  • Soil Attenuation Model (SAM) Technical Background Document

    Under a risk-based corrective action (RBCA) process, soils and groundwater impacted by a chemical release are to be remediated or controlled to concentration levels such that further migration will not expose human or environmental receptors to unsafe levels of hazardous constituents. For this purpose, site-specific target levels (SSTLs) must be established for the affected soil mass such that ...


  • Oil shale is not a viable fuel source - Study

    While many are celebrating the end of the 'Peak Oil' concerns because of abundent new sources of oil in shale deposits, a true accounting for all economic and environmental costs to exploit this energy source suggests it may not be a viable proposition at all. Scientists' best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional ...

  • Final effluent monitors protect wastewater treatment efficiency

    Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...


  • Ethanol by-product raises biogas output

    In 2007, the City of Fergus Falls, Minnesota undertook a study to evaluate adding thick corn stillage to the anaerobic digesters at its wastewater treatment plant (WWTP). The goal was to determine the potential for codigesting syrup with biosolids to increase biogas production, while avoiding operational and regulatory problems. The Fergus Falls WWTP operates three digesters in series, two ...

  • The “Social cost of carbon” and climate change policy

    Economist Frank Ackerman has called the “social cost of carbon” the most important number you never heard of. What is the social cost of carbon, where do the numbers come from, and why should policymakers take care when using them? The Obama Administration (and the Bush Administration before it) uses the SCC to assess the benefits of regulations that would limit emissions of carbon ...

  • Voluntary carbon market is fast becoming big business

    If anyone had doubts about the importance of the voluntary carbon market they would certainly have been overcome by the announcement last month by Merrill Lynch of a new carbon offset service to assist businesses to reduce emissions through voluntary offsets. In partnership with ICF International, Merrill Lynch’s new Green and Gold initiative is the latest in a series of moves by major financial ...

  • Toxicological and Environmental Safety Data - Case Study

    Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...

  • The New Environmental Insurance Products: When Does it Make Sense to Buy Them?

Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...


  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...
