Dover Air Force Base - Dover, DE
The main challenges faced at Dover Air Force Base (DAFB) were a major environmental cleanup effort, reduced funds to accomplish the job, and resistance to using new technologies. Use of cleanup technology demonstrations, at the expense of the technology vendors, could resolve the first two problems but would run head on into the last challenge. This challenge could only be overcome by educating those opposed to using new technologies. This was not a one time effort. It required repeating the same message over and over until it began to sink through the shield of "It won't work at Dover". Another tactic to gain acceptance of new technologies was the implementation of small demonstrations that were out of the way, out of sight, and caused no long term impact.
Three major demonstrations are fully implemented and a forth is nearing implementation. Five smaller demonstrations have been completed. The National Test Site has been approved with the first test cell in place and the first permitted controlled release complete. The test to cleanup the first release of JP-4 jet fuel and trichloroethene (TCE) solvent is underway. Other test cells are being planned with associated controlled releases. The second is planned to start the last of September 1996.
The cleanup of the largest groundwater solvent plume was estimated to cost $90 to $100 million using the best available, accepted technology. The current estimate for the cleanup of the plume after the demonstrations are complete is $5 million, to cleanup what the demonstrations do not finish off (using a less expensive technology proven by the demonstrations). The net savings is in excess of $85 million. Additional demonstrations are planned for the remaining contaminant plumes on base, which will increase savings.
Benefits to DAFB include reduced cleanup costs due to better technologies, and reduced cleanup quantity necessary after the demonstrations.
