Development and promulgation of sediment quality criteria represents a substantial challenge for water quality agencies. Unlike water quality programs that rely on individual chemical thresholds to assess water quality, the complex processes affecting contaminant bioavailability in sediments preclude the use of contaminant concentrations to independently assess impacts or identify cause. Variou...

The most common reason for improved decision making is the mere fact that the information reduces uncertainty. In basic terms, the greater the uncertainty in information, the less valuable that information becomes as a guide to future actions. Despite these seem...
