronic drinking water exposures to two ubiquitous perfluorochemicals (PFCs), values that will eventually allow regulators to craft health advisory levels and cleanup requirements at sites contaminated with the substances that have been widely used but are now being phased out. But the proposed risk values are likely to be controversial with liable parties facing potential additional cleanup requirements and with some community plaintiffs potentially facing exposures above the advisory and regulatory levels that the agency may eventually derive from its risk estimates.
