Ever wonder about the possibility of invisible contaminants residing in your drinking water, holding the potential to make you really sick? (Or really paranoid?)
One of our patrons did; she asked us for some help in tracking down a comprehensive list of contaminants and their MCLs (maximum contaminant levels) earlier this week. We pointed her in the direction of the good ol' Environmental Protection Agency's website, where we found an extremely helpful PDF that included a list of the National Primary Drinking Water Standards. Everything from arsenic to vinyl chloride (!) is covered, along with the corresponding potential health effects if the exposure goes over the maximum contaminant level. Common sources of the contaminant in regular drinking water are also provided.
Knowledge is power, so look out for yourselves and be safe!
