“Having clean and safe drinking water isn’t a privilege, it’s a right,” said Paul Pestano, an EWG research analyst and a lead researcher on the new filter guide. “However, in the real world much of America’s drinking water contains various contaminants. These can be reduced by investing in the appropriate filtration system.”
A glass of water from the kitchen sink can often contain a number of contaminants, including known and probable carcinogens, substances toxic to the endocrine and nervous systems and chemicals that may have risks to pregnancy and development.
Tap water contaminants come from a wide variety of sources. Among the major culprits are pesticides and chemicals from fertilizer- and manure-laden farm runoff; factory discharges; polluted runoff from wastewater treatment plants; and pollutants that leach from pipes and storage tanks.
By choosing the right water filtration system, many pollutants can be dramatically reduced or even eliminated. In addition, consumers can save hundreds or thousands of dollars a year by not buying bottled water and instead investing in a filter.
There are thousands of water filters on the market today. Not all of them live up to their promises. Some filters use a combination of technologies, while others rely on just one. There are several different categories of filters that can differ widely in both price and relative effectiveness: pitcher; faucet-mounted; countertop; under-sink and water softener.
EWG has reviewed 137 filter systems that have been certified by the California Department of Public Health and/or NSF, a reputable independent product evaluation company.
“Depending on where you live, you and your family could be drinking a cocktail of various contaminants,” Pestano said. “Some of these could pose long-term health problems on their own. Consuming them in combination could be even worse.”
