“A new study by scientists at Duke University and the U.S. Geological Survey (USGS) finds no evidence of groundwater contamination from shale gas production in Arkansas.” Quoted from the Duke University press release.More at Duke University.
The National Ground Water Association has published an information guide for people who have private water supply wells located near oil and natural gas drilling. They explain the types of water quality concerns that might be present and explain the o…More at National Ground Water Association.
“Scientists have linked a rising number of quakes in normally calm parts of Arkansas, Texas, Ohio and Colorado to below-ground injection. In the last four years, the number of quakes in the middle of the United States jumped 11-fold from the three decades prior.” Quoted from the Columbia University press release.More at Columbia University.
Colorado has become the first state to require drilling companies to do ground water testing before and after drilling a well.More at Seattle PI.
USGS has published a report titled: Dissolved Methane in New York Groundwater. The study includes data collection to document the natural occurrence of methane in New York Aquifers.More at USGS.
EPA has tested drinking water from Dimock, Pennsylvania and reports that it is safe to drink. There has been a long dispute about contamination of Dimock area water by hydraulic fracturing.More at NorthCentralPA.com.
“Hydraulic fracturing of shale formations to extract natural gas has no direct connection to reports of groundwater contamination [...] many problems ascribed to hydraulic fracturing are related to processes common to all oil and gas drilling operations, such as casing failures or poor cement jobs.” Quoted from the University of Texas at Austin press release.More at University of Texas at Austin.
Encana has responded to EPA’s draft report titled: Investigation of Ground Water Contamination near Pavillion, Wyoming.More at Forbes.
A number of people are reacting to EPA’s draft report: “Investigation of Ground Water Contamination near Pavillion, Wyoming” which links hydraulic fracturing to fresh water aquifer contamination. Hydraulic fracturing in they Wyoming study was done just 1200 feet below the ground while the fracturing done in the major shale gas plays in other parts of the country occurs and far greater depths.More at FuelFix.com.
EPA has issued a draft report titled: Investigation of Ground Water Contamination near Pavillion, Wyoming. From the conclusions: “Using this approach, the explanation best fitting the data for the deep monitoring wells is that constituents associated with hydraulic fracturing have been released into the Wind River drinking water aquifer at depths above the current production zone.”More at EPA.
In a NewsOK.com article, Larry Nichols, of Devon Energy says that hydraulic fracturing for natural gas and oil is receiving too much blame for contaminating ground water and causing earthquakes.More at NewsOK.com.
Early results from a University of Texas at Austin study of hydraulic fracturing and groundwater contamination suggest that there is no direct link between the fracturing and contamination. Problems of contamination are instead related to other parts …More at University of Texas at Austin.
