* Fifty 5-gallon oil containers with a quarter containing residual amounts of oil. The condition of the oil containers that were excavated have all been compromised by being crushed, dented, and/or punctured.
* Two metal drums and one poly drum with no labels and at this time their contents, if any, are unknown.
* 20 empty non-chlorinated aerosol brake cleaner cans.
* 24 lead-acid batteries.
* Large concrete slabs with rebar from foundation of former chicken coop along with other construction debris.
* The chassis of a three wheeler, two engine blocks, a lawnmower, a water pressure tank, and a couple of bicycles.
The containers have been intermixed with household appliances and garbage which constitute the bulk of the debris excavated.
