  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • Engineered wetland removes subsurface hydrocarbons while providing beneficial reuse

    British Petroleum (BP) is operating an engineered wetland to treat petroleum-contaminated groundwater at a 300-acre site in Casper, WY. Release of petroleum products during refinery operations from 1908 until 1991 resulted in significant petroleum hydrocarbon contamination. Over 44,000 yd3 of LNAPL were removed by dual-phase recovery wells and oil/water separators constructed in 1981, but ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Standardizing grinder line helps Richmond firm reduce costs

    Wood waste processors, like most professionals, are experts at adapting to changing times, conditions or economics. That change will, of course, vary according to the situation at hand: if the issue is transportation-related, they will work to shorten routes or find more fuel-efficient vehicles; if the issue is cost, they will find a way to do things more efficiently; and so on. For Grind-All ...
