Senior Environmental Engineer

VCard Bio

Mr. Kondziolka is a senior environmental engineer with experience using analytical methods and numerical simulations to solve problems in environmental fluid mechanics.  At Gradient, Mr. Kondziolka works with the Environmental Sciences team to model contaminant fate and transport processes, conduct risk assessments, understand site histories, and develop conceptual site models and remedies.  Before joining Gradient, he worked at the MIT Environmental Fluid Mechanics Laboratory, studying sediment transport and its effects on the evolution of aquatic vegetated ecosystems.

Representative Projects

Water Resources Numerical Modeling:  Managed the production of expert reports filed with the Supreme Court of the United States (SCOTUS) using a large-scale groundwater flow and particle tracking model to support opinions on historical groundwater flow patterns and groundwater-surface water interactions.  Oversaw a modeling team and presented results frequently to the client group.  
Green Chemistry Product Evaluation:  Managed a green chemistry product risk assessment using computational fluid dynamics (CFD) modeling with OpenFOAM and ParaView to support fault tree analysis.  Conducted a site visit in support of model development.

Coal Combustion Residual (CCR) Risk Assessment:  Developed a relative risk framework to assess impacts to water resources from CCR associated with different surface impoundment closure options.  Created and compared two contaminant transport models (MYGRT and EPACMTP) to predict receptor risk from metals.  Modeled infiltration using the Hydrologic Evaluation of Landfill Performance (HELP) model. 

Interstate Chlorinated Solvent Plume Insurance Litigation:  Produced expert reports based on soil, vapor, and groundwater quality data for an insurance cost recovery case. 

Probabilistic Refrigerant Risk Evaluation:  Developed Monte Carlo models to forecast product risk from the introduction of new chemical blends into existing markets. 

Multimedia Site Investigation and Risk-based Corrective Action:  Designed a phased site investigation and risk-based corrective action for a former Manufactured Gas Plant (MGP) site in a commercial/urban area.  Modeled potential vapor intrusion into residences.  Worked with a multi-firm team to produce work plans, remedial investigation/feasibility study reports, remedial action work plans, remedy implementation reports, closure reports, and presentations to regulators.  Managed expert report production to support insurance cost recovery.
