C.; Keese, Kelley E.This study aimed to estimate groundwater recharge rates for major porous media aquifers in Texas, essential for assessing aquifer vulnerability to contamination. Recharge rates were estimated through one-dimensional unsaturated flow modeling and limited field studies in the Southern High Plains and Seymour aquifers. Field studies involved measuring soil physics and environmental tracers in soil samples from boreholes in various land use settings. Numerical modeling of unsaturated flow utilized long-term climatic data, soils data, and vegetation data. Simulated recharge rates varied from 54 mm/yr in west Texas to 720 mm/yr in east Texas, positively correlated with precipitation. High recharge rates in east Texas suggest climate is not the limiting factor, with soil texture and vegetation playing crucial roles in reducing recharge. Layered soil profiles led to locally variable recharge estimates, but areally weighted averages were less variable and positively correlated with precipitation. Vegetation significantly reduced recharge rates in all cases, with simulations including vegetation and layered soil profiles resulting in recharge rates ranging from 0.2 to 114 mm/yr. The 30-year average recharge rates across simulated stations in the state were positively correlated with precipitation, suggesting long-term precipitation as a predictor of recharge. This comprehensive approach provides valuable insights into groundwater recharge dynamics, crucial for assessing aquifer vulnerability to contamination.Item Evaluation of Contamination and Remediation Manvel Saltwater Disposal Site Brazoria County, Texas(1996) Kaiser, W. R.; Paine, Jeffrey G.; Tweedy, Steven W.The Manvel Saltwater Disposal (SWD) site (RRC Site No. 92-03-00003), which lies within the city limits of Manvel, Texas, in Brazoria County, was investigated by the Bureau of Economic Geology during a 5-month study from July through November 2015. The study included hydrogeological investigation, waste characterization, assessment of environmental impact, and evaluation of remediation options. Saltwater, drilling waste, and crude oil have been disposed of at the site. There have been several instances of pit overflow, levee rupture, or both, resulting in contamination of the surrounding area by saltwater and crude oil. There have been several public complaints to regulatory agencies, centered on the perceived threat to groundwater quality. The site lies in the outcrop of the Beaumont Formation, where the formation is sufficiently thick to be a local aquifer, containing freshwater with chlorinities of less than 100 mg/L. The Beaumont lies above and is hydrologically distinct from the main water-yielding part of the Chicot aquifer.Item Fax from HRC to Mayor of Abra Pampa: Meeting with Mayor Ariel Machaca on April 30, 2009(2009-04-21) Human Rights Clinic - School of Law UT AustinItem Hydrogeologic Analysis of Contamination and Evaluation of Remediation Alternatives - Fox Vacuum Site, Jasper County, Texas(1995) Dutton, Alan R.; Paine, Jeffrey G.; Tweedy, Steven W.The Bureau of Economic Geology (BEG) investigated the Fox Vacuum site (RRC Site No. 93-03-0019) in Jasper County, Texas, during a 4-month study from July through October 1995. Historical aerial photos indicate the site was developed between 1958 and 1976. Contamination identified at the start of this study included a sulfuric-acid contamination plume (soil pH of 1 to 4) that had affected the quality of soil water and killed grass across approximately a one-half-acre (2,023-m²) area of an adjacent pasture. The site also was believed to have seven earthen pits, probably containing spent drilling mud. The depth of the acid contamination was unknown. The scope of the BEG study was to determine the source, present extent, and probable fate of the sulfuric acid contamination and to ascertain the volume and contents of the earthen pits. This report presents the results of that study, along with an environmental impact assessment, risk-based evaluation of cost-effective remediation alternatives, and recommendations for RRC action.Item Intendente de Abra Pampa elogia al Gobierno(2008-07-23) El LibertarioItem Interesado, Defensor del Pueblo, Dictamen, March 29, 2007(2007-03-29) Vitti, Jeronimo; Maiztegui, Cristina
