A conceptual ground-water-quality monitoring network for San Fernando Valley, California

Abstract

A conceptual (ideal) ground-water-quality monitoring network was developed for San Fernando Valley to provide the California State Water Resources Control Board with an integrated, basinwide control system to monitor the quality of ground water. The geology, occurrence and movement of ground water, land use, background water quality, and potential sources of pollution were described and then considered in designing the conceptual monitoring network. The network was designed to monitor major known and potential point and nonpoint sources of ground-water contamination over time. The network is composed of 291 sites where wells are needed to define the ground-water quality.The ideal network includes four specific-purpose networks to monitor (1) ambient water quality, (2) nonpoint sources of pollution, (3) line sources of pollution, and (4) point sources of pollution.
