Reviews and evaluates field methods used to study ground-water contamination. 30 peer-reviewed papers examine:

• ground-water sampling and sampling in unsaturated soils

• well-drilling (construction and monitoring)

• geophysical exploration

• quality assurance

• soil permeability

• and nonpoint source investigations.

Some case histories are included: for hydrologic engineer, hydrogeologists, soil scientists, and geotechnical engineers.
