End Notes
1Value derived from the EqP method with Region III marine values (2004a) and logKow values from Karickhoff and Long (1995b). Only logKow values between 2 and 6 were used, as suggested by the EPA (2000 g).
2Currently no marine sediment value is available. Refer to US EPA Region 3’s Freshwater Sediment Screening Benchmark table for a value.
3Threshold Effect Level.
4Interim Sediment Quality Guideline.
5Consensus-based Threshold Effect Concentration.
6Original value 290ug/gOC, 1% organic concentration, value converted to 2.9ug/g dry wt = 2.9mg/kg dry wt.

Hierarchy for Selection of Marine Sediment Benchmarks
- Preference was given to benchmarks based on chronic direct exposure, non-lethal endpoint studies designed to be protective of sensitive species
- Values derived by consensus-based evaluation of multiple studies for marine or estuarine waters were given first priority
- Values derived by statistical-based evaluation (TEL) of multiple studies for marine or estuarine waters were given second priority
- Equilibrium partitioning values were selected for contaminants with 2.0< log Kow <6.0 if empirical values based on multiple studies were not available
- Absent consensus or equilibrium partitioning values, single study toxicity values were selected
- Absent a value in the table, a freshwater sediment value can be used if available
