Activist shareholder groups are pressing natural gas companies to reduce the environmental impact of a drilling technique called hydraulic fracturing.

The investor groups say they have filed resolutions with nine oil and gas companies that use hydraulic fracturing, or "fracking," to extract gas from shale formations thousands of feet underground. Critics contend that fracking has the potential to pollute groundwater. The industry says it is safe.

The shareholder proposals ask drillers to explain how they plan to manage the risks associated with fracking. The shareholders also want full disclosure of fracking chemicals, a reduction in the volume and toxicity of the chemicals, improvements in well construction and related measures.
