DNAPL site evaluation. Research report
Dense nonaqueous-phase liquids (DNAPLs), especially chlorinated solvents, are among the most prevalent subsurface contaminants identified in ground-water supplies and at waste disposal sites. There are several site-characterization issues specific to DNAPL sites including: (a) the risk of inducing DNAPL migration by drilling, pumping or other field activities; (b) the use of special sampling and measurement methods to assess DNAPL presence and migration potential; and (c) development of a cost-effective characterization strategy that accounts for DNAPL chemical transport processes, the risk of inducing DNAPL movement during field work, and the data required to select and implement a realistic remedy. The manual provides information to address these issues and describes and evaluates activities that can be used to determine the presence, fate and transport of subsurface DNAPL contamination.
