Book excerpt: Master's Thesis from the year 1998 in the subject Environmental Sciences, The University of Texas School of Public Health, language: English, abstract: This project investigates the transport of sediment and associated contaminants through the lowerportion of the Rio Grande/ Rio Bravo International Watershed. A preliminary review of water quality, bed sediment, and reservoir sediment-coring data in the watershed reveals a complex hydrological system, with varying potential sources of contamination. Within the lower portion of the watershed (defined as from the dams at Elephant Butte Reservoir in New Mexico and Red Bluff Reservoir in Texas co the Gulf of Mexico) arsenic, lead, and mercury appear at levels and/ or trends which may be of concern. Through the use of a geographic information system, this project evaluates the extent of contamination from selected toxic substances, identifies potential sources and/ or naturally-occurring conditions for the contribution of these toxic substances, and evaluates the potential for using Geographic Information Systems to model the watershed. The project uses data collected over the thirty year period from 1966 - 1996 by the Texas Natural Resource Conservation Commission, the United States Geological Survey, the International Boundary and Water Commission, and the United States Environmental Protection Agency. The project utilizes water quality, bed sediment, sediment coring, land use, land cover, soils, water-quality permitting, precipitation, flow, and reservoir-release information to attempt to derive a model depicting the movement of sediment through the watershed. Because the United States federal government has not promulgated standards for sediment (as of 1998), the project references standards from both the State of Washington and Canada for screening of sediment quality.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical hydraulic mining activities in the Yuba River watershed have impacted the watershed and the San Francisco Bay. The research evaluates pathways for mercury entry into the watershed and potential remediation technologies to reduce the risk of future mercury contamination from hydraulic mining debris. Remediation technologies for the Yuba Goldfields and Englebright Reservoir are discussed and compared separately. The major pathway for mercury entry into surface water along Yuba Goldfields is within suspended sediment mobilized during flooding conditions. While multiple remediation options are available for the Yuba Goldfields, phytostabilization is the least costly and has the fewest environmental impacts. A non-profit organization is currently working on a restoration project attempting to increase vegetation cover in areas with hydraulic mining debris, creating the potential for synergy in remediation and restoration goals and effort. A phytostabilization pilot study is recommended along the Yuba Goldfields as well as additional characterization of mining debris deposited within the Yuba Goldfields. The major pathway for mercury entry into surface water along Englebright Reservoir is from methylation of mercury in shallow sediments and subsequent movement of methyl mercury into the surface water. Within the Englebright Reservoir, aqueous capping is currently the most promising technology that allows mercury contaminated sediments to remain in place while removing ability for mercury to methylate. An aqueous capping pilot study within Englebright Reservoir and additional characterization of sediments within the reservoir are recommended.
