Demonstrators who oppose a form of shale gas exploration are planning to march to the building where North Carolina lawmakers may soon decide whether to allow the procedure in the state.
Members of environmental groups planned to gather Saturday in a Raleigh park and march to the Legislative Building.
Hydraulic fracturing is also called fracking. It involves injecting a drilled well with chemically treated water and sand to crack shale rock and free trapped natural gas.
The state environment department says fracking can be conducted safely if lawmakers adopt the right precautions. Opponents argue the threat of tainted groundwater isn't worth the risk.
Croatan Earth First, the Cumnock Preservation Association, and the Blue Ridge Environmental Defense League are participating in the march.
