The Lognormal Distribution in Environmental Applications

The Technology Support Projects, Technology Support Center (TSC) for Monitoring and Site Characterization was established in 1987 as a result of an agreement between the Office of Research and Development (ORD), the Office of Solid Waste and Emergency Response (OSWER) and all ten Regional Offices. The objectives of the Technology Support Project and the TSC were to make available and provide ORD's state-of-the-science contaminant characterization technologies and expertise to Regional staff, facilitate the evaluation and application of site characterization technologies at Superfund and RCRA sites, and to improve communications between Regions and ORD Laboratories. The TSC identified a need to provide federal, state, and private environmental scientists working on hazardous waste sites with a technical issue paper that identifies data assessment applications that can be implemented to better define and identify the distribution of hazardous waste site contaminants. The examples given in this Issue paper and the recommendations provided were the result of numerous data assessment approaches performed by the TSC at hazardous waste sites. Mr. John Nocerino provided guidance and suggestions that greatly enhanced the quality of this Issue Paper. This paper was prepared by A. K. Singh, A. Singh, and M. Engelhardt. Support for this project was provided by the EPA National Exposure Research Laboratory's Environmental Sciences Division with the assistance of the Superfund Technical Support Projects Technology Support Center for Monitoring and Site Characterization, OSWER’s Technology Innovation Office, the U.S. DOE Idaho National Engineering and Environmental Laboratory, and the Associated Western Universities Faculty Fellowship Program.
