All DSTs that were evaluated are free to the public.
BioPIC Tool for the Selection of Bioremediation Approaches at Chlorinated Solvent Sites
The Department of Defense's (DoD) Environmental Security Technology Certification Program (ESTCP) has developed an easy-to-use tool called BioPIC to facilitate bioremediation decision-making based on site-specific physical and biogeochemical characteristics. This research project determined the relationship between biogeochemical parameters and degradation rates for known degradation pathways of chlorinated ethenes (primarily PCE, TCE, and daughter products). Data from 90+ sites was used to establish correlations between the naturally attained rate constant and the abundance of specific parameters. Associations were then established for parameters such as Dehalococcoides (Dhc) densities, reductase densities, dissolved oxygen, oxidation-reduction potential, magnetic susceptibility, Fe(II), Mn(II), methane, ethane, total organic carbon, and others. These associations were used to develop a quantitative framework and decision logic for the screening tool. Based on site-specific conditions, the tool will provide screening considerations to determine if monitored natural attenuation (MNA), biostimulation, biologically mediated abiotic reductive dechlorination, or bioaugmentation is the most appropriate remedial approach.
SiteWise™ Tool for Green and Sustainable Remediation
SiteWise is an Excel-based remedy selection and optimization tool for green and sustainable remediation (GSR) planners.

The companion user guide includes instructions for using SiteWise and the basis of calculations.
EPA Dataset/Databases for Ecological Risk Assessment of Contaminated Sites
To assess the potential for risk from contaminated sediments and to help determine contamination levels for remedial designs, EPA's Land Research Program has developed several ecological risk assessment tools including: 1) Biota-Sediment Accumulation Factor Data Set, which can be used to evaluate the transfer of chemicals from sediments into the aquatic food chain; 2) PCB Residue Effects (PCBRes) Database, an abundance of information for risk assessors to use for correlating polychlorinated biphenyls (PCBs) and other dioxin-like compound residues with toxic effects and developing Toxicity Reference Values (TRVs); and 3) ECOTOX Database, for use when risk assessors and managers need to develop TRVs for sediment sites that have contaminants other than, or in addition to, PCBs and dioxins and provides ready access to single-chemical toxicity information for aquatic and terrestrial life. Each of these tools facilitate a scientifically defensible risk assessment, improve the decision-making ability of risk managers at Superfund and other contaminated sites, and facilitate successful remediation efforts.
FootPrint is a simple and user-friendly screening model used to estimate the length and surface area of benzene, toluene, ethylbenzene, and xylene (BTEX) plumes in ground water, produced from a spill of gasoline that contains ethanol. Ethanol has a potential negative impact on the natural biodegradation of BTEX compounds in ground water. The primary objective of the software is to predict the increase in surface area of the plume of BTEX compounds or any other chemical of concern (COC) due to the presence of ethanol in ground water. FootPrint estimates the area of a plume of particular BTEX compounds that are contained within two biodegradation zones: 1) a zone that is immediately adjacent to the source, where ethanol is present in high concentration and no biodegradation of the BTEX compounds (or other COC) is allowed, and 2) a second zone, where the ethanol concentration is negligible due to the natural biodegradation of ethanol in the first zone and biodegradation of the BTEX compound (or other COC) contributes to attenuation in concentration of the BTEX compounds. FootPrint is based on the modified version of the Domenico model (1987) published by Martin-Hayden and Robbins (1997). This model is an approximate analytical solution of the advective-dispersive solute transport equation with first-order decay. The model of Martin-Hayden and Robbins (1997) was further modified in FootPrint to allow zero-order decay as well (see Appendix B of the user's manual for details). As a result, FootPrint can independently describe the natural biodegradation of ethanol and/or the BTEX compound with either a zero-order rate constant or a first-order constant. FootPrint can also be used to estimate the surface area of the plume and the concentration at any given point within the plume when the COC is decaying at a constant rate (first- or zero-order) in the absence of ethanol.
Scribe: Environmental Field Data Capture
Scribe is a software tool developed by the USEPA's Environmental Response Team (ERT) to assist in the process of managing environmental data.

Natural Attenuation Software (NAS)
Natural Attenuation Software (NAS) is a screening tool to estimate remediation timeframes for monitored natural attenuation (MNA) to lower groundwater contaminant concentrations to regulatory limits, and to assist in decision-making on the level of source zone treatment in conjunction with MNA using site-specific remediation objectives. NAS is designed for application to ground-water systems consisting of porous, relatively homogeneous, saturated media such as sands and gravels, and assumes that groundwater flow is uniform and unidirectional. NAS consists of a combination of analytical and numerical solute transport models. Natural attenuation processes that NAS models include advection, dispersion, sorption, non-aqueous phase liquid (NAPL) dissolution, and biodegradation. NAS determines redox zonation, and estimates and applies varied biodegradation rates from one redox zone to the next.
Mass Flux Toolkit
The Mass Flux Toolkit, developed for the Department of Defense ESTCP program, is an easy-to-use, software tool that enables users to learn about different mass flux approaches, calculate mass flux from transect data, and apply mass flux values to manage groundwater plumes. The Toolkit presents the user with three main options:
- a module to calculate the total mass flux across one or more transects of a plume, calculate the uncertainty in the calculation, and plot mass flux vs. distance to show the effect of remediation/impact of natural attenuation processes;
- a module allowing users to perform critical dilution calculations for plumes approaching production wells or streams. An additional feature calculates the capture zone of the supply well and compares it to the transect used to calculate the mass flux, directing the user to alter the transect dimensions if the transect does not encompass the capture zone; and
- a module that provides a review of theory and methods of estimating mass flux.
Monitoring and Remediation Optimization System (MAROS)
The Monitoring and Remediation Optimization System (MAROS) software has been developed by Groundwater Services Inc. and the University of Houston for the Air Force Center for Engineering and the Environment (AFCEE) in accordance with the AFCEE Long-Term Monitoring Optimization guide. The software provides site managers with a strategy for formulating appropriate long-term groundwater monitoring programs that can be implemented at lower costs. MAROS is a decision support tool based on statistical methods applied to site-specific data that accounts for relevant current and historical site data as well as hydrogeologic factors (e.g. seepage velocity) and the location of potential receptors (e.g., wells, discharge points, or property boundaries). Based on this site-specific information the software suggests an optimization plan for the current monitoring system in order to efficiently achieve the termination of the monitoring program.
Rapid Assessment Tools (R.A.T.)
Rapid Assessment Tools, or R.A.T., is a standalone Windows application that combines global positioning information from a GPS device with single point or continuous field sample data. R.A.T. stores the sample data with its GPS location in a flat file and plots these results in a dynamic, two-dimensional display in real-time. In the software, data can be viewed with aerial photography, polygon boundaries, and sample designs to allow for immediate data availability, analysis, and use in the field. The collected data can also be exported using standard U.S. EPA data formats such as SCRIBE and ESRI Shapefile. R.A.T. is developed internally by the FIELDS (FIeld EnvironmentaL Decision Support) group in the Superfund Division of the U.S. EPA. The application does not require any licensing or other software to perform data collection.
