Our equipment safely navigates where barges can’t float and where ground equipment can’t trek. Brennan’s specialty amphibious trucks can float fully loaded with a 20-cubic yard payload or be configured to support geotechnical drilling equipment. See our equipment in action with this video!
Island building and habitat restoration have significant environmental benefits, improving aquatic and land-based ecosystems. Working under LS Marine alongside Ramsey County, the U.S. Army Corps of Engineers, Saint Paul District, and the Minnesota Department of Natural Resources, Brennan built up islands at Pigs Eye Lake in Saint Paul, Minnesota.
The project's master plan features seven islands, sand beaches, marsh habitat, and land plantings. We utilized dredged material from the Mississippi River in an environmentally beneficial way to build the islands. Here's how it happened and why it works!
The US Environmental Protection Agency (EPA) and Minnesota Pollution Control Agency (MPCA) signed a project agreement to remediate contaminated sediment in the “ponds behind Erie Pier,” two ponds surrounded by shallow marsh wetlands in the St. Louis River Area of Concern (AOC).
The sediment was primarily contaminated with PCBs, PAHs, mercury, and chromium. Here's how we worked with stakeholders to clean up the sediment and the resulting impact of our work.

The Western Dredging Association (WEDA) presented its 2023 Environmental Excellence Award for Innovation to the Howards Bay Navigation and Cleanup Dredging Project, which is located within the St. Louis River Area of Concern (SLRAOC) in Superior, Wisconsin, and is an integral part of the Port of Duluth-Superior. J.F. Brennan Company (Brennan) partnered with Arcadis and the United States Army Corps of Engineers (USACE) to work on the Howards Bay Remediation Project using innovative methods to secure a positive outcome.
The Cuyahoga Improvement Project in Kent, OH, aims to improve future recreation experiences while protecting existing natural resources. The purpose of our work is to remove areas of petroleum-impacted soft sediments that were deposited decades ago from discontinued industrial practices upstream.
The Cuyahoga River has quite a history: a transportation route; a boundary; an origin for oil, rubber, and steel industries; a power source; and a dumping ground. The river was once 1 of the most polluted in the country. The Cuyahoga has caught fire at least 13 times since the 1860s.
February 6, 2023 — Specialty marine contractor J.F. Brennan Company, Inc. (Brennan) recently finalized the asset acquisition of the dredging and dewatering division of Infrastructure Alternatives, Inc. (IAI). The purchase brings dewatering, water treatment, and treatability testing services into the organization for the first time.
Brennan, working under the U.S. Army Corps of Engineers - Chicago District, executed environmental dredging, sampling, capping, and habitat restoration to remediate an Area of Concern near East Chicago, IN. While complex, the objectives were clear: remediate sediment, mitigate oil sheen, and improve the ecological habitat. Successes and lessons learned during this project will influence operations and remediation efforts for the rest of Lake George Canal.
The University of Wisconsin-La Crosse (UWL) and J.F. Brennan Company, Inc. (Brennan) formally announce their partnership. The agreement between Brennan and UWL will further the educational opportunities for students studying environmental science, equipping them to start on the job right after they graduate.
Brennan is partnering with UWL to support student research and curriculum, and to strengthen the talent pipeline, both locally and within the environmental services industry.
Originally announced by the Western Dredging Association (WEDA).
In recognition of his extensive and outstanding contributions to the dredging community and to the Western Dredging Association, Andrew A. Timmis has been named the 2022 Dredger of the Year at the WEDA Summit & Expo held in Houston, Texas.
Working for many years on the frontlines of environmental dredging, when Mr. Timmis joined WEDA in 2004, he became a member of its Environmental Commission. He helped develop policy for the group and pointed out the need to provide a program for regulators to learn about environmental issues.
