This 2019 Sustainable LA Grand Challenge Water Report Card for Los Angeles County provides an in-depth look at the region’s efforts to move toward a more resilient local water supply. This requires maximizing high-quality local water supplies, improving water conveyance and treatment infrastructure, reducing water consumption, and implementing innovative technology and policy solutions.
Researchers looked at 20 indicators across eight categories: water supply and consumption, drinking water quality, local water infrastructure, groundwater, surface water quality, industrial and sewage treatment plant discharges, water-energy nexus, and beach water quality. The grades range from D/ Incomplete to B+, and although there has been great progress in some areas, others still require significant improvement to raise the county’s C+ average.
