These pits were discovered when a foul odor indicated that a sewage line had accidentally been connected to the Monastery pit. The sewer line was disconnected. The next step was to map out all lines entering and exiting the site as seen in the figure below.

After finding all connections between the pits, three borings were drilled to obtained soil. The soil was then transported back to the lab for testing and classification. An auger is seen below completing one of the bore holes.
