Enhancement of the HWRIC (Hazardous Waste Research and Information Center) Database. Year 2 with an Evaluation of Database Content

摘要

The Hazardous Waste Research and Information Center (HWRIC) database has been in the development and enhancement stages for three years. The method for collection and addition of historic data has evolved over the years as the available information has become more familiar and better understood by database users. Evaluation of the relative contribution to the HWRIC database of the available large-volume computerized datasets and the hand-gathered historic data has been an ongoing process. The information gathered in the evaluation has not been presented previously in a document. The analyses have yielded valuable information on the quality and quantity of data now available in the HWRIC database system.
