Interest in hydraulic conductivity of soils and waste contaminant transport has increased substantially in recent years, largely due to environmental concerns. Assessments of potential contamination at a site are possible only if accurate information is available concerning the hydraulic conductivity of subsoils.
STP 1142 provides this information, including detailed coverage of methods for determining the hydraulic conductivity of soil in the laboratory and in the field. This publication describes testing methods, test results, and case histories. Applications include water, chemical, and leachate movement through soil.
28 peer-reviewed papers cover:
Methods for determining hydraulic conductivity of saturated soils in the laboratory
