  • Characterising aquifer treatment for pathogens in managed aquifer recharge

    In this study the value of subsurface treatment of urban stormwater during Aquifer Storage Transfer Recovery (ASTR) is characterised using quantitative microbial risk assessment (QMRA) methodology. The ASTR project utilizes a multi-barrier treatment train to treat urban stormwater but to date the role of the aquifer has not been quantified. In this study it was estimated that the aquifer barrier ...

  • Reclaimed Water Aquifer Storage and Recovery: Potential Changes in Water Quality

    Aquifer storage recovery (ASR) operations recharge and recover water through the same well or wells, creating a “bubble” of stored water that typically mixes minimally with ambient groundwater once the storage zone has been developed. Because ASR recharge water does not flow through a vadose zone and is not drawn through an aquifer to a distant point of withdrawal, changes in water quality that ...

  • Bacteriological assessment of aquifer storage and recovery (ASR) water in southwest coastal Bangladesh

    Safe drinking water is scarce in southwest coastal Bangladesh. Harvested rainwater and rain-fed pond water are the main sources of drinking water for people living in this area. Both government and non-government organizations are promoting aquifer storage and recovery (ASR) schemes to provide safe drinking water for this population. This study assessed the bacteriological quality of both ...

  • Case study - Mazzei degas separator selected for Wichita aquifer storage and recovery project

    GDT Degas Separator Selected As Best Method For Entrained Gas Bubbles Removal Wichita, KS The Problem: In the 1990s, the City of Wichita, Kansas developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the ...

  • Pathogen inactivation during passage of stormwater through a constructed reedbed and aquifer transfer, storage and recovery

    A study was undertaken to determine the potential inactivation rates of selected enteric microorganisms in captured urban stormwater within a constructed reedbed and in tertiary carbonated aquifer during an Aquifer Storage, Transfer and Recovery (ASTR) scheme. The study was undertaken in-situ in the constructed reedbed and aquifer using diffusion chambers. The results showed that all tested ...

  • Surfactant enhanced aquifer remediation (SEAR) using Ivey-sol surfactant technology

    This paper will focus on the application of Ivey-sol non-ionic surfactant technology to improve the in-situ remediation of petroleum hydrocarbon contamination is soil and bedrock aquifers. Normally hydrophobic organic chemicals (HOC) exhibit limited solubility in groundwater as the contaminants tend to partition onto the soil and bedrock matrix. This partitioning can account for as much as ...

  • Numerical modeling of aquifer thermal energy efficiency under regional groundwater flow: a case study at Oslo Airport

    The main purpose of this paper is to present a robust forward model for simulating extraction and storage of thermal energy in an aquifer. The model is a local three-dimensional finite element model with boundary conditions derived from an analytic large-scale model based on the regional water balance. Numerical investigations and thermo-hydraulic evaluation of a typical dipole ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Comparative assessment of managed aquifer recharge versus constructed wetlands in managing chemical and microbial risks during wastewater reuse: a review

    Constructed wetlands (CWs) and managed aquifer recharge (MAR) represent commonly used natural treatment systems for reclamation and reuse of wastewater. However, each of these technologies have some limitations with respect to removal of different contaminants. Combining these two technologies into a hybrid CW-MAR system will lead to synergy in terms of both water quality and costs. This ...

  • Enhanced oil recovery scheme in the sultanate of oman

    The Facility This project is an Enhanced Oil Recovery Field and is located in the South-Central area of the Sultanate of Oman, approximately 660 kilometers from Muscat and 560 kilometers from Salalah. The design requirements for this Development are similar to most self-sufficient oilfields in a remote desert environment. The primary differences are the steam generation and ...

  • Analytical Solutions for Free-Hydrocarbon Recovery using Skimmer and Dual-Pump Wells

    Accidental release of petroleum hydrocarbons to the subsurface may occur through spills around refineries, leaking pipelines, storage tanks or other sources. If the spill is large, the hydrocarbon liquids may eventually reach a water table and spread laterally in a pancake-like lens. Hydrocarbons that exist as a separate phase are termed light non-aqueous phase liquids (LNAPL). The portion of the ...

  • Integrated solar and wind energy powers oil recovery system

    Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...

  • San Diego formation groundwater development and storage potential.

    Groundwater as a resource has been little utilized in San Diego County, California, compared to neighboring counties to the north. The San Diego formation in southwestern San Diego County is one resource that has seen limited utilization historically, but in recent years has been viewed with increasing interest by local agencies for expanded groundwater development. Potential uses include ...

  • Groundwater banking: opportunities and management challenges

    Groundwater banking is the use of aquifers to store water to balance seasonal or longer-term variations in supply and demand. The large storage capacity provided by aquifers can be a valuable tool for conjunctive use of surface water and groundwater as well as other elements of integrated water resources management. Successful groundwater banking requires favorable hydrogeological conditions to ...
