Site remediation of a former steel byproducts waste disposal site, consisted of a slurry cutoff wall, 9 acre multi-layer geomembrane cap, river bank slope stabilization, monitoring well abandonment, gas well abandonment, 200,000 cy of soil fill, building and ancillary demolition, and installation of subsurface utilities for future use.

The project was a one-of-a-kind Superfund site where a multi-discipline sports complex was constructed above the cap. The complex consists of 4 ice hockey surfaces, batting cages, 9 hole golf course, indoor/outdoor golf dome, and restaurant.

The project presented significant challenges in that the work scope was not initially developed and evolved as it progressed. This required significant management and scheduling demands to keep the project on track and within budget.

A full-time health and safety officer (HSO) provided full time technical and administrative support with respect to health and safety and industrial hygiene. The primary contaminants of concern on this site were aromatic hydrocarbons, chlorinated volatile organic compounds, poly nuclear aromatic hydrocarbons (PAHs), pesticides, and PCBs. Real-time monitoring onsite consisted of a photoionization detector (PID) for the volatile organic compounds, combustible gas indicator, oxygen monitor, total dust meter (PDM3), and colorimetric evaluation. Meteorological conditions were tracked daily via the internet collecting weather data which provides current weather conditions (e.g., temperature, wind direction, humidity, precipitation, etc.).
