Investigation into fracking related pollution

Fracking is in the spotlight again, as investigations into the controversial practice get underway.

The Environmental Protection Agency (EPA) has completed the first round of tests on water in 11 homes in the US town of Dimock, where residents claimed to be affected by cloudy, bad-smelling water.

The first round of 11 homes “did not show levels of contamination that could present a health concern,” a regional EPA spokesman said in an email. The tests did find sodium, methane, chromium or bacteria- but traces within safe ranges, the spokesman added.

Fracking, or hydraulic fracturing, is where large amounts of water, mixed with chemicals and sand, are blasted underground to push natural gas to the surface, potentially polluting water supplies. The practice has also caused concerns of seismic activity in some locations in the US and the UK.

Complaints first came from the residents of Dimock following nearby fracking activity by Cabot Oil & Gas Corp in 2008. In January this year, the EPA launched its series of tests on 60 homes in the area.

The studies have found arsenic in the water of two homes, but at safe levels. However, re-testing is scheduled to take place and the EPA has been delivering fresh water to several of the Dimock homes and will continue to do so for the duration of their investigations. Results are expected next week.

Cabot is pleased with the first round of results, a company spokesman revealed, adding that Cabot will continue to work with the EPA during their analysis of the area.

Fracking is claimed, by the gas industry, to be revolutionary, by allowing access to new gas reserves that could support the US for another 100 years. However, environmentalists and health groups argue that some of the operations near homes and schools have caused pollution to water and air.
