This unique publication provides a global perspective on one ofthe most complex issues in hydrology: field and laboratorymeasurement of low permeability and dual porosity materials. Elevenpeer-reviewed papers, written by an international group of experts,focus on the development of techniques to evaluate hydraulicconductivity and remediation of fine grained and dual porositygeologic materials.

It deals with a range of issues related to the measurement ofboth saturated and unsaturated geologic materials, including:

• Test Procedures

• Laboratory and Field Evaluations

• Low Permeability Environments and Remediation Issues

STP 1415 is a valuable resource for geologists, hydrologists,hydrogeologists, environmental and civil engineers, environmentalscientists, waste management personnel, landfill owners andoperators, and remediation specialists.
