CHEMICAL METHOD OF PREVENTING LOSS OF INDUSTRIAL AND FRESH WATERS FROM PONDS,LAKES AND CANALS1

Preventing or markedly reducing the loss of aqueous fluids from a variety of reservoirs is becoming increasingly important. Fear of pollution from industrial waters and sewage impoundments as well as the economic factors involved in loss of fresh water add impact to this problem. This paper reviews the seriousness of the problem and methods that have been used to reduce loss of fluid are discussed. New materials for control of water loss are constantly being advocated, and chemical research has provided new systems that work extremely well. These systems, which combine unique chemicals and novel methods of application, are described. Specific case histories are also included.
