The chemical fractionation/aquatic bioassay test basically involves biological testing, first using a given collection of leachate, surface water, or liquid waste, and then using fractions and subfractions of the original sample material. The final test result, derived from a compilation of these different bioassay responses, is used to identify bioactive fractions of the original sample material, to assess some of the additive, synergistic and/or antagonistic effects caused by the component waste chemicals, and to provide a preliminary (or screening) hazard evaluation for the aquatic ecosystem. While the procedure has been successfully used for monitoring industrial pollutants, the overall technique was not considered to be ready for use at hazardous waste sites. Results from an initial evaluation indicated that procedural revisions were necessary to improve the chemical fractionation phase. When these procedural revisions had been made, another evaluation was conducted using samples taken from actual hazardous waste sites.
