Potential for containation of groundwater at Hunte

In 1985 there was flood in Marlinton WV that generated tons of hazardous waste from the stores in Marlinton, pesticides,herbicides, (?)
All of this flooded waste was loaded on trucks and hauled to the OLd Huntersville Dump which was a big sinkhole that locals used as their disposal before laws came into effect that regulate potential harm to the ground water. My concern is has this waste leached into the ground water over the years?
