  • On-Site Incineration Tames Arsenal Waste Mixture

    Toxic wastes from various chemical processing activities at Rocky Mountain Arsenal (RMA) had accumulated in on-site evaporation basins over many years. The highly corrosive wastes, which posed environmental and potential health hazards, were by-products of the U.S. government’s chemical weapons program during World War 11 and its later weapons disposal program, as weIl as sorne pesticide ...


  • Specifying allowable leakage rates

    Introduction Allowable Leakage Rates or Action Leakage Rates (ALRs) are specified for installed geomembranes to quantify the maximum allowable liquid leakage. If the ALR is exceeded, corrective action must be taken to reduce the leakage rate below the set limit. To lower the leakage, the holes in the geomembrane are located and repaired. In some cases, the ALR is set so low that, ...

  • Wetland Project in Oman Achieves Impressive Milestone

    In third quarter of 2012, the Phase 2 expansion of the Nimr Water Treatment Plant (NWTP) was implemented 1.5 month ahead of the construction deadline and without any lost time injuries. With the completed expansion, the NWTP treatment capacity has increased from 45,000 m3/day to 95,000 m3/day.

  • Analysis of monitoring results of the separation and greywater treatment system at Chester Woods Park, Olmsted County, Minn.

    Introduction In 1993, Olmsted County installed an advanced individual sewage treatment system (ISTS) at the caretaker's residence at a County-owned park to demonstrate waste load reduction and downsizing of drainfield area. The subject system has two components--1) a composting/vermiculture blackwater system and a 2) aerobic graywater treatment system. The separation of the high strength ...
