Download or read book Water Quality Changes During Cycle Tests at Aquifer Storage Recovery ASR Systems of South Florida written by and published by . This book was released on 2004 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water-quality changes were interpreted from existing cycle test data obtained from 11 treated surface-water Aquifer Storage Recovery (ASR) systems located in South Florida. Six ASR systems are located along the lower east coast (Palm Beach and Broward Counties), and five ASR systems are located in Lee and Collier Counties. These diverse data sets were the basis for interpretations of water-quality changes during ASR cycles in different regions. These data sets were interpreted to provide guidance for cycle test performance at Comprehensive Everglades Restoration Plan (CFRP) ASR pilot sites. ASR and monitoring well data were interpreted for trends in water-quality changes. Estimates of reaction rates or half-lives are based only on data obtained from monitoring wells during storage. Analytes that are reactants or products in major geochemical reactions are: dissolved oxygen, nitrate and ammonia, sulfate and hydrogen sulfide, gross alpha radioactivity and radium isotopes, and total trihalomethanes. Concentrations of these solutes in recovered water samples from recharge/recovery wells were compared to state and Federal water quality regulations to identify regulatory exceedences. Concentrations of arsenic and gross alpha in recovered water sometimes exceeded regulatory criteria at ASR sites in Southwest Florida.

This book was released on 2015-06-10 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Florida Everglades is a large and diverse aquatic ecosystem that has been greatly altered over the past century by an extensive water control infrastructure designed to increase agricultural and urban economic productivity. The Comprehensive Everglades Restoration Plan (CERP), launched in 2000, is a joint effort led by the state and federal government to reverse the decline of the ecosystem. Increasing water storage is a critical component of the restoration, and the CERP included projects that would drill over 330 aquifer storage and recovery (ASR) wells to store up to 1.65 billion gallons per day in porous and permeable units in the aquifer system during wet periods for recovery during seasonal or longer-term dry periods. To address uncertainties regarding regional effects of large-scale ASR implementation in the Everglades, the U.S. Army Corps of Engineers (USACE) and the South Florida Water Management District conducted an 11-year ASR Regional Study, with focus on the hydrogeology of the Floridan aquifer system, water quality changes during aquifer storage, possible ecological risks posed by recovered water, and the regional capacity for ASR implementation. At the request of the USACE, Review of the Everglades Aquifer Storage and Recovery Regional Study reviews the ASR Regional Study Technical Data Report and assesses progress in reducing uncertainties related to full-scale CERP ASR implementation. This report considers the validity of the data collection and interpretation methods; integration of studies; evaluation of scaling from pilot-to regional-scale application of ASR; and the adequacy and reliability of the study as a basis for future applications of ASR.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the issues that have been encountered at other sites, and the steps that have led to successful resolution of these issues, can provide great help to those considering, planning, or implementing new groundwater recharge projects. Recent technical advances and operational experience have demonstrated that well recharge is a feasible and cost effective method of artificially recharging natural aquifers. This practical guide reviews the technical constraints and issues that have been addressed and resolved through research and experience at many sites. The book presents aquifer storage recovery (ASR) technology and traces its evolution over the past 25 years in the United States. Procedures for groundwater recharge are presented, and selected case studies are examined. Drinking water quality standards and conversion factors are provided in the appendix for easy reference.

This book was released on 2001-03-09 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquifer storage and recovery (ASR) is a process by which water is recharged through wells to an aquifer and extracted for beneficial use at some later time from the same wells. ASR is proposed as a major water storage component in the Comprehensive Everglades Restoration Plan (CERP), developed jointly by the U.S. Army Corps of Engineers (USACE) and the South Florida Water Management District (SFWMD). The plan would use the Upper Floridan aquifer (UFA) to store as much as 1.7 billion gallons per day (gpd) (6.3 million m3/day) of excess surface water and shallow groundwater during wet periods for recovery during seasonal or longer-term dry periods, using about 333 wells. ASR represents about one-fifth of the total estimated cost of the CERP. Aquifer Storage and Recovery in the Comprehensive Everglades Restoration Plan examines pilot project from the perspective of adaptive assessment, i.e., the extent to which the pilot projects will contribute to process understanding that can improve design and implementation of restoration project components. This report is a critique of the pilot projects and related studies.

This book was released on 2005 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements in a number of water-quality parameters (e.g., disinfection by-products [DBPs], DBP precursors, and microbes) have been observed as a result of aquifer storage and recovery (ASR) of drinking water. The mechanisms of this improvement, which include chemical, physical, and biological processes, are not well understood. As a result, regulations governing injection of water into aquifers do not take into account these processes and may be unnecessarily restrictive. Further, utilities are unable to accurately predict and plan for water quality improvements during ASR. This project will characterize the water quality improvements realized through ASR and develop a method for estimating them.

This book was released on 2003-01-16 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report reviews a comprehensive research plan on Everglades restoration drafted by federal and Florida officials that assesses a central feature of the restoration: a proposal to drill more than 300 wells funneling up to 1.7 billion gallons of water a day into underground aquifers, where it would be stored and then pumped back to the surface to replenish the Everglades during dry periods. The report says that the research plan goes a long way to providing information needed to settle remaining technical questions and clearly responds to suggestions offered by scientists in Florida and in a previous report by the Research Council.

Download or read book Quantifying Water Quality Changes During Managed Aquifer Recharge in a Physically and Chemically Heterogeneous Aquifer written by Carlos Descourvieres Joiko and published by . This book was released on 2011 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] In many parts of the world, depleting water resources and their management are recognised as a fundamental problem. The impact of this problem is enhanced by seasonal as well as long-term imbalances between fresh water supply and demand. Managed aquifer recharge (MAR) is increasingly used to mitigate these imbalances. MAR operations often involve the injection of oxic waters into anoxic media, which will generally trigger a wide range of mineral dissolution/precipitation, ion exchange and complexation reactions that can alter the water quality. However, while the influence of physical heterogeneity on MAR processes is increasingly recognised, little attention has been devoted to the superposed impact of physical and geochemical heterogeneity on water quality. A comprehensive series of experiments, at both laboratory and field scale, were conducted in the context of a pilot aquifer storage and recovery (ASR) implementation in Perth, Western Australia, to develop a quantitative understanding of the coupled physical and hydrogeochemical processes that affect the quality of the recovered water. In the first part of this study a detailed aquifer characterisation was carried using high-resolution sediment sampling. The minerals that were likely to act as reductants for the oxygen introduced by the injection water and participate in the redox chemical reactions during a MAR operation were identified and quantified. These minerals included: pyrite, sedimentary organic matter (SOM), Fe(II)-carbonates and Fe(II)-silicates. The sediment characterisation was used in conjunction with incubation experiments to investigate correlations between reactive and physical parameters of the aquifer material. Subsequently, long-term batch and column experiments were performed to quantify the kinetics of the reactive processes that emerge under MAR conditions. The different contributions of the reductant and of the different lithologies to the oxygen consumption measured during sediment incubation experiments were quantified. This geochemical characterisation showed that grain size fractionation and hydraulic sorting were the main controlling processes that determined the geochemical signature of the sediments. The aerobic reductive capacity, as defined by the rate of oxygen consumption, was found to be dependant on the reductant concentration but also on the variability in reductant composition and availability...

This book was released on 2016-08-09 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is an investigation of the feasibility of an aquifer storage and recovery project using the existing water supply infrastructure of the city of Millville, Utah. The project involved injecting water from a public water supply spring into a public water supply well. Geochemical analysis indicates that the major ion chemistry of the spring water is very similar to that of the principal aquifer, however, the spring water would likely cause minor geochemical changes in the groundwater due to oxidation. The study also showed that the injection well had elevated nitrate concentration which is likely due to septic systems in the area. Overall, the pilot tests showed that injection of water for storage would not be detrimental to the principal aquifer, which has significant storage abilities beyond the capacity of Millville’s water system; however elevated nitrate in the aquifer is a problem that should be addressed.
