Introduction

The Remediation ToolKit provides an integrated data management, visualization, trend analysis, and modeling platform for evaluating the effectiveness of Monitored Natural Attenuation. The Remediation ToolKit combines three different software applications (BioTrends, SEQUENCE and BioTracker) into one integrated solution for evaluating, visualizing and modeling natural attenuation processes. Each package contains a seamless interface with a comprehensive Project Data Management System (Project DMS), and a chemical properties database (CHEMbase).

The Project DMS is a comprehensive data management system that provides a graphical interface to work with monitoring station data, project chemicals, MCL values, and chemical monitoring data. Templates are provided to facilitate manual data entry, and a powerful import utility makes it easy to import data from most spreadsheets or existing data management systems.

BioTrends contains of a suite of data analysis and plotting tools for evaluating spatial and temporal trends with x-y charts, calculating first-order degradation rates using the conservative tracer method or the method of Buscheck and Alcantar, calculating sequential transformation rates, calculating site natural attenuation "scores" using EPA screening criteria, and modeling groundwater transport with the BIOSCREEN model.

SEQUENCE is an innovative data visualization package for simultaneously evaluating spatial and temporal trends in the groundwater chemistry. SEQUENCE uses a modified radial diagram mapping technique to plot groundwater sampling data for multiple chemical species, and multiple sampling events. These radial diagram maps are the perfect tool for identifying and evaluating the trends needed to support natural attenuation as a remedial strategy for a contaminated site.

BioTracker is an new screening tool for modeling natural attenuation including optional sequential transformation reactions and chloride release during reductive dehalogenation reactions. BioTracker uses a unique visualization technique for plotting flowpath trajectories down-gradient from source areas based on a contour map of observed groundwater elevations.
