In May 2008, Josh Fox received a letter from a natural gas company offering to lease his family's land in Milanville, Pennsylvania for $100000 to drill for gas.[1] Following the lease offer, he looked for information about natural gas drilling in the Marcellus Shale under large parts of Pennsylvania, New York, Ohio and West Virginia. He visited Dimock, Pennsylvania where natural gas drilling was already taking place. In Dimock, he met families able to light their tap water on fire as well as suffering from numerous health issues and fearing their well water had been contaminated. Fox then set out to see how communities are being affected in the west where a natural gas drilling boom has been underway for the last decade. He spent time with citizens in their homes and on their land as they relayed their stories of natural gas drilling in Colorado, Wyoming, Utah and Texas, among others. He spoke with residents who have experienced a variety of chronic health problems as well as contamination of their air, water wells or surface water. In some instances, the residents are reporting that they obtained a court injunction or settlement monies from gas companies to replace the affected water supplies with potable water or water purification kits.[2]
