Summary: Water supplies are critical to urban populations in southern California. These supplies and the associated ecosystems are impacted by residents' decisions with respect to water conservation, pollution prevention, and landscape plants.
Completed Projects Estimating soil nitrogen mineralization for fertilizer management Due to high groundwater nitrate concentrations, California growers are facing increasing pressure to improve nitrogen use efficiency in crop production to reduce nitrate leaching.
Summary: The Salton Sea, the largest lake in Southern California, provides critical wildlife habitat. While it was once part of a vast inland sea, more recently water in the lake has come largely from irrigation runoff and leaching.
Summary: California uses approximately 15 billion gallons of groundwater per day, more than any other state in the United States. Currently, groundwater accounts for about half of Californias water supply.
Summary: Street-side stormwater management facilities are increasingly common as cities try to find ways to increase local water recharge. These facilities are often planted with vegetation that includes ornamental trees. However, little is known about the survival, growth, and health of the trees.
Summary: Methylmercury is found in low or no oxygen environments and can be toxic to wildlife at low levels. Studies from the Yolo Bypass in the Sacramento-San Joaquin Delta suggest that rice systems may be a significant source of methylmercury in the Delta.
Summary: High-volume hydraulic fracturing is a relatively new and controversial form of natural gas and oil drilling that is poised for a boom in California. This type of fracking is water-intensive and could exacerbate water stress.
