Do you know what is in the water you drink? It is not just H2O, according to the new study. The Environmental Watch Group studied tap water in 42 states, including Pennsylvania, and found over 100 unregulated chemicals. The most common ones were disinfection byproducts, nitrates, chloroform, barium, arsenic, and copper. The top ten worst list included California, Wisconsin and Arizona, with Pennsylvania in at number 9.

Marty Ward works with the Johnstown Water Authority. He tells Channel 6 News, "We have run tests on everything that we've been required to, which includes unregulated chemicals. In the Johnstown system we have never had any of them detected."

Marty Ward tests your water for contaminants and cleans it out before it is sent to you to drink. The Johnstown Water Authority gets it from the Quemahoning, Dalton, and North Fork Dams. It is filtered and treated with chlorine, lime, alum, fluoride and phosphate. It is then pumped into tanks allowing the chlorine to kill the bacteria. At the end it is pumped into the distribution system. The process, Ward says, is not too extensive for a reason. Ward says, If you start with a good product it makes it easy to end with a good product."

The E.W.G. survey blames agriculture, industry, and urban and sprawl developments for the chemicals in tap water. Ward says, "I think the biggest problem for the state of Pennsylvania is that we have so many small systems that do not have the money or the resources to do as good a job as they probably wish they could."
