Keynote presenter previews NGWA Conference on Hydrogeophysics and Deep Groundwater
Andrea Croskrey, PG, of the Texas Water Development Board will give the keynote presentation at the NGWA Conference on Hydrogeophysics and Deep Groundwater, March 20-21 in Denver, Colorado. Focusing on the use of geophysics—from remote sensing to borehole applications—for groundwater studies, the conference also includes a follow-up to the 2014 NGWA Conference on Characterization of Deep Groundwater. Below Croskrey gives a preview of her presentation as well as what she is looking forward to learning...
Characterization and comparison of iron oxyhydroxide precipitates from biotic and abiotic ...
Removal of iron is an important step in groundwater treatment for drinking water production. It is performed to prevent organoleptic issues and clogging in water supply systems. Iron can be eliminated with a purely physico-chemical (abiotic) method or biotically with the help of iron-oxidizing bacteria (FeOB). Each of the purification methods requires different operating conditions and results in formation of iron oxyhydroxide (FeOOH) precipitates. Knowledge about the differences in composition and properties of...
Case study - Ireland Groundwater Monitoring Program
To fulfill the EU Water Framework Directive (WFD) requirements, a groundwater monitoring program was established by the Environmental Protection Agency of Ireland. This program focuses on providing information to assess the environmental status of surface and groundwater bodies. Read about the program and the example installation in the Bog of the Ring.Technology Used: OTT Orpheus Mini, OTT ITC, and OTT KL 010 Contact Gauges. Background The Environmental Protection Agency of Ireland operates 130 wells (5...
Case study - Groundwater monitoring around hydraulic fracturing sites in Colorado
Hydraulic fracturing or ‘Fracking’ has become more prevalent and controversial in the US in recent years. More than 90 percent of new wells in the US are completed using this method. While it is endorsed by some as a game-changer that promises an increase in the nation’s economy due to energy independence, job creation, and lower energy prices; others are calling for a temporary moratorium or a complete ban on fracking due to environmental concerns.The US government has identified and employed...
E-Z Trays an Integral Part of Levelland`s Groundwater Treatment - Case Study
QED E-Z Tray® Air Strippers an Integral Part of Levelland`s Groundwater Treatment System The refinery at the former Motor Fuels Corporation produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils. It closed in 1954 after 15 years of operation, and the refinery equipment was removed by 1958. The property has since been redeveloped, but the groundwater contains a plume of benzene and 1,2-dichloromethane. This plume is now contaminating the groundwater that supplies the city...
