Army tanks left over are now being used already with the leadership of the Delaware Department of Natural Resources and Environmental Control. Currently those tanks are being used as artificial reefs for fish habitats. All of the used army tanks are being cleaned thoroughly. After cleaning, all of them are being sunk and all that will float are removed. If there will be any hydraulic fluid oil or grease and contaminant, they are already being cleared, as well as those items that will obstruct the smooth flow of the water. Majority of those sunken materials are stainless steel. This process is being done hoping to increase resident fish populations.
