Project Overview
A testing
and monitoring program was initiated at the Prototype Hanford Barrier
in October 1995. This new project will use the unique facilities
provided by the prototype barrier to establish an adequate record
of long-term performance and to demonstrate and evaluate techniques
capable of monitoring performance of field-scale covers. This work
builds on the 10 years of experience at Hanford that culminated
in the construction of a full-scale, instrumented, research cover
over an existing waste site. Many of the monitoring technologies
employed at the Hanford Barrier are also applicable to measurement
of hydraulic and transport properties in the vadose zone. Thus,
capitalizing on this existing cover for the studies proposed herein
represents significant cost savings to the DOE's barrier development
program. The work in this proposal will complement existing programs
at other sites and satisfy the technology development needs identified
by Hanford STCG for FY2000 and beyond.
