  • CASE STUDY - Moncton, NB Oulton Business School

    The majority of the subsurface contamination was found present under one quarter of the building and associated cornerclassrooms. These classrooms were temporarily sealed off from the rest of the building for health and safety reasons. A large window and section of the brick wall was then removed to allow a mini-excavator access to the classroom. The concrete floor was also removed and the ...

  • Stevens Enhances Groundwater Remediation Effectiveness

    The Stevens HydraProbe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The ...

  • Enhanced degradation of trichloroethene by sodium percarbonate activated with Fe(II) in the presence of citric acid

    Trichloroethene (TCE) degradation by Fe(II)-activated sodium percarbonate (SPC) in the presence of citric acid (CA) in aqueous solution was investigated. The results indicated that the presence of CA enhanced TCE degradation significantly by promoting HO• generation. The presence of Cl−, HCO3− and the initial solution pH appeared to be not ...

  • 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, ...

  • Groundwater Remediation System Cleans Up Oil Spill

    A customer in TX was recently in some hot water with the local municipal water department. Due to excessive rains near the coast of Texas, the water levels have been higher than usual. The company fills storage tanks with diesel at its facility. However one day the tanks were overfilled and instead of going into the ground, they diesel dispersed out via the high rain water and into the local ...

  • New MIOX iAO Technology for Groundwater Remediation at 75% Cost Reduction Case Study

    Cl₂/UV AOP treatment processes are highly complex and dependent on a number of water chemistry and treatment process parameters. With over three years of direct experience, MIOX is in a unique position to apply its expertise towards customer-specific optimization of Cl₂/UV AOP treatment processes with the goal of reducing costs and improving safety. The use of MIOX’s On-Site ...

  • Groundwater remediation pump and treat carberry, Manitoba case study

    Executive Summary Two of four underground gasoline tanks were removed from an old service station located in Carberry, Manitoba a number of years after the facility ceased operating. Two tanks were left on site and were used until 1985, when Manitoba Environment was notified that a domestic well in the vicinity of the abandoned site was contaminated with gasoline. The remaining tanks were ...

  • 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 ...

  • Removal of trichloroethylene in groundwater with two oxidants: siderite catalyzed hydrogen peroxide and sodium persulfate

    Trichloroethylene (TCE), a widely used solvent, is often determined in groundwater and is one of biologically refractory organic contaminants. The aim of the study is to use a new chemical oxidation method to degrade TCE source pollution in groundwater. Fenton-like reactions (hydrogen peroxide catalyzed by iron minerals generates hydroxyl radicals) and sodium persulfate activation (sodium ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • Managanese study: Severn Trent

    Severn Trent Water operates a number of boreholes which abstract water from the underlying Sherwood Sandstone aquifer in the West Midlands.  Prior to 2000, manganese concentrations at one of these sources were reported to be <5µg/l but by 2002 were found to be significantly higher than this.  This posed a possible threat to the source.  Further sampling in 2007 suggested ...

  • Groundwater Remediation

    Groundwater remediation or clean-up is required when concentrations of contaminants exceed or are expected to exceed predetermined levels for the type of resource that is impacted (Grossman et.al., 2008). For example, lead levels in drinking water should not exceed the EPA action level of 0.015 mg/L. What caused the high levels of lead? How can the lead be removed from the aquifer? (Grossman ...

  • Recent papers in groundwater remediation

    Computational cost is a critical issue for large-scale water resource optimization under uncertainty, since time-intensive Monte Carlo simulations are often required to evaluate over multiple parameter realizations. This paper presents an efficient approach for replacing most Monte Carlo simulations with efficient surrogate models within a noisy genetic algorithm (GA). The surrogates are trained ...
