"PHILADELPHIA -- Pennsylvania officials reported incomplete test results that omitted data on some toxic metals that were found in drinking water taken from a private well near a natural gas drilling site, according to legal documents released this week."
"The documents were part of a lawsuit claiming that natural gas extraction through a method known as hydraulic fracturing, or fracking, and storage of the resulting wastewater at a site in southwestern Pennsylvania has contaminated drinking water and sickened seven plaintiffs who live nearby.
In a deposition, a scientist for the Pennsylvania Department of Environmental Protection testified that her laboratory tested for a range of metals but reported results for only some of them because the department’s oil and gas division had not requested results from the full range of tests."
