Spreadsheet‐Based Design Tool for In Situ Anaerobic Bioremediation Using Soluble Substrate

Abstract

A Microsoft Excel spreadsheet-based design tool has been developed to assist remediation professionals in the design for various designs. CE SS is estimated from a nonlinear regression equation that includes terms for the SS injection concentration (C I ), minimum substrate concentration (C MI N ), groundwater travel time between rows of injection wells (T T ), SS half-life (T H ), substrate reinjection time interval (T R ), and pore volumes of substrate solution injected (PV). With this tool, users can quickly compare the relative costs and performance of different injection alternatives and identify the best designfor their specific site conditions. The design process embodied in the tool includes: (1)
