Abstract

The purpose of this study was to predict zones of protection around drinking water wells in an effort to limit ground water contamination from viruses. Seventy-one water samples were collected from wells in the Tucson basin. The samples were inoculated with MS-2 phage and the decay rates of the virus with time were determined. Kriging, a geostatistical method which analyzes data based on its spatial arrangement, was employed to estimate decay rates at point for which no samples were taken using known values obtained at nearby wells. Using the kriged values for virus decay rates and the characteristics of ground water flow in the Tucson basin, a map of the area was constructed which delineates zones around drinking water wells within which potential sources of ground water pollution should not be placed to ensure the absence of viruses in the wells.
