As some residents call for the closure of Bristol, Virginia’s landfill, two firms in charge of reducing odors from the landfill are giving an update saying the 21 wells to be installed by Friday will significantly help the situation.Representatives from Draper Aden Associates and SCS Engineers believe that recently added gas wells could help reduce the odors.“We have every expectation that this will substantially reduce the amount of fugitive odors that are being released,” Ernie Hock of Draper Allen Associated told the City Council.
