Summary
Site-specific water quality criteria may evolve from national water quality criteria based on site water characteristics. Suspended solids may be an important modifying parameter. A model is presented relating suspended solids characteristics (organic carbon content and suspended solids concentration) with a neutral organic chemical's sorption coefficient. Investigation of case studies with acenaphthene, dieldrin, and chrysene shows the dissolved and particulate-bound fractions (Cd and Cp) of total chemical concentration (Ct) to be dependent upon these factors. The model may be used to predict Cp and Cd in site waters. The model shows that chemicals with low Kp values in the presence of low suspended solids concentrations and organic matter are relatively unaffected by suspended solids. Conversely, chemicals with high Kp values, high suspended solids concentrations, and organic matter would be primarily sorbed to suspended solids.
