One of the Hanover Board of Supervisors' chief priorities on its legislative agenda for the 2015 General Assembly session is to ask the state Department of Environmental Quality to study the potential health risks and environmental impacts of applying industrial sludge on land in Hanover. "We're going to oppose any permit until we're convinced that there are standards in place that specifically address industrial sludge," said Sean Davis, chairman and Henry District supervisor, in a recent interview.
