The subsurface, which extends from the soil surface through the saturated zone, is a basic component of the global ecosystem. Unfortunately, despite the essential roles played by subsurface ecosystems, it is the least characterized, quantified, and appreciated component. Determining ecosystem risk will not be possible until we quantify characteristics and activities of the subsurface component. Research will focus on determining the basic characteristics of the subsurface ecosystem with molecular techniques, and quantifying the interrelationships with other components of the global ecosystem. Emphasis will be placed on determining the species present and their community structure because of consortium involvement in xenobiotic degradation. Appropriate assessment endpoints and corresponding response, habitat, exposure, and stressor indicators will be devolved as ecocriteria. We will also quantify exchanges of gases between the subsurface and atmosphere, the exchange of chemicals to water, and the exposure limits (assimilative capacity) of the subsurface to potential pollutants.
