New Documents and Web Resources

Considerations Regarding Application of Permanganate for Remedies in Tennessee. This white paper was put together by Tennessee members of the State Coalition For the Remediation of Drycleaners. The paper presents their program's experience using in-situ chemical oxidation as a remediation technology in the Tennessee Drycleaner remediation program (June 2006, 11 pages). View or download at http://www.drycleancoalition.org/download/tn_MnO4_injections_2006.pdf .

The Remediation Technologies Development Forum: Major Accomplishments: 1992-2006 (EPA 542-F-06-005). The U.S. Environmental Protection Agency (EPA) established the Remediation Technologies Development Forum (RTDF) in 1992 to enhance the development and application of innovative hazardous waste characterization and treatment technologies. One of the RTDF's defining features is that it fosters collaboration between the public and private sectors. Eight self-managed RTDF Action Teams formed over the years. Each brought together representatives from government, industry, and academia to further develop and promote a specific technology or address a specific environmental problem area. Action Team members provided the knowledge and the resources (both in terms of monetary contributions and in-kind services) needed to conduct laboratory and field demonstrations and develop reports, guidance documents, and training products related to their teams' topic of interest. This factsheet highlights the RTDF Action Teams' major accomplishments (August 2006, 4 pages). View or download at http://clu-in.org/download/rtdf/542f06005.pdf .

Evaluating, Optimizing, or Ending Post-Closure Care at MSW Landfills Based on Site-Specific Data Evaluation (ALT-4). This document was produced by the Interstate Technical and Regulatory Council (ITRC). Post-closure care (PCC) at a municipal solid waste (MSW) landfill ensures that a solid waste facility is managed after final closure so that it does not pose a threat to human health and the environment (HH&E). Traditionally, 30 years has been considered the minimum period that PCC must be performed. However, there is no national-and to some extent no consistent state-based structured process for evaluating, optimizing, or potentially ending PCC. This guidance illustrates a methodology to systematically evaluate the condition of the closed landfill, the waste it contains, the setting and the relevant decisions to manage, reduce, or potentially end PCC activities according to the reduced threat to HH&E (September 2006, 164 Pages).

Fractured Bedrock Focus Area updated! Published reports and conference presentations of characterization and remediation of contaminated ground water in fractured bedrock sites are collected and summarized in the website. The site contains 90 case studies, which are evenly split between pilot studies and full scale application. Almost half of the sites have, or are suspected of having NAPL. Over a third of site managers have chosen bioremediation and one quarter have chosen pump and treat and another quarter have chosen oxidation for a remediation technology. Only one technical Impracticability waiver has been requested and five No Further Action certificates were issued by the state regulatory agencies. Seventy-five percent of the sites are located in New York, New Jersey, Massachusetts, and Pennsylvania. For more information, see http://clu-in.org/fracrock .

NATO/CCMS Pilot Study: Prevention and Remediation Issues in Selected Industrial Sectors Athens, Greece June 4-7, 2006.

The presentations from the meeting are now available for viewing at http://clu-in.org/athens . The agenda and other background material on the Pilot Study are available at http://www.nato.int/ccms .

Technology News and Trends - current issue (EPA 542-N-06-005). This issue of TNT highlights the use of soil amendments in remediation, revitalization, and reuse of disturbed land in diverse industrial, rural, and urban settings. Using various waste products to reclaim previously unusable or devalued land, these soil- amendment applications illustrate that industrial residuals can provide a cost-effective means for in-situ remediation. Such success stories reflect the Agency's growing efforts to identify innovative technology solutions for remediation and revitalization, to remove obstacles impeding redevelopment, and to develop measures for evaluating the various stages of ecological damage and repair (October 2006, 6 pages).

EUGRIS Corner. New Documents on EUGRIS, the platform for European contaminated soil and water information. See the following link to access the following three documents: http://www.eugris.info/Whatsnew.asp.

  • International Centre for Soil and Contaminated Sites 2006, Manual for Biological Remediation Techniques - The manual of the German Federal Environment Agency gives a review of the spectrum of different biological remediation techniques. Individual procedures are described in a compact form and fields of application with their respective advantages and drawbacks are outlined.
  • Department for Environment, Food and Rural Affairs - DEFRA 2006, River Basin Planning Guidance Released. Defra and the Welsh Assembly Government are issuing this guidance to the Environment Agency on river basin planning, setting out their expectations in relation to the principles and key steps of the river basin planning process and the content of the documents which the Agency must produce.
  • Department for Environment, Food and Rural Affairs - Defra, Water Framework Directive Web Page. The Water Framework Directive (WFD) is the most substantial piece of EC water legislation to date. It requires all inland and coastal waters to reach 'good status' by 2015. It will do this by establishing a river basin district structure within which demanding environmental objectives will be set, including ecological targets for surface waters.
  • NITRABAR Project Introductory Factsheet. Remediation of Agricultural Diffuse NITRAte Polluted Waters through the Implementation of a Permeable Reactive Barrier. Essentially, the system is a narrow trench, installed between the field and a water body, which is filled with a mixture of natural materials. As groundwater, runoff and field drainage waters pass through the system the nitrates are converted to nitrogen gas by mirco- organisms which attach themselves to, or live in between, the materials. It is expected that this approach will achieve an 85% reduction in the nitrate level in waters passing through the system. The project aims to demonstrate the application of the NITRABAR system in the agricultural setting and enable others to replicate the system throughout Europe. The system will be installed at the eco- millennium environmental centre, Ballymena, Northern Ireland.

Conferences and Symposia

Reminder! Alternative Landfill Cover Workshops. These 2.5-day workshops will be held in Chicago, IL (Oct. 16-18), Denver, CO (Nov. 28-30) and Riverside, CA (Jan. 23-25, 2007). Often called evapotranspiration (ET) covers, these innovative designs are of considerable interest to the solid waste industry due to performance, cost, and long-term stability. The workshops are intended to teach consultants and engineers how to design and submit quality proposals for ET covers, and to teach regulators how to evaluate those proposals. Participants will get an understanding of the hydraulic properties of these covers, how to optimize designs with models, and how to ensure that the final product is environmentally protective. The most current research on field performance, monitoring, economics and construction techniques will be presented. For more information and to register, see http://www.landfillcover.dri.edu/ .
