TAILIEUCHUNG - USEPA REGION 9 TECHNICAL GUIDELINES FOR ACCURATELY DETERMINING VOLATILE ORGANIC COMPOUND (VOC) CONCENTRATIONS IN SOIL AND SOLID MATRICES

This study, the first to investigate workplace contamination in areas in Ghana where e-waste recycling and disposal is carried out, focussed on the main centre for this type of work, at the Agbogbloshie scrap market in Ghana’s capital, Accra. One of the numerous similar, though far smaller, operations that take place throughout Ghana was also investigated, at the location of a scrap dealer in Korforidua, a smaller city to the north of Accra. At these workshops, e-waste is recycled in a crude way, primarily involving manual disassembly and open burning to isolate copper from plastics. Much of the work is carried out by children, commonly. | UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION 9 Quality Assurance Office 75 Hawthorne Street San Francisco CA 94105-3901 USEPA REGION 9 TECHNICAL GUIDELINES FOR ACCURATELY DETERMINING VOLATILE ORGANIC COMPOUND VOC CONCENTRATIONS IN SOIL AND SOLID MATRICES R9QA FINAL December 2005 EPA Region 9 Technical Guidelines for Accurately Determining Volatile Organic Compound Concentration in Soil and Solid Matrices FOREWORD The . Environmental Protection Agency EPA is authorized to make decisions affecting public health and the environment. With the knowledge that there is an inviolable trust in the Agency EPA mandated that environmental data collected by and for the Agency be of known quality and as appropriate legally defensible in relation to the decisions to be made based on them. The AgencyWide Quality System EPA Order A1 EPA Quality Manual for Environmental Programs May 2000 and EPA Order A2 Policy and Program Requirements for the Mandatory Agency-Wide Quality System May 2000 supersedes EPA Order 1984 defines this mandate. The AgencyWide Quality System is intended to ensure that decision makers are provided the necessary knowledge and confidence on which to base their decisions. The responsibility for planning developing and implementing the EPA Region 9 s Quality System resides with the Regional Quality Assurance Manager RQAM and the Quality Assurance Office QA Office . These guidelines have been developed by the RQAM QA Office to support the mission of EPA Region 9. These guidelines update and replace the EPA Region 9 Regional Interim Policy for Determination of Volatile Organic Compound VOC Concentrations in Soil and Solid Matrices June 23 1999. If you have any questions please contact the Region 9 QA Office.
