LA CROSSE, Wis., June 14, 2022 ― Engineering News-Record (ENR) published its annual ranking of the largest U.S.-based general contractors, with specialty contractor J.F. Brennan Company (Brennan) making the list with an overall ranking of 351. Brennan is listed as the 5th largest contractor in the hazardous waste sector.

The demand for Brennan’s environmental remediation services has increased year over year on a national scale. Landing at the 5th spot among all hazardous waste contractors, Brennan is in an echelon of its own, as all its projects take place on, under, or alongside bodies of water.

This past year, we made another key asset purchase: the SHERP ATV (SHERP). In addition to our Diamondback Airboat, the SHERP solidifies our durability and efficiency working throughout wetland and marshy areas.

Our experience in wetland habitat restoration began 30 years ago with the Upper Mississippi River Restoration Program (UMRR), the largest restoration program ever undertaken on a major waterway, worldwide.  Since then we have carried out many more restorations along the inland waters of the United States, including restoration after large-scale environmental remediation.  

One of the challenges faced during a remediation, restoration, or construction project located
in the middle of a marshland is access.  Typically contractors have to construct temporary roads to safely reach work areas.  This requirement is costly, especially in the case of an environmental remediation project where all materials have to be removed and disposed of as hazardous waste.  Building temporary roads also negatively impacts the sensitive wetland environment and its inhabitants.   There are other options that can save time and money, while greatly reducing the negative impact on both aquatic plant and animal species.
