Details

This is an original press photo. Helicopter drops one of two huge experimental aeration units, developed by the Union Carbide Corporation, into Lake Waccabuc here. Submerged 45-feet to the bottom of the lake the aerators will oxygenate the waters in an attempt to stop or reverse eutrophication of the lake. Lake Waccabuc is roughly one of 800,000 lakes in the U.S. said by environmentalists to be decaying, victims of casual pollution caused by suburbanization. The basic idea of the aerators is to keep the oxygen in the lowest layers of the lake where it does the most good, and to maintain a thermal stratification, or separation of the cold bottom waters and the warmer top water.Photo measures 8.5 x 10inches. Photo is dated 07-07-1973.
