J.F. Brennan Company Inc. is an industry leader in several aspects of inland waterway marine construction and environmental stewardship. It was that focus on quality and stewardship that has enabled Brennan to expand into the field of environmental remediation and restoration.
To effectively respond to the difficult challenges faced when remediating a sensitive riverine environment, a company must have a firm grasp on both industry standards and project challenges. At Brennan, we are a leader in developing innovative technologies and processes in the remediation industry. Additionally, Brennan has consistently provided cost-effective remediation solutions while meeting the client’s safety, schedule, and quality expectations.
J.F. Brennan Company has been recognized by the Unites States Environmental Protection Agency (USEPA) Region 5, Great Lakes National Program Office (GLNPO), United States Army Corps of Engineers (USACE), and state agencies as one of the nation’s most resourceful and innovative remediation and restoration contractors. For the past 3 years we have been ranked as one of the “Top 20 Hazardous Waste Contractors” by Engineering News-Record (ENR), an industry-leading publication. This designation was in response to the remediation work we perform yearly on inland waterways throughout the United States.
