Assessing Mercury and Organic Contaminants in the Guadalupe River: A Comprehensive Study
This study focuses on mercury loads, methylmercury concentrations, and organic contaminants in the Guadalupe River, detailing small tributary sampling and suspended sediment loads conducted by a multidisciplinary team. Analyzing data from water years 2003 to 2005, the report presents findings on total mercury, bedload mercury concentrations, and organic contaminant loads. The project outlines a timeline and future research prospects, including the potential impacts of management strategies on mercury transport processes, ensuring comprehensive data quality and accessibility for ongoing monitoring efforts.

Total Mercury Loads 133% MAQ 111% MAQ 96% MAQ
Methyl Mercury Loads • 40 g or 0.5% of total Hg load
Bedload Mercury Loads • 1% of total Hg load
Organic Contaminants WY 2003 WY 2004 WY 2005
Project Schedule • WY 2005 • Report completed read for review • WY 2006 funded by USACE/SCVWD / RMP • Complete QAQC for all WYs and get the data on the WWW • Write papers for Journal • WY 2007 funded? • Only WY 2006 currently guaranteed but everything in place for continuation • RMP funding not yet discussed • Future Modeling (if funding is found)? • Explore transport processes in more detail • Explore and predict the effects of management on Hg loads
