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. Coordinated and conducted soil and groundwater sampling and monitoring well installation and abandonment. Oversaw remediation activities including tank removals. Analyzed data and prepared reports for the SRP and LUST programs. Prepared budget and billing forms for reimbursement from the LUST program.
Henkel Corporation, Buffalo, New York ‐ Prepares work plans for monitoring of a high vacuum extraction system. Analyzes soil, groundwater, and discharge data to evaluate system effectiveness and plan for additional remedial action (chemical oxidation, biotreatment, monitored natural attenuation). Assists in preparation of reports for the New York State Voluntary Cleanup Program/Brownfields Cleanup Program.
IDOT Peoria to Macomb Corridor Study, Illinois ‐ Maintained database of public meeting attendees and public comments concerning the Corridor Study. Compiled mailing lists for newsletters.
The Premcor Refining Group, Inc., Blue Island, Illinois ‐ Completed a water well survey for the Illinois EPA. Compiled historic public and private well information from the Illinois State Geological Survey (ISGS) and Illinois State Water Survey (ISWS) databases.
