The overall objective of this project is to evaluate the effect of synthetic slurries on groundwater quality. The objective of Phase I, however, was to conduct a comprehensive literature survey (this report) to gather data to evaluate the effect of the WSDOT approved synthetic slurries on groundwater quality. Since chemical and bioassay information exists for only two products and the analyses were performed in 1991 and 1998, it is our recommendation that the slurries currently being used by WSDOT contractors be tested again for priority pollutants and toxicity. New testing would result in a consistent data set as all samples would undergo the same, most recent EPA protocol. Analysis should be performed on samples that are representative of field conditions (at the working concentration and containing any additives). The results would be used to assist in evaluation of potential groundwater contamination as well as slurry disposal issues.
