Water contamination is a big concern in some industries, and corporations engaged in activity that causes pollution to water sources have a social responsibility to clean up their act and reduce their waste and contamination contributions. There are also legal responsibilities for companies as well. At the federal level, for instance, there is the Clean Water Act, which has the purpose of preventing water pollution by holding companies accountable. States also have their own protections against contamination which must be followed. While the federal Clean Water Act is an important means for protecting water sources, there are other federal laws addressing groundwater contamination.
One industry which is generating a fair amount of concern over water contamination at present is the natural gas industry which is using hydraulic fracturing to access resources. Fracking is the process of drilling and injecting fluids deep into the ground at high pressure to force shale rocks to open and release natural gas reserves.
