Assessing selenium contamination in the irrigated stream–aquifer system of the Arkansas river, Colorado
Received for publication December 4, 2008. Prudent interventions for reducing selenium (Se) in groundwater and streams within an irrigated river valley must be guided by a sound understanding of current field conditions. An emerging picture of the nature of Se contamination within the Lower Arkansas River Valley in Colorado is provided by data from a large number of groundwater and surface water ...

Tidal influences on unconfined water levels in wells.
Tidal effects have the potential to measurably affect water level measurements and the estimation of groundwater flow direction and gradient. This has significant implications for the prediction and monitoring of contaminant plumes in coastal areas. Studies were conducted at two near-coastal sites in San Diego County, California, to evaluate the impact of tidal variability on the interpretation ...

Optimal location of artificial recharge of treated wastewater using fuzzy logic approach
Increasing water demands in light of limited water resources have intensified exploitation and drawdown of groundwater. On the other hand, rising water demand has accelerated wastewater production. Therefore, urban wastewater management via artificial recharge may play a significant role in aquifer management. While site selection for artificial recharge projects is a major challenge, fuzzy ...

Groundwater Flow in Arsenic-Contaminated Aquifer, Mekong Delta, Cambodia
ABSTRACT To advance understanding of hydrologies I influences on As concentrations within groundwaters of Southeast Asia, the flow system of an As-rich aquifer on the Mekong Delta in Cambodia where flow patterns have not been disturbed by irrigation well pumping was examined. Monitoring of water levels in a network of installed wells, extending over a 50knr area, indicates that groundwater flow ...

Aerobics to the Rescue - Using Compatible Technologies to Improve Groundwater Remediation
Background Increased opportunities for contaminated property redevelopment have propelled property owners to evaluate options for accelerating site remediation. In some cases a containment technology may have been implemented to mitigate the off-property migration of contamination as the most practical option at the time. Focusing on the property's redevelopment potential, there is new ...
