Water treatment system delivers high-purity water to a research laboratory
The U.S. Environmental Protection Agency (EPA) has long regulated radium in drinking water, but in December 2000 the EPA lowered the maximum allowable levels for radionuclides. As a result, water utilities across the country retested for radium. Those that found radium contamination exceeding new EPA standards faced a three-year deadline to comply—by either removing the radium to improve the quality of the existing water supply or finding alternative water sources.

Are PFCs the next public water concern?
Like other manmade chemicals that have been polluting our drinking water over the years, perfluorochemicals (PFC) are not naturally occurring chemicals; they were developed in a lab- oratory to meet an industry need. PFCs are carbon chains (typically four or eight carbon atoms) that are bonded to fluorine atoms.
PFCs can be used as an ingredient in a manufacturing process or as part of a finished product. Companies have used them for a number of years for products that resist heat, oil, grease and water.
