Task 3.2 Test Pits Three test pits will be excavated into the ash fill at the site to depths of 6 to 8 feet below grade utilizing a rubber-tired backhoe. As the test pits are excavated, in-place density tests will be performed. Bulk samples will be obtained for testing in the laboratory. Following completion, the test pits will be backfilled in

into the test cavity. Residual volatile organic compounds (VOCs) and metals from two drilling mud pits could not be removed effectively and safely. Both mud pits are below the shallow water table under concrete or covered with clean fill. One mud pit is located at surface ground zero; the other is located nearby.

must be developed. For example, for test pitting at the toe, if critical gradient piping is a concern, materials to stop progressive erosion in the trench must be ready. For this situation, it is recommended to stockpile fine (C33 concrete sand) and coarse processed aggregates and geotextiles at or near the site to filter and plug the excavation.

For samples requiring the use of heavy equipment (i.e. back-hoe, loader) to excavate, samplers should not enter the pit/trench. All observations and samples can generally be taken from the excavated material at the ground surface. "Trenching and excavation work presents serious risks to all workers involved.

test pits and drilling operations. The proposed locations of test pits and boreholes are presented on Figure 1. 3.1 Test Pits An excavator or backhoe is proposed to excavate six test pits within the vicinity of the pond. The purpose of these test pits is to determine if seepage is occurring into the shallow subsurface from the ponds.

TEST PIT EXCAVATION AND FIELD SCREENING Thirteen test pits were excavated during the release investiga- t ion, using the PGC backhoe. Test pit locations are shown on Plate 2 and were selected to ascertain the presence of and assess the extent of contamination. Photographs from the release investigation are displayed on Plates 3 through 10.

* Soil and rock sample collection Collecting samples of soill and rock from natcral exposures, hand-dug pits, quarries, roadcuts, drill holes, and backhoe trenches. * Laboratory testing Geotechnical testing of soil and rock specimens. Emphasis was placed on tests that characterize tunnel conditions.

the outset, it seemed likely that a 20-30 percent sample of the midden could be recovered by the end of the project. Fortunately, this proved to be far short of what eventually was achieved. During the spring of 1977, the site was mapped and two 1-x-2-m test pits were dug to begin determining the depth of the midden.

and to obtain representative samples for chemical characterization. Although 52 test pits were originally planned, four of these test pits were not completed as the locations fell at the center of the South Return Water Trench (RR-TP-24 and RR-TP-48) or the existing railroad track (RR-TP-14 and RR-TP-15). The test pit locations were focused on the
