On May 1985, a Biological Monitoring Program was developed for East Fork Poplar Creek (EFPC) in eastern Tennessee, United States. This stream originates within the Oak Ridge Y-12 Plant that produces nuclear weapons components for the Department of Energy. Water and sediment in the stream contain metals, organic chemicals, and radionuclides from releases that have occurred over the past 45 years. The creek also receives urban and some agricultural runoff and effluent from the City of Oak Ridge's Wastewater Treatment Facility (WTF). The biological monitoring program includes four major tasks: (1) ambient toxicity testing: (2) bioaccumulation studies; (3) biological indicator studies; and (4) ecological monitoring of stream communities, including periphyton, benthic macroinvertebrates, and fish. Biological conditions are monitored at six sites on EFPC ranging from kilometer 24.4 near the headwaters to kilometer 6.3 near the month. A site on Brushy Fork, A stream just north of Oak Ridge, is used as reference. Ambient (instream) toxicity was monitored through the use of 7-day static-renewal tests that measured the survival and growth of fathead minnow (Pimephales promelas) larvae and the survival and reproduction of a microstrustacean (Ceriodaphnia dubia). Full-strength water from EFPC within the Y-12 Plant boundary was frequently toxic to Ceriodaphnia, but less frequently toxic to the minnow larvae. Chlorine has been identified as an important toxicant in upper EFPC. Water samples from six sites in EFPC downstream from the Y-12 Plant boundary were tested eight times with both species during a 2-year period (October, 1986 through October, 1988). These sites were ranked by the number of times they were best'' or worst'' for each species. Water samples collected for use in the ambient toxicity tests were routinely analyzed for conductivity, pH, alkalinity, hardness, total residual and free chlorine, and temperature.
