Terra Systems Site Evaluation Tools for Anaerobic In-Situ Bioremediation
Terra Systems, Inc. (TSI) uses the ESTCP Substrate Estimating Tool for Enhanced Anaerobic Bioremediation of Chlorinated Solvents to estimate the emulsified vegetable oil (EVO) demand for a particular site. The tool was developed by Parsons Infrastructure and Technology Group (2010) for ESTCP to estimate the substrate demands for sodium lactate, molasses, fructose, ethanol, whey, HRC, soybean oil, and emulsified vegetable oil. The Customer Site Data Worksheet for Anaerobic Bioremediation (in Excel or PDF) should be completed with as much information available and returned to Dr. Mike Lee. He will run the ESTCP Model and make the appropriate recommendations for your site.
The demand is based upon:
- the plume size (length, width, depth, and effective porosity)
- groundwater flow rate
- contaminant concentrations
- competing electron acceptors (dissolved oxygen, nitrate, sulfate, manganese, iron, and methane) and contaminant concentrations
The parameters that typically control the substrate demand are:
- the plume width (perpendicular to groundwater flow) and treatment thickness
- groundwater flow rate
- contaminant concentrations
- and the sulfate concentrations

Once the model is run there are other parameters, such as TOC availability, radius of influence goals and longevity that need to be accounted for. | Anaerobic Demand Customer Worksheet PDF Anaerobic Demand Customer Worksheet Excel |
