The 1996 amendment to the Safe Drinking Water Act of 1974 created the Source Water Assessment Program (SWAP) with an objective to evaluate potential sources of contamination to drinking water intakes. The development of a Source Water Assessment Plan for Las Vegas Valley surface water runoff into Lake Mead is important since it will guide future work on source water protection of the main source of water; Once the vulnerability of the intake was determined, a tool was developed to help with source water assessment, using the system dynamics model Stella. This model calculates the average vulnerability of the intake, given the four factors (PBE, risk potential, TOT, and water quality). It was tested with the data obtained in the Nevada SWAP, but it is applicable to any other area; The model was then used to evaluate the possibility of the major road crossings impacting the drinking water intake; Finally, the model was modified so it can be used for assessing accidental spills at locations near storm channels.
