The thrust of this project is the development of better techniques for characterizing contaminated sites. Objectives include the development of better computational methods for the detection and assessment of groundwater contamination and the determination of the mechanisms and parameters which govern the transport and fate of pollutants at field scales.

Summary/Accomplishments (Outputs/Outcomes):

There is seldom enough information to determine with certainty the precise values of all parameters for characterizing a contaminated site, especially at the local scale. Measurements of some critical transport parameters, such as hydraulic conductivity, indicate variability over orders of magnitude over short distances. Other parameters, such as thermodynamic constants and rate coefficients, are quite variable too. In many cases, however, determination of the "effective" parameters of the heterogeneous formation, i.e., those which govern the net or "macroscopic" rate of advection, dispersion, and chemical attenuation, rather than the highly variable local rates, is sufficient and is what is sought by this study.

The developed approach combines measurements, mechanistic models describing the transport and fate of pollutants, and statistical methods. In recognition of the spatial variability of geologic formations and incomplete knowledge of their properties, the parameters which determine the transport and fate of solutes, such as conductivity, retardation, and reaction coefficients, are characterized in statistical terms. The mathematical formalism of random functions is used to describe spatially variable quantities through statistical moments, such as mean and covariance functions. These moments are obtained from data and other (such as geological) information using geostatistical techniques. Then, through the governing flow and mass transport equations, the statistics of solute concentration are determined. These methods are applied to two problems of practical interest: the evaluation of the macroscopic, or field-scale, flow and transport parameters and the conditioning of predictions on measurements.

Initial efforts focused on the determination of the relation between the measurable but highly erratic local parameters and the effective parameters which govern the flow and solute transport at macroscopic scales of interest. The second year produced a numerical spectral method for carrying out computations of interest. Project complete.
