Continuous Monitoring Deepens Understanding of Karst Aquifers
Overview The Karst Research Institute, part of the Scientific Research Centre of the Slovenian Academy of Sciences and Arts, uses a variety of In-Situ equipment to continuously monitor several caves within the country’s vast, complex network of karst aquifers. Challenge Karst aquifers form when rainwater or groundwater seeps into fissures in soluble rock and begins to dissolve the ...

Groundwater Plume, Source and Risk Identification Using Passive Soil Gas
Abstract The results from sixty passive soil gas (PSG) samplers placed at a grain silo and mixed-use industrial facility with a known chlorinated solvent release aided with the rapid investigation time-schedule. The samplers were used to determine potential sources, plume extent and vapor risks in areas beyond the previous discrete soil sampling and permanent groundwater monitoring well network. ...

Spolchemie site remediation and NanoRem field site application
Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the current ...

Hydraulic and Thermal Response of Groundwater–Surface Water Exchange to Flooding in Experimental Aquifer
Summary The effects of flooding on interactions between streams and shallow aquifers are poorly studied due to the unpredictable nature of flooding events. This study examines groundwater-surface water interactions in a constructed experimental meander over several simulated flood events using hydrologic and thermal monitoring. Detailed steady-state hydraulic head measurements were taken of the ...

Regulatory Aspects of Direct Potable Reuse in California
Introduction California's water supplies are derived from a variety of sources, including local and imported surface water, groundwater, desalinated seawater, and recycled water. Water resources are becoming limited due to population increases, droughts, and reductions in imported water allocations. Furthermore, global climate change may exacerbate the problem in the future. Water recycling for ...

Pump/Recharge Rate Affects Saltwater Intrusion
Untitled Document Many areas of the world use groundwater as their main source of fresh water supply. With the worlds population increasing at alarming rates, the fresh water supply is being continually depleted, increasing the importance of groundwater monitoring. One of the major concerns most commonly found in coastal aquifers, is the induced flow of salt water into fresh ...

Report documents effects of 40 years of groundwater withdrawal
The cumulative effects of 40 years of groundwater withdrawals in the Houston-Galveston region are documented in a report from the United States Geological Survey. Decades of extensive withdrawals have caused the land to sink, or subside. The Houston-Galveston region is one of the largest areas of land surface subsidence in the U.S., according to the agency. Water withdrawals started as early as ...

Climate Change and Water Issues
Water supplies are being threatened by climate change, endangering food and energy supplies as well Any discussion of climate change and water issues runs the risk of creating an artificial distinction between many fundamentally intertwined forces, with water as just one facet of a complex set of challenges. Because climate change interacts not just with water security but also with energy and ...

Case Study: Why Horizontal Ozone Sparge
To avoid costly business interruption and site disturbance, Ganesh Kurse with G & RK Consulting Associates, recommended a non-invasive remedial approach by installing horizontal ozone sparge wells with directional drilling techniques. Although horizontal ozone sparging wells were a new remedial technology to G & RK and the State of Alabama’s underground storage tank (UST) ...

Case study: Chevron - Intel gained from Aquatrack avoids a multi-million dollar problem
Introduction Chevron didn’t become one of the world’s largest and most respected energy companies by following others; they got there by blazing their own trail. With their corporate commitment to being a responsible and environmentally friendly company, Chevron stands apart from their competitors by being open to new ideas. Chevron developed a new technique for revitalizing oil ...

Assessing the transport and fate of MTBE
Untitled Document Abstract The ether oxygenates MTBE and TAME have been used in petroleum fuel formulations in the UK since the mid-1980s and have led to contamination of major aquifers with these chemicals, including the Chalk aquifer of southern England. An assessment is made of the controls on the fate of MTBE and BTEX compounds at a contaminated site on the Chalk aquifer, ...

Indestructible Pumps for Clean Water
Sulzer pumps are used in the production of drinking water in many cities around the world. The special qualities that these pumps possess can be seen at the Zurich Municipal Water Utility. There, the operators have to cope with rising land and energy prices and a challenging topography. A small water flea plays a major role in Zurich. It swims around in a container of drinking water with some of ...

Sustainability of Arizona’s few remaining perennial streams.
Mother Nature made water simple. In general, water comprises a continuum in whatever phase or phases it may occur. If you take some here, you have less somewhere else. Arizona law does not readily account for this simple concept; rather it arbitrarily divides water into different classes to be regulated as if the classes were somehow distinct and separable. This creation of different classes of ...

Management of Mining, Quarrying and Ore-Processing Waste in the European Union
At the request of the Environment Directorate-General of the European Commission, BRGM (Bureau de Recherches Géologiques et Minières) has conducted a study on the management of mining, quarrying and ore-processing waste in the European Union. This project was completed mainly through the use of questionnaire sent to sub- contractors in almost each country of the EU. To assess this information ...
