6 Tips to Help You Choose the Best Water Filtration System A five-year study conducted by the Environmental Working Group (EWG) between 2004 and 2009 found that most of the municipal water in the US contains 316 potentially harmful chemicals and microbial contaminants including, among others, heavy metals, pesticides, industrial chemicals such as perfluorochemicals (PFCs), and pharmaceutical residues. Out of these 316 contaminants, the US Environmental Protection Agency (EPA) only regulates 114 of them, meaning your municipal water likely contains unhealthy doses of the remaining contaminants.
In fact, in addition to the regulated chemicals, most municipal water contains up to 30 unregulated contaminants, according to the aforementioned report. This essentially means that government bodies such as the EPA need to do much more to ensure your municipal water is clean and safe.
