Fate and transport of contaminants in the environment
Understanding and modeling of processes leading to exposure and riskIn-situ approaches to intervention in these processes to manage that risk
Media of interest – contaminated sediment
Passive sampling of interstitial water concentrationsSediment capping/amended capping/permeable sorptive barriers
