RMT, Inc.

Contaminated sediment in lakes, rivers, estuaries, and coastal areas presents challenges for industry, stakeholders, and surrounding communities. USEPA estimates that 1.2 to 20 billion cubic yards of contaminated sediment in the United States may require some degree of management with cleanup costs approaching a staggering $5 trillion. Sediment management is clearly one of the most daunting environmental challenges of this century.

The stakes are high. For industry, contaminated sediment in waterways represents a complex environmental liability that is expensive to manage and a real threat to corporate image. For community stakeholders, these sites represent increased human health and ecological risks, a threat to local commerce, and decreased property values.

RMT has been managing complex contaminated sediment sites for over 20 years. While the industry has largely looked to dredging as its primary remedial option, RMT has built an impressive portfolio of projects by focusing on alternative treatment and capping solutions. These innovative approaches shave years off cleanup schedules and can be implemented at a fraction of the average dredging cost.
