Passive sampling methods for contaminated sediments: Risk assessment and management
This paper details how activity‐based passive sampling methods (PSMs), which provide information on bioavailability in terms of freely dissolved contaminant concentrations (Cfree), can be used to better inform risk management decision‐making at multiple points in the process of assessing and managing contaminated sediment sites. Because Cfree is a better predictor of bioavailability than total ...

Application of passive sampling for measuring dissolved concentrations of organic contaminants in the water column at 3 marine superfund sites
Currently, there is an effort under way to encourage remedial project managers at contaminated sites to use passive sampling to collect freely dissolved concentrations (Cfree) of hydrophobic organic contaminants to improve site assessments. The objective of the present study was to evaluate the use of passive sampling for measuring water column Cfree for several hydrophobic organic ...

Land Treatment
Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate ...
