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.
An overview of the most common parameter for testing water quality
Of all the buzzwords that are swimming around the world of water quality these days, “TDS” is one of the most common. Industry professionals range from being fully versed in the subject to being marginally aware, while the average consumer would most likely guess it is an abbreviation for touchdowns. Given that TDS is by far the most common parameter for water quality testing, an overview of the subject is warranted.
