The Water Replenishment District of Southern California (WRD) is the largest groundwater management agency in the State of California, with a 420-square mile service area that encompasses 43 cities and four million residents in southern Los Angeles County. WRD manages the Central Basin and the West Coast Basin (CBWCB) which comprise approximately 50% of the geographic area and 53% of the population of the Los Angeles-Orange County coastal plain aquifer system, part of the California Coastal Basins aquifers. WRD was created in 1959 to address the problem of severe groundwater overdraft and seawater intrusion in Los Angeles County, and in that role, has been monitoring groundwater in the Central Basin and West Coast Basin (CBWCB) for over 50 years. During this time, WRD has been actively involved in groundwater replenishment, water quality monitoring, contamination prevention, data management, and data publication. WRD's Regional Groundwater Monitoring Program currently consists of a network of more than 320 monitoring wells at 58 locations throughout the District. WRD has a dedicated Board of Directors and professional staff that engage in year-round activities to closely monitor groundwater conditions. WRD collects, analyzes, and reports on groundwater data to ensure proper resource management.

Principal aquifers monitored are part of the California Coastal Basins aquifer.

 

Current NGWMN Projects

2018: 7/1/2018 to 6/30/2021

Project to become a new data provider to the NGWMN. They will provide persistent data services in year two. The Water Replenishment District of Southern California will be proving both water-level and water-quality data. 

2019: 9/24/2019 to 3/23/2022

Project is to provide persistent data services, perform site maintenance work, and to drill a well to fill a gap in the NGWMN. Well Maintenance work is to perform slug testing at all current wells and to do site improvements at 8 wells. The new proposed well is in a groundwater recharge zone and will be completed in 6 zones.
