National Resource Defense Council (NRDC) List of Suspected Drinking Water Impacts (2011)

NRDC supports federal regulation of hydraulic fracturing under the Safe Drinking Water Act. We believe this is a sensible approach that would ensure a minimum federal floor of drinking water protection in the more than 30 states where oil and gas production occurs.

Opponents of such regulation claim that hydraulic fracturing has never caused any drinking water contamination. They say this because incidents of drinking water contamination where hydraulic fracturing is considered as a suspected cause have not been sufficiently investigated, either because scientists and regulators could not properly investigate (did not have the information or technology needed) or because they chose not to, even where signs point to hydrauliac fracturing. Some cases where groundwater was contaminated during hydraulic fracturing operations have been attributed to other causes, such as faulty well structure, even if a well failed during the hydraulic fracturing process.
