Brennan Company received three awards at the [2025 World Dredging Conference & Expo](https://wodcon.org/), hosted by the Western Dredging Association ([WEDA](https://www.westerndredging.org/)) in San Diego, California. These honors underscore our longstanding commitment to safety, environmental responsibility, and meaningful partnerships within the dredging and marine construction industry. Brennan was recognized with the **Safety Excellence Award for a Dredging Project** for our sustained, high-performance safety culture on the Grasse River Remediation Project. Two of our collaborative projects were also honored with **Environmental Excellence Awards** in the remediation category—one for our work on the **Torch Lake Drum Removal Pilot Study****,** alongside [Anchor QEA](https://www.anchorqea.com/), [EA Engineering](https://eaest.com/), and [Honeywell International](https://www.honeywell.com/us/en) —and the other for the **Milwaukee River OU2 Remediation Project,** in partnership with [GEI Consultants](https://www.geiconsultants.com/) and [We Energies](https://www.we-energies.com/).

This multi-year effort addressed legacy pollutants including PCBs, mercury, dioxins, and furans through precision hydraulic dredging, sediment dewatering, water treatment, and the strategic placement of clean sand and habitat materials. "The scale and scope of this project demanded constant coordination, innovation, and respect for the environment," says Project Manager Casey Evenson [Read More](https://www.jfbrennan.com/blog/model-for-environmental-dredging-capping-water-treatment) [**{count-facebook}](https://www.jfbrennan.com/blog/topic/water-treatment#)[**{count-twitter}](https://www.jfbrennan.com/blog/topic/water-treatment#)[**{count-linkedin}](https://www.jfbrennan.com/blog/topic/water-treatment#)[**](https://www.jfbrennan.com/blog/topic/water-treatment#) [![Refinery wastewater dredging and dewatering team](https://www.jfbrennan.com/hubfs/2024%20Pine%20Bend%20Refinery%20-%20Day%20Crew%20Members.jpg) ](https://www.jfbrennan.com/blog/refinery-wastewater-cleanup) ## [How Brennan Delivered Safe, Efficient Refinery Wastewater Cleanup on Schedule](https://www.jfbrennan.com/blog/refinery-wastewater-cleanup) Posted by [Amber Wilson](https://www.jfbrennan.com/blog/author/amber-wilson) on January 30, 2025 ## **Refinery Wastewater Pond Cleanup with Remote Dredging** We recently completed the cleanup of two wastewater ponds for a large producer of transportation fuels. Using a remotely controlled dredge, Brennan removed wastewater sludge from impoundments on the refinery site and dewatered the material with six 2-meter belt filter presses. The remotely controlled dredge added a layer of safety to the project, preventing any health risks that a Leverman might face if exposed to hydrogen sulfide gas released during the dredging process.

It targets the site of a decommissioned manufactured gas plant that once operated in the area.  ## A Collaborative Effort to Clean Milwaukee's River Brennan was selected as the prime contractor for this ambitious project, tasked with dredging contaminated sediments and treating water to restore the river's health. Working closely with GEI Consultants, Inc. (GEI), the project’s design engineers, Brennan is delivering comprehensive solutions that combine environmental restoration, water treatment, and marine construction expertise.

At Brennan, we use treatability testing to develop sound technical approaches for dredged material dewatering, in situ or dewatered dredged material stabilization, and water treatment.  [Treatability](https://www.jfbrennan.com/environmental/treatability) data can be used to price a job more accurately and find cost savings for our clients. Treatability testing allows us to select chemical and mechanical processes for treatment and evaluate less costly alternatives. Here's how we do it.
