Results were correlated from the Microtox assay and the whole effluent acute toxicity test for effluents from the (1) wastewater treatment plant (WWTP) and (2) terminal ponds located at the Rocky Flats Plant. Literature reviews indicate that Photobacterium phosphoreum (Microtox assay) may be used as screening test for the reaction of Ceriodaphnia dubia and Pimephales promelas to toxins present in effluents. This study indicates that the Microtox is less sensitive to toxins present in the WWTP effluent than other test organisms (Ceriodaphnia dubia and Pimephales promelas). Toxicity appears to be from unionized ammonia. Ten months of data reveal that the surface water effluents which leave Rocky Flats boundaries are non-toxic when judged by all three test organisms.
