Book Site Observational Work Plan for the UMTRA Project Site at Shiprock New Mexico

Download or read book Site Observational Work Plan for the UMTRA Project Site at Shiprock New Mexico written by and published by . This book was released on 1994 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The site observational work plan (SOWP) for the Shiprock, New Mexico, Uranium Mill Tailings Remedial Action (UMTRA) Project Site is the initial document for developing site-specific activities to achieve regulatory compliance in the UMTRA Ground Water Project. The regulatory framework used to select the proposed ground water compliance strategies is presented along with a discussion of the relationship of this SOWP to other UMTRA Ground Water Project programmatic documents. The Shiprock site consists of two, interconnected hydrogeologic systems: the terrace system and the floodplain system. Separate compliance strategies are proposed for these two systems. The compliance strategy for the terrace aquifer is no remediation with the application of supplemental standards based on classification of the terrace aquifer as having Class III (limited-use) ground water. The compliance strategy for the floodplain aquifer is active remediation using a subsurface biological barrier. These strategies were selected by applying site-specific data to the compliance framework developed in the UMTRA Ground Water programmatic environmental impact statement (PEIS) (DOE, 1994a). The site conceptual model indicates that milling-related contamination has impacted the ground water in the terrace and floodplain aquifers. Ground water occurs in both aquifers in alluvium and in fractures in the underlying Cretaceous age Mancos Shale. A mound of ground water related to fluids from the milling operations is thought to exist in the terrace aquifer below the area where settling ponds were in use during the mill operations. Most of the water occurring in the floodplain aquifer is from recharge from the San Juan River.

Book UMTRA Project Site Observational Work Plan Mexican Hat Utah

Download or read book UMTRA Project Site Observational Work Plan Mexican Hat Utah written by and published by . This book was released on 1994 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface cleanup activities at the Mexican Hat UMTRA processing site are nearing completion. Ground Water contamination at the Mexican Hat site is a result of uranium milling operations. The extent of residual process water has been identified, and it is limited to the uppermost aquifer in the vicinity of the site. Deeper aquifers are not affected because of an upward hydraulic gradient and the presence of a confining unit (the deeper aquifers are protected by hydrogeologic isolation). The uppermost unit is returning to its pre-milling, mainly unsaturated state. The unit that contains the contaminated water is not a ground water resource because it qualifies as Class III (limited use) based on limited yield. Ground water in the uppermost unit is currently not used and is not anticipated to be used as a ground water resource. The nearby San Juan River and a converted oil exploration well provide all of the water needs for the area. There are no current threats to human health or livestock; and, because the zone of contamination does not represent a ground water resource, none are anticipated in the future. There are, however, seeps where contaminated water is exposed at land surface. The seeps create potential exposure pathways for plants and wildlife. It is not known at this time if there is a risk to the environment. Additional investigations are needed and are described in this document to confirm the presence or absence of potential environmental risks. Additional hydrogeologic investigations are not required. The proposed ground water compliance strategy for the site is no remediation, because the ground water in the uppermost aquifer (which is also the zone of contamination) qualifies for supplemental standards based on Class III, limited yield, and because there are no threats to human health. Domestic and agricultural water is pumped from a deeper aquifer that is isolated from the contaminated zone.

Book Wheatland and Lancaster County

Download or read book Wheatland and Lancaster County written by and published by . This book was released on 1890 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The beginning of this scrapbook focuses on Lancaster County's history, historic locations, and places such as the Horse-Shoe Trail, Conestoga Valley, Columbia, and Wheatland in Lancaster County. Other locations in Pennsylvania that are referenced are Valley Forge, Manada Gap, and Wrightsville. The volume contains newspaper clippings that recall the historic event known as the Burning of the Columbia-Wrightsville Bridge. Some articles of interest portray historical occupations and the indentured servants that served in those occupations throughout Lancaster. There is also information on Robert Fulton and his birthplace located in Southern Lancaster County. The latter half of the scrapbook describes the history of Wheatland and James Buchanan. Several newspaper clippings reveal the development of Historic Wheatland and the excavation of the property. The articles also discuss the opening of the site to the public.
