Weak records cited on Pa. shale pollution

Even when pollution discharges from shale gas well pads and impoundments contaminate private water supplies, those violations often go unrecorded or publicly reported by state environmental regulators, according to documents filed in the Pennsylvania Superior Court case challenging the constitutionality of the state’s oil and gas law, Act 13.

More evidence for (and against) groundwater contamination by shale gas

Due to the differences in geological location of Pennsylvania and Arkansas, studies of leakage will differ depending on the state it is recorded in.

Fracked Pennsylvania shale could be naturally leaky

In 2011, researchers from Duke University published results showing a correlation between methane concentrations in private water wells and proximity to local natural gas production wells in parts of Pennsylvania and New York. While that suggested the water well contamination could be related to recent fracking, it was not at all a sure thing.

EPA steps away from fracking investigation in Wyoming

EPA announced that it will step back from the investigation for The Wyoming Department of Environmental Quality and the Wyoming Oil and Gas Conservation Commission to further investigate groundwater conditions around Pavillion with support from the EPA.

How the EPA linked “fracking” to contaminated well water

A new investigation by the US Environmental Protection Agency (EPA) at a site in Wyoming is one of the first to look thoroughly at the potential link between fracking operations and groundwater contamination. The agency’s report provides a clear link between fracking and water supply problems.

EPA fracking investigation in Wyoming revisited after objections

EPA fracking investigation in Wyoming revisited after objections

In December 2011, Ars reported on a major EPA study in Pavillion, Wyoming that concluded hydraulic fracking operations there had contaminated the groundwater aquifer. While there wasn’t a clear link to contamination detected in some shallow private water wells, EPA believed the deeper contamination was very likely related to fracking.

Seepage pathway assessment for natural gas to shallow groundwater during well stimulation, production and after abandonment

Seepage pathway assessment for natural gas to shallow groundwater during well stimulation, production and after abandonment

Geo Montréal evaluates the potential pathways of fugitive gas seepage during stimulation and production and concludes that the quality of surface casing and deeper casing installations is a major concern with respect to future gas migration. The pathway outside the casing is of greatest concern, and likely leads to many wells leaking natural gas upwards […]

Polluted Water Fuels a Battle for Answers

Reverend David Hudson, a resident of DeBerry Texas, sent water from his well to be tested for pollutants after he noticed it had a metallic flavor and sharp smell, and found out that high levels of chlorides and other chemicals found in drilling waste were contaminating the town’s water. Nearly a year after receiving the […]

New Study Predicts Frack Fluids Can Migrate to Aquifers Within Years

A new study has raised fresh concerns about the safety of gas drilling in the Marcellus Shale, concluding that fracking chemicals injected into the ground could migrate toward drinking water supplies far more quickly than experts have previously predicted. The study concluded that natural faults and fractures in the Marcellus, exacerbated by the effects of […]

Duke study finds methane in well water near gas drilling sites

A study from Duke University finds that methane levels in private water wells average to 17 times higher when within 1,000 yards of a natural gas drilling site. Both industry professionals and researchers agree that more studies need to be done.
