“…Although some aquifers are comparatively inert (chemically) in the timeframe of a MAR operation, in general there will be potential geochemical changes affecting water quality [40,41,53,54]. The chemistry of water stored in an aquifer during MAR is affected by chemical reactions, driven by the aquifer's conditions (e.g., pH, redox state, minerals, organic matter, microbial activity) and the quality of recharged water.…”

Abstract:To meet increasing urban water requirements in a sustainable way, there is a need to diversify future sources of supply and storage. However, to date, there has been a lag in the uptake of managed aquifer recharge (MAR) for diversifying water sources in urban areas. This study draws on examples of the use of MAR as an approach to support sustainable urban water management. Recharged water may be sourced from a variety of sources and in urban centers, MAR provides a means to recycle underutilized urban storm water and treated wastewater to maximize their water resource potential and to minimize any detrimental effects associated with their disposal. The number, diversity and scale of urban MAR projects is growing internationally due to water shortages, fewer available dam sites, high evaporative losses from surface storages, and lower costs compared with alternatives where the conditions are favorable, including water treatment. Water quality improvements during aquifer storage are increasingly being documented at demonstration sites and more recently, full-scale operational urban schemes. This growing body of knowledge allows more confidence in understanding the potential role of aquifers in water treatment for regulators. In urban areas, confined aquifers provide better protection for waters recharged via wells to supplement potable water supplies. However, unconfined aquifers may generally be used for nonpotable purposes to substitute for municipal water supplies and, in some cases, provide adequate protection for recovery as potable water. The barriers to MAR adoption as part of sustainable urban water management include lack of awareness of recent developments and a lack of transparency in costs, but most importantly the often fragmented nature of urban water resources and environmental management.

“…Arsenic has been measured in samples of recovered water at concentrations 5 to 10 times greater than the MCL of 10 µg/L. (31) The mobilization of arsenic during ASR could result in additional treatment costs to remove arsenic from the recovered water. Concentrations of arsenic decrease over time as additional cycles of storage and recovery deplete the arsenic in the aquifer materials.…”

Library of Congress Cataloging-in-Publication DataBerndt, Marian P.The quality of our nation's waters---water quality in the upper Floridan aquifer and overlying surficial aquifers, Southeastern United States, 1993States, --2010 ForewordThe United States has made major investments in assessing, managing, regulating, and conserving natural resources, such as water and a variety of ecosystems. Sustaining the quality of the Nation's water resources and the health of our diverse ecosystems depends on the availability of sound water-resources data and information to develop effective, science-based policies. Effective management of water resources also brings more certainty and efficiency to important economic sectors. Taken together, these actions lead to immediate and long-term economic, social, and environmental benefits that make a difference to the lives of millions of people (http://water.usgs.gov/nawqa/applications/).Two decades ago, Congress established the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program to meet this need. Since then, NAWQA has served as a primary source of nationally consistent information on the quality of the Nation's streams and groundwater, on ways in which water quality changes over time, and on the natural features and human activities affecting the quality of streams and groundwater. Objective and reliable data, systematic scientific studies, and models are used to characterize where, when, and why the Nation's water quality is degraded-and what can be done to improve and protect the water for human and ecosystem needs. This information is critical to our future because the Nation faces an increasingly complex and growing need for clean water to support people, economic growth, and healthy ecosystems. For example, NAWQA findings for public-supply wells, which provide water to about 105 million people, showed that 22 percent of source-water samples contained at least one contaminant at levels of potential health concern. Similarly, 23 perce...

“…The recharge of aquifers by oxygenated groundwaters is a common phenomenon, leading on occasion to the formation of a migrating redox front (McMahon and Chapelle, 2008). Pervasive in situ oxidation can occur when penetration is rapid, particularly in response to anthropogenic extraction of potable water (Thornberg and Sahai 2004) or injection for the purpose of aquifer storage and recovery (ASR) (Arthur et al, 2005). Such oxygenation can lead to the mobilization of heavy metals, particularly As, Cd, Pb and U, with adverse consequences to water quality.…”

“…Increasing use of aquifer storage and recovery techniques (ASR) has also lead to arsenic contamination of the recovered water (Arthur et al, 2005). A significant proportion of the sampled more than 38,000 well water samples taken from the NWIS database already possess As levels exceeding current MCLs.…”
