The safe disposal of fly ash from power plants remains a concern because of dwindling available disposal sites and potential or actual environmental consequences. During the period from 1957 to 1974, the Virginia Electric and Power Co. station at Yorktown used a mixture of coal and refinery coke for power generation. The fly ash and bottom ash byproducts were disposed of in borrow pits which drain into Chisman Creek, a small estuary near the York River. In 1980 a domestic well near the pits turned green and tests revealed high concentrations of V and Se in some wells. Subsequently, contaminated wells were capped and homes were connected to the municipal water supply.
In late 1981 with a small.grant from the Virginia Environmental Endowment, we began a more detailed investigation of possible contamination from the pits. The sampling program included groundwater, surface water, estuarine water, flyash, soils near the pits, oysters and a variety of plants in the immediate vicinity. Most importantly, these samples were analyzed by PIXE (Proton-Induced X-Ray Emission), a sensitive and accurate multielemental technique which can simultaneously detect all elements from silicon to uranium without prior knowledge of the elements present.
