Contaminated sites and sediments
Industries, waterfront developers, resource managers, and site owners face many challenges as they strive to remediate or control environmental impacts at contaminated sites. The process of addressing legacy pollution can be complex, because of large volumes of sediments or soils, multiple contaminants and sources, and the length of time required for assessment and implementation. Furthermore, costs for remediating and restoring rivers, lakes, estuaries, floodplains, and other land sites can sometimes be staggering—up to hundreds of millions of dollars.
Clients need cost-effective solutions supported by sound science, as well as liability protection. In many cases, long-term pumping and treating or widespread dredging of contaminated sediments to “remove” pollutants may be ineffective. Other less expensive alternatives like bioremediation, natural attenuation, or capping can often achieve similar or better results.
Since 1975, LimnoTech has helped clients select, design, and implement cost-effective strategies to achieve their restoration goals. During this time, we’ve continued developing new scientific modeling and analytical tools to analyze problems and explore innovative restoration approaches.
For contaminated sites and sediments, LimnoTech offers:
- Assessment of the nature and extent of the problem, dynamics of the system, and risks
- Evaluation of remedial alternatives using field investigations, models, and experience
- Innovative, state-of-the-art approaches to allocations support
- Superior knowledge of the regulations
- Outstanding credibility with regulating agencies
We help our clients thoroughly understand their contaminated sites—and make the best decisions.
"“LimnoTech has been an essential and strategic partner working directly with us and our clients to solve some of the most scientifically-challenging marine and freshwater contaminated sediment problems in the U.S. and other countries . . . I cannot imagine any complicated water resource or sediment management project proceeding without LimnoTech on the team."
