Economics of Managed Aquifer Recharge
Managed aquifer recharge (MAR) technologies can provide a variety of water resources management benefits by increasing the volume of stored water and improving water quality through natural aquifer treatment processes. Implementation of MAR is often hampered by the absence of a clear economic case for the investment to construct and operate the systems. Economic feasibility can be evaluated usi...
متن کاملConditions in Agricultural Headwater Streams
11 Whilst the processes involved in the cycling of dissolved phosphorus (P) in rivers have been 12 extensively studied, less is known about the mechanisms controlling particulate P concentrations 13 during small and large flows. This deficiency is addressed through an analysis of large numbers of 14 suspended particulate matter (SPM) samples collected under baseflow (n = 222) and storm event (n...
متن کاملStructures Linking Physical and Biological Processes in Headwater Streams of the Maybeso Watershed, Southeast Alaska
We focus on headwater streams originating in the mountainous terrain of northern temperate rain forests. These streams rapidly descend from gradients greater than 20% to less than 5% in U-shaped glacial valleys. We use a set of studies on headwater streams in southeast Alaska to define headwater stream catchments, link physical and biological processes, and describe their significance within wa...
متن کاملGeochemical Triggers of Arsenic Mobilization during Managed Aquifer Recharge.
Mobilization of arsenic and other trace metal contaminants during managed aquifer recharge (MAR) poses a challenge to maintaining local groundwater quality and to ensuring the viability of aquifer storage and recovery techniques. Arsenic release from sediments into solution has occurred during purified recycled water recharge of shallow aquifers within Orange County, CA. Accordingly, we examine...
متن کاملFactors limiting sulfolane biodegradation in contaminated subarctic aquifer substrate
Sulfolane, a water-soluble organosulfur compound, is used industrially worldwide and is associated with one of the largest contaminated groundwater plumes in the state of Alaska. Despite being widely used, little is understood about the degradation of sulfolane in the environment, especially in cold regions. We conducted aerobic and anaerobic microcosm studies to assess the biological and abiot...
