What additional ancillary data would improve the understanding of the occurrence, sources, transport, and fate of VOCs in ground water and drinking-water supply wells?
More data on releases of volatile organic compounds (VOCs) to the air, ground surface, or vadose zone would improve our ability to understand the occurrence and sources of VOCs. Many sources of VOCs in ground water are probably small spills, such as consumer and commercial releases, and many times these releases are not reported or are stored in national databases with minimal information. More data or higher resolution data on the hydrogeologic properties of the aquifers examined, such as recharge, flowpath directions, redox conditions, and soil properties, would improve our understanding of the transport and fate of VOCs. Much of this type of data was available for the initial analysis, but in many cases the information was low resolution, was extrapolated from large-scale surveys, or was estimated from surrogate variables.
