Trench covers are generally much more permeable than the natural material or liners below the waste, and both cover and liner play an important role in controlling moisture movement through the waste. Trench Covers Trench covers, which are critical to minimizing moisture move- ment through the waste, were almost ignored until a few years ago, although careful attention has been given to landfill .

    Study of trench covers to minimize infiltration at waste disposal sites. Task II report. Laboratory tests were conducted on geologic mateials selected for use in covers for waste disposal sites: the materials included fine-grained loess and glacial till, used in covers and liners for waste disposal sites, and various coarse-grained.

In many instances trench caps are specifically designed to promote lateral flow. Clay layers or native soil amended with bentonite, as proposed for the Ward Valley B/C trench covers, are used to minimize downward water movement. Clay soil barriers are generally wetted and compacted to achieve permeabilities of approximately cm/s. In arid.

The property encompasses approximately acres, including a buffer zone of acres of adjacent land. The site is located in the. The sites must be carefully designed and engineered to minimize differential compaction that may occur, and trench covers must be constructed to con- trol infiltration so that it is equal to or less than the possible migration rate from the site.

Four experimental waste disposal trench covers were constructed to test the effectiveness of layered-soil cover designs in reducing infiltration.

Three covers each consisted of a layer of gravel. CavcriSaxou^ IL6cr ISGSCONTRACT/GRANTREPORT ASTUDYOFTRENCHCOVERSTOMINIMIZE INFILTRATIONATWASTEDISPOSALSITES.
