The Municipal Water Quality Investigations Program: A Retrospective Overview of the Program’s First Three Decades
This paper presents the history and evolution of the California Department of Water Resources’ Municipal Water Quality Investigations (MWQI) program. This program tracks source water quality in the Sacramento–San Joaquin Delta (Delta) for drinking water supply for nearly two-thirds of California. Th...
