SEWAGE DISCHARGES FROM SHIPS TRANSITING COASTAL SALT WATERS

A number of aspects of the discharging of non-oily wastewaters by transiting ships are treated. Options to discharging (the use of holding tank, onboard treatment) and the impact of changing regulations are discussed. Assessment of the effects of sewage discharges on coastal waters required that data, at first not available, be generated. An account is given of the characterization of navy shipboard wastewaters and of experiments involving sewage discharges at sea, measurements of water quality before, during, and after an amphibious operation, and fore and aft of transiting navy ships. A better understanding of sewage dilution after discharge led to the verification of a method for controlled discharging of sewage (and other wastewaters). This method permits limiting the coliform bacteria count in the ship's wake to values below acceptable limits. Information is given on long-range effects of ships' sewage discharges, obtained in studies by the USN and others, as well as public health considerations.
