This book was released on 2013 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater pumping from the Sparta aquifer in Union County, Arkansas, has long exceeded natural recharge, threatening the regional water supply. An alternative water-supply project, completed in 2004, now provides treated surfacewater to local industries. This conjunctive use of surface- and groundwater has allowed the Sparta aquifer to recover somewhat. Exploring further possibilities for Union County, the author has evaluated the potential of artificial recharge by well injection. A MODFLOW groundwater model was modified to simulate the aquifer's response. to artificial recharge. Results indicate that artificial recharge in this context is impractical. Injection increases hydraulic heads only locally, with the most improvement occurring where the injection is located in an existing cone of depression in El Dorado, Arkansas. Since groundwater withdrawals are already concentrated in this area, injection only reduces the net withdrawal rate. The same result could be achieved by reducing or substituting groundwater withdrawals directly, as has been observed since the completion of the alternative-supply project. The modeling results, along with analyses of surfacewater resources, suggest that continued and expanded conjunctive use is the most viable water-management strategy in Union County.

This book was released on 2013 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sparta aquifer in Union County, Arkansas has served as an important potable water supply to the public and industrial sectors in the area. However, increasing water demand and sustained heavy pumping from the aquifer has resulted in the formation of major cones of depression in the area. Union County has been declared as one of the five "critical groundwater areas" in Arkansas due to rapid water level declines, salt water intrusion and overall withdrawals exceeding the rate of natural recharge. To mitigate the adverse impacts of a depleted aquifer, Aquifer Storage and Recovery (ASR) by well injection at the center of the cone of depression is evaluated to address the issue. ASR is the injection of potable water into an aquifer for storage and recovery for use when needed. One important aspect in successful design and operation of ASR systems is to assess the potential geochemical reactions between the injected water and the local aquifer water, which are typically of very distinctive compositions and environmental conditions. The goal of this paper is to use the geochemical modeling software PHREEQC to simulate the scenario of injecting partially treated surface water from Ouachita River into the Sparta aquifer at the city of El Dorado. Key reactions modeled include the initial mixing of the two waters in the proximal zone, surface exchange reactions of the major cations, iron precipitation/ dissolution reactions and the oxidizing potential of the injection water. Results from the modeling indicate that reducing the oxygen content of the injection water to enhance geochemical compatibility with the anoxic aquifer water would be beneficial. Arsenic dissolution or attenuation could occur depending on the mixing ratio of injection water to groundwater. Oxidation of ferrous ions is modeled to illustrate the oxidizing potential of the mixed water in the aquifer and the potential of iron precipitation is assessed.

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.
