The manual assists the user in making a preliminary evaluation of the likely effectiveness of various remediation technologies in the event of a release of petroleum products into the saturated zone. The manual helps the user develop a conceptual understanding of site conditions before extensive field studies are completed; discusses remediation goals; identifies and helps the user evaluate technologies capable of meeting remediation goals; and discusses follow-up measures. To help the user develop a conceptual understanding of the site (i.e., conduct a preliminary site assessment) the manual shows how to collect basic information about the subsurface environment and the released product. The manual also provides default values for some parameters if field data are not available or have not yet been collected. The user is then assisted in making a preliminary determination of the likely phase partitioning and mobility of petroleum products in the saturated zone. The three 'phases' considered in the manual are: non-aqueous phase liquid (NAPL); dissolved in groundwater; and sorbed to soil particles. Worksheets are provided to aid in evaluation of the alternative technologies. For each worksheet, factors critical to the successful implementation of a given technology are presented.
