Is your tap water safe to drink?

Americans prefer drinking bottled or filtered water than tap water which is free. They claim that tap water should contains impurities that may lead to health problems. But according to Environmental Protection Agency (EPA), there is nothing to worry about.

But is there a problem with tap water in the United States? Not according to the Environmental Protection Agency (EPA), which reports that more than 90 percent of water systems in the country exceed standards. (The nonprofit Natural Resources Defense Council finds that a few major cities, including Atlanta, San Francisco and Albequerque, N.M.,fall short.) “[In general] it is definitely safe for you to turn on the tap,” says Jack Hoffbuhr, executive director of the non-profit American Water Works Association, which represents 57,000 water industry workers from treatment plant operators to regulators. Compared to other countries, America has one of the best water systems in the world, he says. Water utilities monitor for more than 103 contaminants and must comply with the EPA’s standards on 80 of the most harmful, including disease-causing microbes and synthetic industrial material. While some traces of contaminants may remain, as long as they occur within the limits of EPA standards, they pose no significant health threats, according to the NRDC.
