A study of tainted drinking water

If health officials find human exposures are occurring at levels above the MRL, they may want to investigate further but that does not mean people will become sick from those exposures. Human health effects include pregnancy-induced hypertension, liver damage, elevated cholesterol, increased risk of thyroid disease, and decreased fertility.

The man-made chemicals were used in consumer products including nonstick cookware and flame-resistant fabrics, and have been phased out by U.

For two of the chemicals, the report advocates limits that are much stricter than those recommended by the Environmental Protection Agency, and stronger than levels currently being implemented by New Jersey, a national leader in regulating the chemicals.

Isotopes and traces of ethane in the methane indicated that the gas was not created by microorganisms living in groundwater but by heat and pressure thousands of feet down in the Marcellus Shale, which is where companies fracture rock to release gas that rises up a well shaft.

EWG frets that the remaining chemicals, which have no mandatory federal safety standards, can come in potentially toxic combinations for long-term consumption. The annual water quality reports that utilities are required to send customers provide a partial picture, the study says, as they contain no information on unregulated chemicals.

The list was the longest ever compiled by the agency under a law requiring it to evaluate possible tap-water pollutants every five years and make regulatory determinations for at least five of them. The EWG study says the nation should adopt new policies for drinking water that include regulating more contaminants and spending more money on measures that prevent pollution.

Yet some scientists maintain that chemical analysis of the gas can reveal whether it slowly bubbled up through thousands of feet of rock or zipped up a leaky well. But by denying even the possibility that some wells may leak, the drilling companies have undermined their own credibility.

The Environmental Working Group analysis of 20 million tap water quality tests found a total of contaminants -- including industrial solvents, weed killers, refrigerants and the rocket fuel component perchlorate -- in water supplied to the public between and EPA regulates of those pollutants, setting maximum legal levels that water utilities achieved 92 percent of the time, according to the study.

The chemicals are not regulated by the federal government, but have been subject to increasingly tough limits by state officials responding to growing evidence of risks to public health. Leaky wells have to be identified first, however.

Has fracking tainted your water? Scientists say EPA safety study was censored

ATSDR, a unit of the Department of Health and Human Services, has been under pressure from public health advocates and some lawmakers to release the study following media reports that publication had been blocked by the White House and the EPA because of wide differences between the two sets of recommendations.

Any decision to regulate the chemicals at the federal level would have to be made by the EPA, which would use the ATSDR report in its evaluation, advocates said.

This water may be legal, but it raises serious health concerns. The DEP did not respond to a request for comment. The methane concentration in homes less than one mile from a fracking well was six times higher than the concentration in homes farther away. Anthony Ingraffea, a fracking expert at Cornell University, is combing through the inspection reports for most of the 41, gas wells drilled in Pennsylvania since January Minimum risk levels are estimates of the amount of a chemical that a person can eat, drink or breath each day without a detectable risk to health, the ATSDR said.

Thomas Fuchs Advertisement In Pennsylvania, the closer you live to a well used to hydraulically fracture underground shale for natural gas, the more likely it is that your drinking water is contaminated with methane.
