This unique publication provides a global perspective on one of the most complex issues in hydrology: field and laboratory measurement of low permeability and dual porosity materials. Eleven peer-reviewed papers, written by an international group of experts, focus on the development of techniques to evaluate hydraulic conductivity and remediation of fine grained and dual porosity geologic materials.

It deals with a range of issues related to the measurement of both 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, environmental scientists, waste management personnel, landfill owners and operators, and remediation specialists.
