This study compared pump and treat, bioremediation, and bioremediation/pump and treat for cleanup of a chemical plume using BIOPLUME 2, a numerical solute transport code which simulates the transport of dissolved hydrocarbons under oxygen-limited biodegradation. Nineteen remediation scenarios were evaluated under one set of hydrogeologic and chemical conditions using different injection and extraction well configurations and injected dissolved oxygen (D.O.) concentrations of 8 or 50 parts per million (ppm). The cleanup objective was to reduce the concentration of naphthalene in the plume by the greatest percentage without increasing the volume of contaminated ground water in the aquifer. Each scenario was ranked in terms of plume control and contaminant concentration reduction for a one-year remediation period. Based on the performance criteria, scenarios that included pump and treat were superior in containing the migration of the plume and in restricting the plume from separating into smaller, localized plumes or hot spots''.
