Soil sorption characteristics of imidacloprid in different Croatian regions
In Croatia, imidacloprid is increasingly used in olive growing areas against the olive fruit fly. Experiments were conducted to examine the relationship between soil properties, imidacloprid concentration and soil sorption capacity. The linear and the Freundlich model adequately described the imidacloprid sorption. Better sorption was observed at lower imidacloprid concentrations and in soils ...

Application of 3D-fluorescence/PARAFAC to monitor the performance of managed aquifer recharge facilities
3D-fluorescence spectroscopy was used as a monitoring tool to describe the fate and transport of dissolved organic matter (DOM) during groundwater recharge using recycled water, imported water, and stormwater at a managed aquifer recharge site in California. The study was supplemented by analysis of conservative wastewater-derived trace organic chemicals using liquid chromatography coupled ...

In Situ Bioremediation of Chlorinated Solvents
ABSTRACT: In situ bioremediation is ongoing at a former manufacturing facility in Portland, Oregon. Shallow groundwater at the site was impacted by chlorinated solvents, primarily trichloroethene and degradation products cis-1,2-dichloroethene and vinyl chloride. In situ chemical oxidation treatment was completed in 2003 via the injection of sodium permanganate in source areas. Subsequent ...

Groundwater monitoring around hydraulic fracturing sites in Colorado - Case study
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 ...
