Clean up crews working on the Cooper River Oil Spill are concentrating their efforts today on the remaining heavily concentrated areas of recoverable oil between Piers Delta and Pier Papa on the Old Navy Base in Charleston. Contractors will also be replacing saturated absorbent boom with new absorbent boom to facilitate collections efforts. To date, more than 700 gallons of oil has been recovered using skimmers, absorbent pads and boom. The spill still remains a mystery but more than 100 people from 10 different federal, state and local agencies are aggressively working to clean up the oil spill. Presently, over $225,000 has been spent on the recovery effort and the ceiling for the clean up was raised from $500,000 to $750,000 today.
