2005 Annual Self-Monitoring Report - Eden Landing

This annual self-monitoring report summarizes the results of the water quality monitoring and sediment sampling conducted at the Baumberg Complex, also known as the Eden Landing Ecological Reserve (ELER), in Hayward, California, April through November 2005. Data was collected by the U.S. Geological Survey (USGS) on behalf of the Department of Fish and Game (Department) in accordance with the waste discharge requirements. Water quality monitoring was performed using continuous data recorders at the locations described in the Self-Monitoring Program outlined in the Final Order, except Pond B10. B10 had discrete monthly “grab” samples, as requested by the Department and approved by the Regional Water Quality Control Board (RWQCB) staff in June 2005, as described in its letter to the Department dated October 5, 2005. Water column sampling for metals was performed using following Environmental Protection Agency (EPA) method 1669 (Sampling ambient water for trace metals at EPA water quality criteria levels), and dissolved mercury samples were analyzed using EPA method 1631. Analysis of the 2005 sediment samples will be forwarded to the RWQCB staff under separate cover, after completion of analysis since paired sampling seasons will include data collected in the 2005/2006 winter season.
