Description DDT and/or its breakdown products DDE and DDD were detected in seven of twelve Okanogan River/Lake Osoyoos tributaries sampled in July - August 1995. Concentrations substantially exceeded the state chronic surface water quality standard of 0.001 ug/L (parts per billion) in Tallant Creek (0.19 - 0.50), Nine-Mile Creek (0.0054 - 0.0064) and an un-named creek in Omak (0.0055 - 0.0080). Except for Tallant Creek, these concentrations are similar to other state waters contaminated with DDT from historical use.
