A major interest of the U. S. Environmental Protection Agency has been the assessment or ranking of vulnerable water utilities. Until recently, no techniques have been available that quantitatively put into perspective the many often conflicting factors that contribute to a utility's vulnerability to point and nonpoint sources of pollution. A methodology is described, using two case studies, that enables such analyses and also closes the information gap that potentially exists between water pollution control strategies and water consumption.
