We have modeled chemical transport in sediments in both coastal and river environments, including:

Sediment cap performance assessments (sand caps and AquaBlok caps) involving diffusion and tidal pumping-induced advection and dispersion
Modeling and negotiation support for a Monitored Natural Recovery remedy
Estimation of chemical attenuation factors between groundwater wells and shallow porewater in sediments

Grant Carey of Porewater Solutions has been participating on the ITRC Contaminated Sediments team and is one of the instructors for the ITRC web seminar entitled: Remedy Selection for Contaminated Sediments.
