State of the Environmental Industry | June 2019

Posted by Andrew Timmis on June 20, 2019

We’re nearly halfway through 2019, and unless you’ve been in a cave or under a rock, you understand that the environmental market is exploding right now. I have been in the environmental industry for 32 years (wow that’s a long time), and I do not believe I have ever experienced this much activity. The size, scopes, and complexities of our current projects are overwhelming. J.F Brennan Company (Brennan) is extremely fortunate to have a very busy, robust workload this year with some exciting projects underway, and more that are set to begin once fish windows open. Based on our own surplus of work and activity, I wanted to share my observations and discuss the current state of the environmental community from a dredging contractor’s perspective.

The Basics of Using Polymers on Dredging Projects

Posted by Dillon Hogan on October 16, 2018

Why Add Polymers?

 

One of the biggest challenges on a dredging project is managing the water that is excavated and transported with the sediment. On hydraulic dredging jobs where sediment and water are pumped through a pipeline as a slurry, water can account for 90+ percent of the volumetric flow. After the slurry reaches the disposal area, the water must be separated from the sediment, collected, and often clarified or treated. This process must happen as fast as the water is being pumped, which for a 12-inch cutterhead dredge could be 5,000 gallons per minute.

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.

The Most Effective Way to Build Sand Covers and Caps

Posted by Nathan Kainz on May 15, 2018

Capping is an integral part of the remediation of a water body. As the benthic community generally lives on the bottom of a lake or river, these micro-organisms are a key piece of the ecological food chain. They are also very sensitive to contaminants, and any level of exposure can greatly reduce their population. Putting a cover, or cap, of clean material such as sand, engineered materials, or stone over the bottom of the waterway can provide the clean environment in which the benthic community can flourish while trace amounts of contaminants are left to safely decompose underneath.
