Brennan embarked on a vital restoration project for the middle section of the Lake George Canal. The primary goal was to protect aquatic organisms by separating them from contaminated sediment through a multi-layer sediment cap.

Initial Site Challenges

Hydrographic surveys revealed areas of varying slope and stability as the first layer of cap material was placed over the canal bottom. These issues were attributed to soft underlying sediment within the canal footprint. The success of this project hinged on effective collaboration between Brennan and the U.S. Army Corps of Engineers (USACE) to address these types of challenges.

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. 

Background on a Burning River

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.
