Report for European Commission on Environment -"Because of the health and environmental risks, the study recommends that fracking should only be allowed under strict conditions, and not yet on an industrial scale. No fracking should be allowed in areas where water is being used for drinking purposes."
There is scientific proof that hydraulic fracturing regularly contaminates drinking water supplies. This occurs for groundwater and aquifers, and with fracturing fluid and hydrocarbons.
Other effects of hydraulic fracturing are too numerous to list. Case studies indicate that hydraulic fracturing is detrimental to communities in innumerable ways.
