Contamination in Fractured Rock Aquifers
Fractured-rock aquifers are widely distributed near land surface and are highly susceptible to contamination from human activities. Researchers are developing an improved understanding of the movement of water and contaminants in fractured-rock aquifers, methods for characterization of field conditions, and modeling tools. Contaminant transport and fate is fundamentally different in fractured rock than in unconsolidated (sand and gravel) aquifers. Significantly more uncertainty exists as to the direction and rate of contaminant migration, as well as the processes and factors that control chemical and microbial transformations. At many contaminated sites across the Nation, remedial action is delayed or stymied by the complexity of contaminated fractured-rock aquifers. Long-term research on contamination in fractured-rock aquifers has been conducted at the Program’s two field research sites: Other Program Fractured Rock Research
