ERAS performed a Phase 1 project that identified oil filled underground quenching pits used by a former metal foundry that operated on the Property. The buyer wanted to convert the former industrial facility to a live work residential development. A Phase 2 project was designed that included drilling of soil borings inside the building to assess the subsurface for the presence of contamination. Analysis for a variety of possible contaminants of concern was conducted. Contamination was reported to the Alameda County Health Care Services Agency (ACHCSA), who subsequently provided regulatory oversight.

Additional borings were subsequently drilled to delineate the lateral and vertical extent of contamination for the purposes of remediation. A Remedial Action Plan was submitted to the ACHCSA. After approval, approximately 3,000 cubic yards of soil was excavated and disposed. Confirmation soil sampling by ERAS indicated that contamination was successfully removed over the entire inside of the building. A small area of contamination remained in one area that was under the adjacent residential properties. The ACHCSA provided written approval for the planned construction activities within approximately 18 months of the initiation of the project.
