  • DOD evaluates bioaugmentation for remediating low-pH aquifers

    The US Department of Defense (DOD) has completed pilot-scale work on the 'MAG-1' site at Fort Dix, NJ, to test suitability of anaerobic bioremediation for an aquifer with low pH. Project results will be used to design full-scale ground-water treatment at MAG-1. In addition, technical criteria gained from the demonstration will be integrated into DOD’s remediation strategy for its many facilities ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Geotube Dewatering Technology Used To Alleviate Acid Runoff Problem from Mine Tailings - Case Study

    Construction on 1-99 in Pennsylvania unearths pyretic rock; Geotube units used to contain minerals that could contaminate groundwater. Many states are faced with the problem of dealing with tailings and residues from mining, road building, and other sources that pose a threat to groundwater. Residues can come from both old inventories of stockpiled material, as well as those materials ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...
