density tests were performed primarily with nuclear gauge (Troxler) and corrected using oven r moistures. Exploratory Borings 1 We drilled and sampled six exploratory borings to depths of 35 and 40 feet to better understand the conditions which exist within the refuse pile. Sampling was performed with Shelby tubes or mod~ed California-type samplers. Logs of the borings are contained in Appendix A. ~ During drilling we observed the upper 20 feet of the fill was much wetter than lower materials. The driller attempted to identify when he had drilled into the wet layer and also when he drilled out of it by how stiff the material would drill. We had difficulty recovering samples within a depth of 20 feet in most of the boring because of the high moisture within this portion of the refuse. The water did not allow for samples to stay within the Shelby tubes or the California sampler during extraction from the hole. We found the wet zone was relatively consistent throughout the fill. We recorded it as shallow r/ as nil feet and at depths up to 21 feet. Below the wet layer of fill, the coal refuse was comparatively dryer and samples were easily obtained. This fill was found to be dense to very dense and moist to ~ very moist. Piezometers ~ We placed piezometers at various depths within the fill in an effort to confirm if the wet layer was confined to the top 21 feet of the fill and if it is draining. We installed piezometers at four depths; 10 feet (Boring 104), 24 feet (Boring 107), 54 feet (Boring 106) and 69 feet (Boring 103). The bottom five feet of each pipe was slotted to allow water to infiltrate the pipe at these depths. The pipe was • placed within the hole as a continuous section and the bottom five feet was backfilled with loose coal refuse from the surface. We then placed 4.5 to 8 feet of bentonfte pellets to limit drainage from the 3 •
