Abstract: Depleted uranium has been found at a number of live-fire training ranges across the United States as a result of test firing the Davy Crockett System. This weapon system was fielded from 1961 through 1971 and was capable of launching a small-yield nuclear war-head. Only the spotting rounds (20-mm spotting M101) were used in Hawaii. Fifteen surface-water samples and three duplicate samples were collected from six significant storm events to indicate the presence or absence of depleted uranium in the Makua valley. The activity of the various isotopes was measured by the laboratory for 234U, 235U, and 238U; and then conversions from picocuries of activity to milligrams of uranium were calculated. Laboratory results of surface-water samples from Makua Military Reservation showed that no depleted uranium was leaving the reservation. Uranium concentrations in surface water reported by the analytical laboratory are indicative of naturally occurring uranium.
