Geostatistics Applied to Groundwater Contamination. II: Application

This paper presents an application of the procedures developed in the first paper in this series (Cooper and Istok 1988) to measured values of groundwater contaminants at the Chem‐Dyne toxic waste site located in Hamilton, Ohio. Six contaminants were studied: boron, barium, iron, manganese, zinc, and TVOC. Experimental semivariograms were computed for each contaminant and were fitted by combinations of pure nugget effect and linear and spherical semivariogram models. Point kriging was performed on the log‐transformed contaminant densities, and maps of the estimated contaminant densities and the kriging variances were drawn.
