Key Projects

CHA Rockwell Gardens Phase 2A Redevelopment, Chicago, Illinois ‐ Coordinated remedial activities including tank removals in accordance with the Illinois Environmental Protection Agency’s (Illinois EPA’s) voluntary Site Remediation Program (SRP). Reviews contractors bid calculations and pay requests. Analyzes data and prepares reports for the SRP and Leaking Underground Storage Tank (LUST) programs.

BP Products North America Inc., Wood River, Illinois ‐ Coordinates semi‐annual groundwater and soil monitoring activities for a phytoremediation / land farming remedial area. Analyzes data and prepares annual current conditions report to the Illinois EPA.

PIG Casting Facility, Gary, Indiana ‐ Conducted a geotechnical and environmental investigation consisting of soil borings and the installation of groundwater monitoring wells. Collected soil samples for environmental and geotechnical analysis including Shelby tubes. Visually classified soil in the field using the Unified Soil Classification System (USCS) per ASTM D‐2487. Oversaw the use of hollow stem auger (HSA) and rotary drilling methods. Assisted in the preparation of a geotechnical report providing engineering evaluations and recommendations regarding the suitability for construction at the site.

La Porte Landfill, La Porte, Indiana ‐ Conducted an investigation of the landfill property for the Indiana Department of Environmental Management (IDEM). Conducted test pit investigation of soil cover thickness, soil sampling, installation of groundwater monitoring wells and groundwater sampling, and soil vapor historical use/operation of different refinery units concentrating on the environmental issues within the main refinery. Prepared a Sampling and Analysis Plan and monitoring well inspection report which were submitted to IDEM.

RUSH University Medical Center Expansion Project, Chicago, Illinois ‐ Coordinated and conducted Phase II investigations and remediation under the Illinois EPA’s voluntary SRP. Coordinated and conducted soil and groundwater sampling and monitoring well installation and abandonment. Analyzed data and prepared reports for the SRP program.

McCormick Place West Expansion, Chicago, Illinois ‐ Conducted Phase I and II investigations for the Illinois EPA’s voluntary SRP and LUST programs.
