IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH
The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing ...

Hydrogeochemical and isotopic characterization of groundwater at Žitný Island (SW Slovakia)
Hydrogeochemical investigations and spatial variations studies on the distribution of water isotopes and radiocarbon in the groundwater of Žitný Island (Rye Island) were carried out. Žitný Island represents the largest groundwater reservoir in Central Europe (about 10 Gm3). The chemical composition of the groundwater of Žitný Island depends mainly on the chemical composition of Danube water, ...

Using solver to determine vertical groundwater velocities by temperature variations, Purdue University, Indiana, USA
Vertical groundwater velocities can be estimated based on directions of groundwater thermal gradients. Temperature-depth profiles were obtained from 12 monitoring wells at 3 different times of the year (Fall, Winter, and Spring) in West Lafayette, Indiana (USA) mainly on the Purdue University campus. Microsoft Excel Solver was used to match plots of groundwater temperature distribution in the ...

Removing VOCs from Municipal Water Supply - Case Study
QED E-Z Tray® Air Strippers Removing Volatile Compounds in Cheyenne’s Drinking Water The U.S. Army Corps of Engineers (USACE) – Omaha District has funded the design and construction of a new groundwater treatment plant in Cheyenne, Wyoming to treat groundwater from the city’s Borie well field. This important groundwater supply was apparently contaminated with ...

High resolution accurate mass spectrometry as a technique for characterization of complex lysimeter leachate samples
Lysimeter studies can be used to identify and quantify soil degradates of agrochemicals (“metabolites”) which have the potential to leach to groundwater. However, the apparent metabolic profile of such lysimeter leachate samples will often be significantly more complex than would be expected in true groundwater samples. This is particularly true for S‐metolachlor, which has an extremely ...

Cyto- and genotoxic profile of groundwater used as drinking water supply before and after disinfection
The assessment of the toxicological properties of raw groundwater may be useful to predict the type and quality of tap water. Contaminants in groundwater are known to be able to affect the disinfection process, resulting in the formation of substances that are cytotoxic and/or genotoxic. Though the European directive (98/83/EC, which establishes maximum levels for contaminants in raw water ...

Persistence and sorption of imazapyr in three Argentinean soils
Imazapyr is a herbicide widely used for weed control in imidazolinone‐tolerant sunflower. Imazapyr has a high potential for leaching into groundwater because it is highly water‐soluble, persistent in soil, and only weakly sorbed by soils. There is a lack of information available in Argentina concerning groundwater leaching of imazapyr. Therefore, the objective of the present study was to ...

World War II Memorial, DC - Case Study
In 2003, AdEdge Water Technologies began working closely with EarthTech, the assigned engineering firm responsible for specifying and selecting the various water treatment systems serving the new National World War II Monument in Washington, DC. Stormwater and groundwater control and treatment are essential aspects of this project given the location of the site on the Mall adjacent to the ...

High-Resolution Site Characterization with Multilevel Systems
Within the last few years, the U.S. EPA added a new focus area on high-resolution site characterization (HRSC) to their Contaminated Site Clean-Up Information (CLU-IN) website. The U.S. EPA’s definition of HRSC is: “High-resolution site characterization (HRSC) strategies and techniques use scale-appropriate measurement and sample density to define contaminant distributions, and the ...

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, ...
