This powerpoint presentation begins by providing a brief overview of a project by the New York City (NYC) Department of Environmental Protection (DEP) to reactivate a series of groundwater wells in Brooklyn and Queens. The wells range in depth from 80 to 150 feet, and water quality concerns include: iron; manganese; hardness; and, MTBE and PCE. Objectives were to: determine the most effective volatile organic compound (VOC) process for application at the Station 6 Demonstration Plant; remove PCE and MTBE; establish target treatment levels; develop a screening analysis that qualitatively evaluates feasibility of applicable technologies; and, quantitatively evaluate technologies that pass screening analysis. A comparison of screened technologies is provided, along with a cost comparison. Includes tables, figures.
