Objective:

Nearly all natural processes are either cyclic or episodic, yet laboratory efforts to simulate fate and transport are almost always steady state column or batch experiments. If the mechanisms of contaminant fate are fundamentally linear (not necessarily first order) and reversible, then there are well established mathematical procedures to model the impact of cyclic or episodic (e.g., a single or stepped spike, etc., events) variations. Unfortunately, many natural processes of importance to contaminant fate are non-reversible as they occur in lakes, streams, and estuaries. It will be shown that these non-reversible processes are expected to have previously unexpected and profound impacts on the fate of common contaminants in natural systems of particular importance to the Gulf Coast HSRC regions. Commonly recognized processes that are known to change over scales of space and time of interest to modeling include: temperature, salinity, pH, redox potential, and oxygen tension. The overall objective of this research will be to develop model procedures and equations which can be used to predict the effects of changes in natural environmental variables on slow, or resistant, desorption and long-term clean-up.

Progress Summary:

Considerable progress has been made on this project to date. The limits of changes in pH, temperature, salinity, and redox conditions on desorption of hydrophobic organic compounds from the irreversibly sorbed compartment have been studied systematically in order to set the ranges and probable effects for cyclic variations of these variables. Temperature has been varied from 5 to 50 C; pH has been varied from about 6 pH (limited by the solubility of carbonate minerals in the actual sediments) to 14 pH; and redox effects have ranged from highly anoxic (pE @ -4 to -5) in the presence of sulfides to fully aerobic, with pE @ +13. For most of these conditions either kinetics or estimates of rate have also been determined. Together, these critical variables will be put into standard mathematical models of varying boundary conditions to aid in contaminant fate modeling. This project has supported three Ph.D. and one M. S. students. One of the Ph.D. student, Wei Chen, has contributed numerous papers and presentations. Dr. Chen has received his Ph.D. degree in September, 1999. Due to his contribution to this project, he has received an outstanding graduate student award from the Department of Environmental Science and Engineering, Rice University.

Future Activities:

The research will focus in developing a risk-based model. Remediation clean-up standards have moved toward site-specific, risk-based levels. To determine the site-specific levels, models may be used to assess the risk at a site and calculate the required clean-up concentrations. However, sorption/desorption processes assumed in the risk models are typically the simple linear isotherm, which was the origin of the inability to accurately model the contaminant level at a specific site. Work will be done in this area to incorporate the irreversible adsorption isotherm developed at Rice University (Kan, et al., 1998) to several public domain or commercially available risk models, such as the Groundwater Services Inc. (GSI) Risk-Based Corrective Action (RBCA) tool kit, EPA's MMSOILS, Department of Energy (DOE) MEPAS, General Science Corporation's SESOIL, and the Air Force's BIOSCREEN. Simulation will be done using these modified risk models to compare the model results with field data. A field database, such as the Florida Risk-Based Corrective Action (RBCA) Planning Study consisting of data from 117 sites, may be available for comparison; the Florida RBCA database and other field data will be available to the proposed researchers through GSI. Dr. Newell, the Vice President of GSI and Adjunct Professor at Rice University, will serve on the Graduate Student Research Committee to advise in this area.
