A company hired to perform a groundwater study in southern West Virginia for the Department of Environmental Protection admits it made an error.
Triad Engineering says one of 33 samples taken from the communities of Seth and Prenter in Boone County exceeded DEP standards for lead in drinking water.
The DEP said Wednesday in a release that the agency and the engineering company accidentally overlooked the result. The DEP says it plans to contact the owner of the well and let him aware of the finding.
DEP officials say the study still shows no evidence of widespread groundwater pollution related to mining.
But a lawyer for 350 residents suing coal companies over water pollution says the study is fundamentally flawed and calls the DEP a shill for the coal industry.
