The RAW proposes the excavation and off-site disposal of approximately upto 2,429 cubic yards of impacted soil from Areas 3 and 5. Soil would be removed from several irregularly-shaped areas to depths ranging from 0.5 feet to 10 feet below ground surface (bgs) to address soil impacted with arsenic, lead, dieldrin, PAHs, and dioxins/furans and soil gas impacted with chloroform. The area of soil removal is approximately 22,064 sf. Should soil containing chemicals of concerns above the site-specific cleanup goals remain after excavation is complete institutional controls will be placed to protect the students, staff and visitors to the high school.
