Testing Water Wells Near Natural Gas Wells
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…

Wastewater Injection and Earthquakes
“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.

Hydraulic Fracturing Isn’t the Problem
“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.

Reactions to EPA’s Draft Report on Wyoming Ground Water Contamination
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.

Ground Water Contamination by Hydraulic Fracturing?
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.”

Is the Criticism of Hydraulic Fracturing Deserved?
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.

Links Between Hydraulic Fracturing and Groundwater Contamination?
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 …
