The Alfred Merritt Smith Water Treatment Plant (AMSWTP) supplies 85% of the required
drinking water for the Las Vegas Valley. The potable water supply for the AMSWTP is Lake
Mead, which is part of the Colorado River system. Four major waterways carrying untreated
urban runoff from the Las Vegas Valley enter into Lake Mead via the Las Vegas Wash.
Recognizing that the valley's urban runoff is a nonpoint source of pollution to the potable water
supply the AMSWTP initiated a pathogen virus monitoring program from November 2000 to
November 2001. The strategy of this program was to sample the 4 waterways on a monthly basis
and then analyze the samples by a combined ICC-RT-PCR method. The targeted viruses were
those already being monitored for in Lake Mead: enterovirus; hepatitis A virus; norovirus
genotype I and II and group A rotavirus. Sample processing methods, elution and concentration,
established during the virus ICR study, were also used. Results from the project revealed that in 9
of the 12 months during the project period either rotavirus or enterovirus was detected. Also, all of
the waterways during the testing produced positive results for rotavirus or enterovirus. Neither
hepatitis A virus nor norovirus was detected during this time period. Includes 20 references, tables, figures.
