Abstract:
Water systems are responsible for conducting monitoring of drinking water to ensure that it meets all drinking water standards. EPA has established pollutant-specific minimum testing schedules for public water systems. Typical sampling and monitoring sites in distribution systems may include points close to water treatment systems, core business locations, secondary water storage reservoirs, repumping or retreatment facilities and change in water quality. Sampling location is also dependent on investment in labor, transportation requirements, and supplies to carry out sampling commitments. This adds to a water utilities financial commitment. Monitoring and/or predicting the fate and transport of introduced contaminants in water distribution systems is therefore a challenging proposition, involving the identification and operation of numerous hydrological and water quality-related factors. A common and important question in the design of a monitoring network is how many samples should be collected and where? The answer is often based upon best professional judgment and financial considerations. This paper describes a methodology to select nodes for monitoring in case of an intrusion. The monitoring location selection methodology uses a combination of extended period simulation (EPS) model and GIS data.
