Integrated Science and Management of Nutrient, Salt, and Mercury Export from San Joaquin River Wetland Tributaries to the Delta

Description / purpose

Mercury, salinity, and nutrients such as nitrogen and phosphorus are major contaminants of concern and are an understudied source of water quality impairment to the Delta. This study will (1) examine seasonal variation and transfer of salt, nutrients, and mercury out of managed wetlands;(2) establish and verify whether other routinely monitored water components can serve as reliable alternatives (proxies) for detecting mercury and nutrients;(3) integrate monitoring data and proxy relationships to estimate levels of contaminants;and (4) develop science-based strategies for adaptive co-management of salt, nutrients, and mercury from seasonal wetlands to improve water quality in the Delta. Outcomes from this study will provide improved best practices and guidelines for management of salt, nutrients, and mercury in wetlands. Results will also address key knowledge gaps identified in the Delta Nutrient Research Plan and provide support for the Delta Mercury Control Plan.
