BIOCHLOR is a screening model that simulates remediation by natural attenuation of dissolved solvents at chlorinated solvent release sites and was developed for the United States Environmental Protection Agency and is hosted at their site. Click the link below to visit the USEPA. EPALOGO. BIOCHLOR on. In the second stage, a detailed conceptual model was developed to identify various contaminant transport pathways and exposure points. The U.S. EPA model and BIOCHLOR was used to assess whether the contaminants are attenuating at a reasonable rate along these transport paths so that MNA can be considered as a. BIOCHLOR is a natural attenuation screening model used to assess the feasibility of monitored natural attenuation (MNA) as a remedial approach for plumes of dissolved-phase chlorinated volatile organic compounds in groundwater. BIOCHLOR is built around the Domenico model, an analytical fate and transport model. Several commonly used analytical groundwater models that address chlorinated solvent plumes are presented below. It is noted that some of the models discussed are not technically “analytical models" but are modeling tools that rely on analytical solutions in their development. 6.5.1.1 Biochlor As described by the USEPA,.

The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting. The U.S. EPA screening model, BIOCHLOR, was used to model the attenuation processes occurring at site. BIOCHLOR is an analytical computer code that is intended for use as a screening-level model to determine if remediation by natural attenuation is feasible at a chlorinated solvent site (Aziz et al., 2000). The code. (e.g., BIOCHLOR [U.S. EPA, 1999b] or ART3D [Quezada et al., 2003]) are capable of solving the general transport equation with specific limitations. Three-dimensional multi-species reactive transport numerical models, such as RT3D, discretize the transport equation and iteratively solve it within a defined numerical domain.
