Multivariate geostatistical analysis of groundwater contamination by pesticide and nitrate

Creator:: Smyth, Jeffrey D.
Abstract:: A field study was conducted to determine the applicability of multivariate geostatistical methods to the problem of estimating and simulating pesticide concentrations in groundwater from measured concentrations of nitrate and pesticide, when pesticide is undersampled. Prior to this study, no published attempt had been made to apply multivariate geostatistics to...

Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

Assessing groundwater vulnerability to contamination using finite element modeling and geographic information systems

Creator:: Rea, Alan H.
Abstract:: A method was developed for assessing the vulnerability of groundwater to contamination from contaminant sources at the soil surface, using a numerical groundwater flow model linked to a digital map database. The method was applied using the pcARC/INFO Geographic Information System (GIS) to input, store, and manipulate base maps, resulting...

Precipitation estimation in mountainous terrain using multivariate geostatistics

Creator:: Hevesi, Joseph A.
Abstract:: Estimates of average annual precipitation (AAP) are-needed for hydrologic modeling at Yucca Mtn., Nevada, site of a proposed, high-level nuclear waste repository. Historical precipitation data and station elevation were obtained for stations in southern Nevada and southeastern California. Elevations for 1,531 additional locations were obtained from topographic maps. The sample...

A kinetic model for dissolved gas transport in the presence of trapped gas

Creator:: Donaldson, Jeremy H.
Abstract:: Understanding the processes involved in the transport of dissolved gas plumes in groundwater aquifers is essential for comprehending the effect that these transport processes can have on site characterization and remedial design applications. Previous laboratory and field studies have indicated that dissolved gas transport in groundwater can be greatly affected...

A numerical model for the fate and transport of chlorinated phenols in groundwater

Creator:: Lee, Sang Bong
Abstract:: The objective of this study was to develop a numerical model for the movement and fate of chlorinated phenols in groundwater. In the first part, a numerical model for several different equilibrium and nonequilibrium sorption processes under isothermal conditions is developed for one-dimensional, steady-state water flow in soil columns. The...

Groundwater flow model for the lower Malheur Basin near Ontario, Oregon

Creator:: Walker, David S.
Abstract:: The shallow, poorly-confined, sand and gravel aquifer underlying the lower Malheur River basin is contaminated by nitrate and metabolites of the herbicide dimethyl tetrachloroterephthalate (DCPA), first detected in 1983 and 1985, respectively. The aquifer supplies water for the Ontario municipal water system, domestic and industrial uses, and irrigation. In response...
