Ground-water discharges into dry docks no. 1, 2, 3, 4, 5 and 6 of Puget Sound Naval Shipyard in Bremerton, Washington equalled 0.07, 0.30, 0.29, 0.61, 1.18 and 6.2 cubic feet per second during one set of measurements in the summer of 1994. Total drainage-water discharges from the dry docks equalled 0.07, 0.30, 0.33, 0.61, 1.36 and 11.7 cubic feet per second. Differences between the two sets of discharges were cofferdam and floodgate leakages into the dry docks, and in dry dock no. 6, cooling- water discharge from a ship in dry dock. Concen- trations of total copper and total lead at 36 sampling sites in the drainage systems ranged from less than 1 to 71 micrograms per liter and less than 1 to 44 micrograms per liter, respectively. Concen- trations of all 43 semi-volatile organic compounds analyzed for in samples from 19 sites were less than the laboratory minimum reporting level (5 or 10 micrograms per liter). Trichloroethene and at least three other volatile organic compounds were found at concentrations greater than 0.2 micrograms per liter in samples from all eight sites that were analyzed for 63 volatile organic compounds.
