Water contamination news: Fracking – Study has raised concerns about the safety of gas drilling in the Marcellus Shale.
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
Water and sand can make up more than 99.5 percent of the fluid used to hydraulically fracture a well. Water acts as the primary carrier fluid in hydraulic fracturing. Because the multi-stage fracturing of a single horizontal shale gas well can use several million gallons of water, it is critical that large quantities of relatively fresh water be reasonably available. The quality of the water is very important because impurities can reduce the efficiency of the additives used in the process.
The U.S. Environmental Protection Agency (EPA) has released draft underground injection control (UIC) program permitting guidance for class II wells that use diesel fuels during hydraulic fracturing activities. EPA developed the draft guidance to clarify how companies can comply with a law passed by Congress in 2005, which exempted hydraulic fracturing operations from the requirement to obtain a UIC permit, except in cases where diesel fuel is used as a fracturing fluid.

Water contamination news: Fracking defined – Minimum distance urged to protect sensitive rock strata from fracking.
Artificial fissures in the earth’s crust caused by hydraulic fracturing, or fracking, typically extend less than 600 meters, according to a new Durham University study.
Water contamination news: – Archives EPA study says hydraulic fracturing likely contaminated drinking water In Wyoming town.
Industry experts have often said that most fracturing occurs a mile or more below the surface, while groundwater is close to the surface, and that there is no way that fracking water or gas could migrate to drinking water from those depths.
BROOKLYN — A standing-room-only crowd of about 350 gathered Thursday to raise questions about the oil boom transforming the landscape of Jackson County.
Judging by groans, applause and titters, a significant share of the audience was skeptical of assurances that environmental risk is minimal.
“There is nothing they can do to prevent an accident,” said John Bancroft of Norvell Township, who belongs to a group called Irish Hills Waterkeepers. “Someday there will be an accident.”
The Environmental Protection Agency announced Thursday that it suspects hydraulic fracturing in a shallow natural gas well in Wyoming contaminated a town’s drinking water. After three years of study, the agency concluded that chemicals found in the aquifer and in individual wells were consistent with those used in hydraulic fracturing.
The agency issued a report that will be open for public comment and scientific review. If it is finalized with the same conclusions, it could provide the first documented case in which “fracking” contaminated groundwater.
Natural gas companies are dumping radioactive wastewater from fracking into rivers and streams that serve as the main drinking water supply for millions of people — and “dangers to the environment and health” arising from this practice are “greater than previously understood.
