- The freely dissolved concentration (Cfree) of a hydrophobic organic contaminant in sediment is a better predictor of bioavailability than the total concentration in bulk sediment.
- Passive sampling methods (PSMs) that target Cfree reduce uncertainty in site investigations by characterizing spatial and temporal contaminant trends, source contributions, calibrating models, and improving weight-of-evidence based decision frameworks.
- PSMs can help delineate sediment management zones, assess remedy effectiveness, and evaluate risk reduction following management action.
- Cfree can be used to better inform risk management decision making.
