Contamination in Fractured Rock Aquifers
Mirror Lake, N.H., located in the Hubbard Brook Experimental Forest, is the location of a research site where USGS scientists and others developed methods to characterize the groundwater flow and the transport of chemical constituents in fractured rock -- from the Mirror Lake Site

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:
Chlorinated Solvents in Fractured Sedimentary
Rock -- Naval Air Warfare Center (NAWC) Research Site, West Trenton, New Jersey
Multidisciplinary Characterization of
Contaminant Transport in Fractured Rock -- Mirror Lake, New Hampshire [Completed]
