Health Consultation: Dimock Groundwater Site, Carter Road and State Route 3023, Dimock, Susquehanna County, Pennsylvania
Agency for Toxic Substances and Disease Registry (ATSDR) Centers for Disease Control
[State Impact Pennsylvania] A federal public health report on Dimock’s much-publicized water woes found threatening levels of chemicals in 27 private water wells, and explosive levels of methane in 17 private water wells during a six-month period in 2012. The results were based on samples taken four years ago, while a moratorium on hydraulic fracturing in the area was in place. The chemicals include cancer-causing levels of arsenic in 13 wells. Other substances include potentially toxic levels of cadmium, copper, iron, lead, lithium, manganese, potassium, sodium and 4-chlorophenyl phenyl ether.
The report, a “health consultation” by the Agency for Toxic Substances and Disease Registry (ATSDR), which is part of the Centers for Disease Control, looked at data from 64 private drinking water wells and also found an immediate risk of explosion in five homes due to high levels of methane in their water, and potential threats to another 12 homes. None of the information is new to the resident’s themselves, who each received a toxicology report from the EPA and ATSDR back in 2012. Some residents requested and received visits by federal researchers and experts at the time to explain the results.
The report does not analyze current water samples, and makes no conclusions about the status of the well water today. It does not identify the source of these chemicals, some of which could be naturally occurring. The authors of the report say some issues with the water-quality remain, but this is most likely the result of anecdotal information from residents themselves, not new data…
