  • Mariposa compost facility odor remediation update

    Staring in the winter of 2006 the staff at the Mariposa Compost Facility worked quickly to make process changes to bring odor issues under control. Here is the latest chapter in their story. Odor (incident) Logs In January 2007 the Local Environmental Agency (LEA) provided "odor logs" to the county residents that were troubled by the compost facility's odors. The odor logs were ...

  • Accelerated remediation of chlorinated solvents using a horizontal ZVI PRB in combination with ISCR for enhanced Anaerobic remediation

    Description: Industrial Site in Apeldoorn, Netherlands Consultant and Contractor: NTP Enschede Approach: Severe soil and shallow groundwater contamination by metals and chlorinated solvents (cVOCs) was detected at the site. A comprehensive site remediation plan was developed by NTP and Adventus Group to provide accelerated site clean-up, that included: • Installation of two ...


  • Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

    A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...

  • Odor issues at Mariposa MSW composting facility

    The Mariposa County MSW composting facility was built at the county landfill to remove some dry recyclables from the waste stream and to produce compost for daily cover. One key motivation was to increase the lifespan of the landfill and to postpone a costly long-haul. The facility was permitted, designed and built by a team of engineers and vendors. It began operation in the summer of 2006. ECS ...

  • Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

    Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

  • Aire-O2 Triton Solves Bulking Problem

    The Dubai Investments Park (DIP) wastewater treatment plant (WWTP) is located about 20 miles south of the Burj Khalifa – the world’s tallest building. The oxidation ditch activated sludge plant recently found itself strained by filamentous sludge bulking likely caused by high organic loads, high summer temperatures and inevitable low dissolved ...

  • Triton solves bulk of the problem case study

    The Dubai Investments Park (DIP) wastewater treatment plant (WWTP) is located about 20 miles south of the Burj Khalifa – the world’s tallest building. The oxidation ditch activated sludge plant recently found itself strained by filamentous sludge bulking likely caused by high organic loads, high summer temperatures and inevitable low dissolved oxygen. The problem was easily ...

  • Combined use of ISCO and ISCR to treat CVOCs at industrial site in Texas, USA

    Groundwater at an industrial site in Texas is impacted with Chlorinated Volatile Organic Carbon’s (CVOCs), primarily PCE and TCE, from historical waste disposal. The topography at the site slopes steeply towards a small channel where the groundwater discharges. Depth to groundwater ranges from approximately 20 ft bgs at the source area to 1 ft bgs close to the channel. The soil consists of silty ...


  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • 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 ...

  • Solidification/Stabilization

    Introduction: As for in situ solidification/stabilization (S/S), ex situ S/S contaminants are physically bound or enclosed within a stabilized mass (solidification), or chemical reactions are induced between the stabilizing agent and contaminants to reduce their mobility (stabilization). Ex situ S/S, however, typically requires disposal of the resultant materials. Under CERCLA material can be ...

  • SolarBee Technical Bulletin

    A. SOLARBEE OVERVIEW 1. Origin of the SolarBee. Pump Systems, Inc. (PSI) developed, built and installed its first solar powered mixer in Dickinson, ND, in the summer of 1998. It was installed into a 30 acre x 13 foot deep municipal wastewater reservoir which had a long history of toxicity associated with ammonia, odor, and stratification problems. In six weeks the entire reservoir cleared up to ...
