While at Green World Science Inc., Mr. Harrington implemented the treatment of the Sweetwater Uranium Pit Lake for Kennecott Uranium Company, part of the Rio Tinto Group. This treatment program resulted in the non-coal award for Excellence in Reclamation for 2001 by the State of Wyoming, and attained stringent targets for restoration of the lake water quality including the surrounding aquifer.
Mr. Harrington presently leads the cleanup of the Globe Smelter in north Denver, addressing groundwater contamination (arsenic, cadmium, selenium and zinc) which had impacted the South Platte River. The Globe site was removed from the NPL (Superfund) list by the United States EPA in December 2014 due to the successful cleanup approach.
Mr. Harrington also manages the in-place remediation of the Cotter Schwartzwalder Mine pool, successfully reducing uranium, molybdenum and selenium by more than an order of magnitude within the mine pool within 4 months of project approval, and decreasing source loading. Mr. Harrington has gained more than a dozen Underground Injection Control (UIC) permits from the United States EPA for in-situ treatment or groundwater restoration projects. Mr. Harrington has successfully negotiated regulatory approvals for innovative treatment (in-situ) approaches at CERCLA/Superfund sites in South Carolina, South Dakota, Colorado, Idaho, Oregon and Arizona.
Mr. Harrington graduated summa cum laude from the University of Idaho in 1996 with majors in Chemistry and Microbiology and completed his graduate work at the University of Idaho in 1998 in Metallurgical Engineering.
