The EPA and its water deliveries are leaving Dimock. The EPA announced today that it had delivered final test results to all homes, including to the 4 for which it had been supplying replacement water.
The press release states in part: "...EPA has determined that there are not levels of contaminants present that would require additional action by the Agency." http://yosemite.epa.gov/opa/admpress.nsf/0/1A6E49D193E1007585257A46005B61AD.
EPA sampling was conducted at 64 private water wells in Dimock. EPA goes on to say: "Overall during the sampling in Dimock, EPA found hazardous substances, specifically arsenic, barium or manganese, all of which are also naturally occurring substances, in well water at five homes at levels that could present a health concern. In all cases the residents have now or will have their own treatment systems that can reduce concentrations of those hazardous substances to acceptable levels at the tap."
The press release provides no information about methane levels and comes notably not on a Friday during the afternoon.
