    Dr. Boroumand is an environmental engineer with a background in groundwater hydrology, fate and transport of contaminants in porous media, and numerical modeling.  Prior to joining Gradient, Dr. Boroumand completed his doctoral degree at Tufts University, where he researched the use of innovative tools to study the structure and characteristics of chlorinated solvent source zones.  He applied numerical modeling and statistical approaches to interpret partitioning tracer test results and obtain information about the source of DNAPL contamination in the subsurface environment.  Dr. Boroumand also has a technical background in geotechnical engineering and has worked in consulting engineering as a civil engineer for several years.

      Representative Projects

      Surface and Groundwater Interactions: Used regional-scale groundwater flow models to simulate aquifer-surface water interactions and estimate the associated impacts of groundwater consumptive use on stream flows in drought conditions. This analysis was used in support of a water rights dispute between two states tried before the US Supreme Court.

      NAPL Migration in Fractured Bedrock: Developed a theoretical framework for evaluating the physical constraints on mobilizing manufactured gas plant (MGP) tar in fractured bedrock. This framework can be used to characterize the mobility of MGP tar in fractured bedrock up front in the site remediation process to help define appropriate remediation technologies and cleanup goals.

      Multiphase Flow Analysis: To assess the potential risk related to gas migration to potable aquifers, evaluated the physical conditions that lead to gas leakage along the casing of oil and gas wells. Analyzed available methane migration data sets to identify the potential pathways and gas migration regimes.

      Contaminant Fate and Transport Analysis: In support of claims related to insurance coverage, performed analysis to evaluate the potential for a relationship between historical application of herbicides and more recent detections in groundwater and surface water in multiple states across the US.

      Contaminant Fate and Transport Modeling: For a Superfund site, reviewed the collected groundwater data and site characterization information obtained over the past two decades and modified and recalibrated the original numerical groundwater and solute transport model to describe the existing PCE plume more realistically and optimize the remediation system, accordingly.

      “Green and Sustainable Remediation (GSR)” Analysis: For a coal powered utility company, modeled the site and supply chain activities associated with alternative coal ash impoundment closure options to evaluate the life cycle, environmental, and safety impacts associated with each option.

      Remedial Investigation: Evaluated sources of mercury contamination and remedy appropriateness at a former industrial building complex to be redeveloped. Also prepared exhibits to provide an evidence-based framework for assigning liability to responsible parties.
