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...

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...
