Fracking waste water recycling is not a panacea

Thursday, March 17, 2011
Drilling for natural gas started climbing sharply 10 years ago, energy companies faced criticism about an extraction process of pumping million litres of water in the soil for each well installation, and can be significant amounts of hazardous contaminants in the water, which comes back to the surface. Thus began in a movement", hailed by industry as a major turning point, drilling companies reuse and recycling of waste water."Water recycling a win-win situation ", says a drilling company, resources on your site.""It reduces fresh water demand and eliminates the need to dispose of the water."But the win-win situation comes with significant Sternchen.Z. B. in Pennsylvania recycling less than half of the waste water which you produced in the 18 months, in December, ended natural gas companies, State records according to.Still, recycling has environmental and health risks. Some methods can leave salts or mud focused with radioactive materials and other contaminants that can be dangerous people to aquatic life, if you get in waterways.Some good operators are lack of supervision also sell their waste rather than to use numbers. Because so salty you ready buyers have found it in communities that need on the roads in the winter salt to spread and for dust suppression in the summer. When ice melts or is rain, the waste can run off road and at the end of the drinking Versorgung.Dennoch remains in Pennsylvania, where the number of authorisations for gas wells drilling is partially jumped significantly in the past few years, because of the State to a large underground gas formation, known as the Marcellus shale is to spread this waste of federal and supervision, also when converted into salts, and on the streets.When Pennsylvania regulators strengthen government control tried, how drilling waste water is tracked, an industry Coalition argued vehemently against it. Three of the top officials in the session state - k. Scott Roy, Barbara Sexton and j. Scott Roberts - have left since the Government for the natural gas industry."An Executive at a drilling waste water recycling company said that for all the benefits of recycling, it was not a panacea.""No one wants to admit it, but at some point, also with reuse of water, you've got to make the issue", said Brent Halldorson, Chief Operating Officer of Aqua-pure/wells quail-water management, added, having the waste water of barium, strontium and radioactive elements, which must be removed. His company is based in Roanoke in the suburb of Dallas.Halldorson stressed that he had not seen, readings in the factory, which he operates in Williamsport, Pa.More than 90 percent of the good operators in Pennsylvania use radioactivity you known this procedure as Hydrofracking, To produce well. 10 To 40 percent of the water in each well injected appears in the first weeks of Prozesses.Viele States send your drilling to injection wells for underground storage. But due to the geological formations in Pennsylvania, there are some injection wells, and other alternatives are expensive. So, for the recycling of natural gas, as well as operators have turned into the State.Defence of work "which technical breakthroughs, which lead us to the nation in water recycling a combination of onsite and offsite treatment, allows a carefully orchestrated water management system, which depending on are complemented by specific geography and economics," said Kathryn Klaber, President of the Marcellus slate Coalition, an industry trade Group.Staat and company records show that recycling reports at least 320 million gallons in the year and a half, which ended in December, well operators. But at least 260 million litres waste water plants, which treated her in the rivers, made of more than 680 million gallons of sewage waste, according to state data posted Tuesday sent. One that would extend from those of New York City to Richmond line would fill more than 28,800 tanker truck, the 260 million gallons, Va.Practice increases, while the total amount of recycling that nowhere in the State close to the 90 percent, which the industry has been claimed in the last year, the practice was certainly on the rise in recent months. The reported amount is produced about 65 percent of all recycling in the past six months, up by about 20 percent during the 12 months before. Records.Das is at least 50 million additional gallons of waste water untreated, according to State fate more wastewater is unknown due to industry lobbying. In 2009, as regulatory authorities attempted to strengthen, steadfast against the Marcellus slate Coalition the effort the supervision of the industry's practices for the disposal of their waste.
