Our experience in wetland habitat restoration began decades ago with the Upper Mississippi River Restoration Program (UMRR), the largest restoration program ever undertaken on a major waterway worldwide.  Since then, restoring marshes, wetlands, and highly sensitive ecosystems along inland and coastal waters nationwide has been a main initiative.

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.
