REMChlor-MD (Version 1.0)

REMChlor-MD, developed for the Department of Defense ESTCP program, is an easy-to-use, free software tool that can assist site personnel better understand matrix diffusion and help site stakeholders determine if matrix diffusion processes are significant enough to cause “rebounding” of downgradient plume concentrations above remediation goals after plume remediation or isolation is complete. Having this information readily available before a remedy is implemented, could assist site stakeholders select more appropriate remedies and improve effective risk communication with regulators and the public.

Features

REMChlor-MD was developed as a cost-effective management tool for addressing contamination in a broad range of geological settings. The tool allows for efficient modeling of matrix diffusion in aquitards, layered and heterogeneous systems, and rock systems with parallel fractures.The Toolkit allows the accounting of several types of source and plume remediation activities. As a screening tool, REMChlor-MD attempts to assist site managers and site consultants better understand matrix diffusion and help site stakeholders determine if matrix diffusion processes are significant enough to cause “rebounding” of downgradient plume concentrations above remediation goals after plume remediation or isolation is complete. Having this information readily available before a remedy is implemented, could assist site stakeholders select more appropriate remedies and improve effective risk communication with regulators and the public. Furthermore, addressing extended remediation time frames caused by matrix diffusion would lead to savings in project costs.

Technical Support

Limited technical support is available from Shahla K.Farhat.

System Requirements

REMChlor-MD requires a computer capable of running Microsoft® Excel (2016 version 16.0.9226.2114 or newer) for Windows 7 and Windows 10. 

Operation requires an IBM-compatible PC equipped with a Pentium or later processor running at a minimum of 450 MHz. A minimum of 256 MB of system memory (RAM) is strongly recommended. Computers not meeting these recommendations will experience slow running times and/or problems with memory.  REMChlor-MD versions are available for both the 32-bit and 64-bit versions of Excel (the default Excel installation is 32-bit).
