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

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.

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.

Excavation Sample Size: A Cautionary Tale

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.
