Fractured Bedrock

Strategic Environmental Research and Development Program project ER-2533 In chlorinated-solvent-contaminated fractured-sedimentary-rock aquifers, low-permeability (low-K) strata typically act as long-term or secondary sources of contamination to mobile groundwater in the high-permeability fractures. The fate of dissolved trichloroethene (TCE) in the low-K matrix is controlled by abiotic...

Contaminants associated with industrial, airport, and other activities are present in groundwater in fractured-rock aquifers, posing long-term hazards to drinking-water supplies and ecosystems. The heterogeneous character of fractured rock challenges our understanding, monitoring, and remediation of such sites.

A groundwater bioaugmentation field experiment, conducted by U.S. Geological Survey (USGS), Geosyntec Consultants, Inc., and University of Toronto, Canada, scientists, demonstrates the effectiveness and potential weaknesses of this cleanup technology and provides guidance for improved design of bioaugmentation in fractured-rock aquifers. The experiment also demonstrates the benefits of advanced...

Few studies have evaluated or compared contaminant mass removal by Pump-and-Treat (P&T), Monitored Natural Attenuation (MNA), or Enhanced Biodegradation (EB) in fractured-rock aquifers, partly because of the perceived hydrogeologic complexity, the lack of understanding of the processes controlling the migration and transformation of contaminants, and the lack of sufficient field data for...
