  • Deep groundwater collection tenches by the bio-polymer drain method

    Introduction The installation of deep drainage trenches has long been a risk-filled and costly endeavor, conventional installation techniques involve dewatering, sheeting and shoring, and danger to personnel working in the trench from trench collapse. Recently, due to the public's concern for the environment and the need to preserve groundwater resources, there has been an increased demand ...

  • Case study - Gas plant groundwater remediation

    One-pass trenching method used for a gas plant groundwater remediation project Not many environmental engineers have heard of one-pass trenching and even fewer have actually applied this cutting-edge technology to environmental control and clean-up. However, a growing number of companies are starting to use this technology, resulting in decreased cost of installation and increased system ...

  • Leachate Collection & Removal Systems – Pump Stations

    Romtec Utilities designs and supplies pump stations for many different types of applications, including leachate collection and removal systems. Leachate pump stations are required whenever water passes through a bed of solids and extracts contaminating elements. The most common scenario for collecting and pumping leachate is for landfills, but there are industrial ...

  • Nitrogen and carbon dynamics beneath on-site wastewater treatment systems in Pitt County, North Carolina

    On-site wastewater treatment systems (OWS) are a potentially significant non-point source of nutrients to groundwater and surface waters, and are extensively used in coastal North Carolina. The goal of this study was to determine the treatment efficiency of four OWS in reducing total dissolved nitrogen (TDN) and dissolved organic carbon (DOC) concentrations before discharge to groundwater and/or ...

  • Case study – BTEX contamination - Kentucky

    In 1992, remedial activities began at the Shively Service Center located in Radcliff, Kentucky. After the leaking underground storage tanks were removed from the site approximately 1,500 cubic yards of BTEX impacted soil was excavated and disposed off-site from the tank pits. Based on the review of historical sampling activities it was believed that the majority of the impacted soils were removed ...

  • Sustainable, Low-maintenance Disinfection for Onsite Systems

    Most of the regulations applicable for onsite wastewater treatment system are based on the use of native soil for effluent dispersal. However, there are more and more situations where dispersal of effluent in native soil is impossible: repairs of existing systems on undersized lots for implementation of required dispersal fields: sites located in soils having low permeability: or where the ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...


  • Stormwater Best Management Practices (BMP)

    Storm water is the result of rain or snow melt that collects in an area that can drain from into a nearby body of waters such as a lake or river. The water can collect on roof tops, parking lots, saturated ground, roads, etc. The problem is that many of the pollutants of our modern living such as oil, grease, pesticides, sediment, salt, and animal waste are washed away within the storm water and ...

  • Conducting The Phase I Assessment - Records Review

     This is the second in a series of five articles relating to conducting Phase I Environmental Site assessments. Each article attempts to give the reader a thorough understanding of a specific aspect of the Phase I process and Clayton’s commitment to meeting or exceeding the requirements of ASTM Standard E 1527 Standard Practice for Environmental Site Assessments: Phase I Environmental Site ...


  • Compost in the mix for storm water management

    Bioretention areas, also known as rain gardens, are increasingly being used to capture and treat storm water runoff from impervious surfaces such as roofs, sidewalks and parking lots. These landscaped areas often feature native plants installed in an engineered soil mixture that includes compost. “Bioretention areas or rain gardens are an attractive storm water Best Management Practice (BMP) ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • Stormwater Management for Urban Environments

    IntroductionElmhurst College, a hundred-thirty-five year old private learning institution, is proceeding with a campus redevelopment project that will include a one hundred seventy bed residence hall. In addition, the college continues to be a role model for sustainable site design and an educational resource for both students and the community.The need for additional housing, due to ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...
