  • 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 ...

  • Assessments of Effect of Land-use change in Groundwater Storage

    Assessment of effects due to land use change in groundwater storage is performed in Kathmandu Valley basin of 651 km2. Effect of land use change is found to be more in groundwater than surface water. Increased impervious area due to land use change has been major factor in contributing to decreased infiltration. The ground water storage is depleting due to fact that the extraction of groundwater ...


  • Aquifer storage recovery efficiency for saline groundwater regions as influenced by buffer storage volume and storage time

    Abstract:                             Field experiments were carried out in a cavity type of Aquifer Storage Recovery well installed in an aquifer having highly saline native groundwater (EC = 28.4 dS m-1). Good quality canal water (EC = 0.46 dS m-1) ...

  • Groundwater Monitoring Case Study

    Global has been contracted by the Michigan Department of Environmental Quality, Remediation and Redevelopment Division (MDEQ RRD) to conduct quarterly sampling at a former gas station and adjacent property located near a State of Michigan owned public assess site to Torch Lake. The purpose of the sampling is to assure that there are no impacts to the surface water located downgradient of the ...

  • BTEX remediation in groundwater

    BTEX contamination in groundwater from a leaking underground storage tank was cost-effectively treated with two applications of Petrox. This project demonstrates the rapid degradation of petroleum components when high populations of Petrox aerobic microbes are injected. The pre-treatment concentrations of Toluene and Xylene were 1,198ppb and 2,408 ppb, respectively. Ten units of Petrox aerobic ...

  • In Search of Ideal Groundwater Treatment

    As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • Depleting groundwater – an opportunity for flood storage? A case study from part of the Ganges River basin, India

    Storing excess rainwater underground can become key in mitigating the frequency and magnitude of flood events. In this context, assessment of depleted groundwater storage that can be refilled in water surplus periods is imperative. The study uses Gravity Recovery and Climate Experiment (GRACE) data to identify variations in groundwater storage in the monsoonal Ramganga River basin (tributary ...

  • Effects of aquifer thermal energy storage on groundwater quality and the consequences for drinking water production: a case study from the Netherlands

    We used data from an aquifer thermal energy storage (ATES) system located 570 m from a public water supply well field in the south of the Netherlands to investigate the relation between production of renewable energy with an ATES system and the production of drinking water. The data show that the groundwater circulation by the ATES system can impact chemical groundwater quality by introducing ...

  • Groundwater intrusion into leaky sewer systems

    Vast volumes of groundwater are drained by urban sewer systems. This unwanted flow component intrudes into sewer systems through leaky joints or connected house drains. However, unlike urban storm drainage, it has a high seasonal variation corresponding to groundwater storage and long slow recessions similar to baseflow in rivers also fed by shallow groundwater exfiltrating into the surface ...

  • 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 ...

  • Karst groundwater: a challenge for new resources

    Karst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow, large voids, high flow velocities up to several hundreds of m/h, high flow rate springs up to some tens of m3/s. Different conceptual models, known from the literature, attempt to take into account all these particularities. The ...

  • Large Precipitation Events are Critical in Replenishing Groundwater Resources

    Large precipitation events that occur about every 10 years are a critical source of recharge for replenishing groundwater resources, according to a new study by the U.S. Geological Survey and the Bureau of Reclamation. Groundwater is a vital source of water in the western United States, and will be increasingly ...
