  • Biobarriers for groundwater treatment: a review

    Biobarriers (BBs) are a new type of in situ technology for the remediation of contaminated groundwater. In recent years, this remediation technique has been more and more used in place of traditional Pump & Treat systems or other in situ technologies both in the USA and Europe. This work reviews the main experiences of BBs. The literature contains reports about tests ...

  • In Search of Ideal Groundwater Treatment

    As surface water supplies become increasingly polluted and difficult to treat, the use of groundwater continues to increase. Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption. Worldwide, groundwater makes up 95% of available freshwater, and nearly half of the U.S. population receives all or part of its drinking water from ...

  • The Internet of Water Is Saving Lives While Battling Pollution

    The Problem A condition known as Legionnaires' disease has made headlines after it killed a dozen people in Flint, Michigan in 2014 and 2015 and sickened hundreds in  ...

  • Case study - Chlorinated groundwater treatment

    Problem A Fortune 50 company implemented a remedial project to collect and treat polluted groundwater from a site in Central New York, preventing the mitigation of impacted groundwater from flowing into local waterways. An engineering and construction firm was hired to design and build an effective, efficient groundwater treatment system. Collection of the polluted water would be done ...

  • Case study - Chlorinated groundwater treatment

    Overview A Fortune 50 company implemented a remedial project to collect and treat polluted groundwater from a site in Central New York, preventing the mitigation of impacted groundwater from flowing into local waterways. An engineering and construction firm was hired to design and build an effective, efficient groundwater treatment system. Collection of the polluted water would be ...

  • Wastewater and groundwater

    Nearly 25 percent of the population in the United States—in more than 25 million homes—disposes of wastewater through onsite, or unsewered, systems that return treated effluent to the ground. This is an important public health issue because many of those same homes use wells that rely on groundwater for the drinking water supply. With ...

  • Proven alternatives for aboveground treatment of arsenic in groundwater

    This issue paper identifies and summarizes experiences with proven aboveground treatment alternatives for arsenic in groundwater, and provides information on their relative effectiveness and cost. The information contained in this paper can also be found in the report “Arsenic Treatment Technologies for Soil, Waste, and Water”, EPA542-R-02-004 (Ref. 1.12), which provides cost and ...

  • Groundwater intrusion into leaky sewer systems

    Vast volumes of groundwater are drained by urban sewer systems. This unwanted flow component intrudes into sewer systems through leaky joints or connected house drains. However, unlike urban storm drainage, it has a high seasonal variation corresponding to groundwater storage and long slow recessions similar to baseflow in rivers also fed by shallow groundwater exfiltrating into the surface ...

  • Full-scale SVE system operates in tandem with groundwater treatment

    Since 1993, SVE has been implemented using two designs at the TP Industrial, Inc. (TPI) site in Gardena, CA, to treat soil contaminated with chlorinated solvents. The SVE system was modified in 1997 to improve emissions control efficiency by using carbon adsorption units that treat effluent from an air-stripping system for treating site ground water. By the end of 2007, SVE had removed a ...

  • Demonstration of Resin Adsorption Techology for Treatment of VOCs in Groundwater

  • Demonstration of the HiPOx Advanced Oxidation Technology for the Treatment of MTBE-Contaminated Groundwater

    The HiPOx technology is an advanced oxidation process that incorporates high-precision delivery of ozone and hydrogen peroxide to chemically destroy organic contaminants with the promise of minimizing bromate formation. A MTBE-contaminated groundwater from the Ventura County Naval Base in Port Hueneme, CA was used to evaluate this technology. Due to extremely high concentrations of bromide in the ...


  • Characterization and comparison of iron oxyhydroxide precipitates from biotic and abiotic groundwater treatments

    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 ...

  • Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...
