THE POND CLOSURE & SITE CLEANUP PROJECT
A Midwest manufacturing site has an environmental problem.  It is located on an old factory property with multiple areas of concern. Troy Risk’s geologists, scientists and engineers developed a great plan to clean up the site’s old wastewater treatment ponds, capture oil in contaminated soil and ensure protection from PCBs for workers, neighbors and other stakeholders.
  • New innovative dewatering techniques to remove the oily sludge, and transport it for disposal.
  • An underflow slurry curtain to capture and recover the oil floating under the factory.
  • A complete risk assessment and institutional controls to ensure that the property users and neighbors are safe.
