  • N. Railroad Ave. Plume Superfund Site - New Mexico

    The NRAP site is a state-lead site in its 7th year of groundwater treatment operations by in-situ enhanced reductive dechlorination. The site’s lead agency, the New Mexico Environment Department (NMED), recently completed a response action report to document ongoing progress in their remediation efforts. NMED utilized EnviroInsite in that effort to assist in the interpretation of sampling ...

  • Laboratory investigation on the removal of radium from groundwater by Ba(Ra)SO 4 co-precipitation

    The USEPA radionuclides regulations have spurred significant research efforts for developing better technology for radium removal from groundwater. The use of barium chloride to remove radium from groundwater is a promising technique. For that, laboratory experiments were carried out to evaluate the effectiveness of different barium chloride doses on the reduction of radium and its impact on ...

  • 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 and application at ...

  • 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 Every day, more than 77 billion gal of water are withdrawn from aquifers for a variety of uses including human consumption.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 ...

  • Use of Carbon Adsorption Processes in Groundwater Treatment

    Untitled Document Summary: One of the leading treatment technologies for reduction of organic contaminants in groundwater has become the adsorption process utilizing granular activated carbon (GAC). This paper presents a methodology for selecting the proper adsorption system design. The use of the isotherm test for evaluation of carbon adsorption is discussed, with new ...

  • Important things to consider when you have to treat dewatering discharge water at your site

    In many cases when you have to dewater an area of a construction or remediation site to do an excavation or other subsurface work, the water is clean and can be easily discharged without treatment. However, in some cases the soil and groundwater are contaminated, and if dewatering is required, it is highly likely that the discharge water will be contaminated and will require some type of ...

  • 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 with air ...

  • 4 Benefits of Electrocoagulation for Groundwater Treatment

    Even though groundwater sources are somewhat safer from pollution and contamination due to their underground location, they are still susceptible. A factory may not be able to discharge wastes directly into a groundwater source like they can a surface water stream or river. However, there are many other ways that waste could potentially contaminate a groundwater source. Because soil is ...

  • Soil & Groundwater treatment of Chlorinated Solvents

    Project: Treated 675 Cubic Yards of Chlorinated Contaminated Soil and Groundwater Client: Operating Dry Cleaners Location: Lexington, Kentucky Scope of work: In-Situ Bioremediation Project cost: $7,575 (Included earthmoving, labor, and all bioremediation materials) Source of contamination: Leaking UST Project duration: 21 months Status: Treatment Completed: Site will be monitored Description: A ...

  • More efficient alkalisation with ground limestone in groundwater treatment

    Most Finnish groundwater must be alkalised before use as municipal drinking water because it is corrosive. The corrosiveness is due to low pH and softness of water. Groundwater also often contains aggressive carbon dioxide (CO2), so there is more free CO2 than is required to keep calcium and hydrogen carbonate in solution. The most popular alkalisation method in the past was addition of sodium ...

  • TerraTherm to Remediate Soils at the Beede Waste Oil Superfund Site - Case Study

    The Beede Site is the former location of a state-licensed and regulated waste oil recycling and disposal facility. The nearly 41-acre Site is located in a residential area of Plaistow, New Hampshire (NH). Operations at the Site began in the 1920s, and continued until the state of NH ordered its closure in 1994. From the 1920s to 1994, thousands of NH residents and businesses were customers of the ...

  • Model R OXIGEST - Petroleum Refinery - Case Study

    A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant. The plant operates with a Food-to-Mass (F/M) typical of extended aeration conditions ...

  • 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 ...
