A front end loader picks up coral to be used to build berms at the Tanapag project's containment cells. The berms help contain the PCB-contaminated soil.

Workers place heavy plastic sheeting over a load of PCB-contaminated soil to keep it in place. The sheeting was covered at the edges by clean material to ensure the sheeting remained on top of the soil.

Graves in Tanapag's Cemetery No. 2, site of the PCB-remediation project

A containment cell showing the heavy plastic sheeting that goes both beneath and on top of the excavated and collected PCB-contaminated soil.

Excavation of soil at the Cemetery No. 2 site.

Sites were restored with clean material after PCB-contaminated soil was excavated. Before the material was placed, soil sampling was done at each site to ensure it was in compliance with the 1 part per million or less environmental standard for the project.

After clean material was placed, heavy equipment smoothed and compacted it to aid the restoration process
