My take is it to early to determine what caused the problem. It may have been a release of chemicals in the ground that the drilling upset. If that’s the case clean it up and take more precautions and have the state EPA follow this more closely. In fact don’t these EPA guys suppose to check the site every couple of weeks? Are they doing their jobs?
This is private property owned by the drilling company, why should these environazis be allowed to fly over it and take pictures?
