Sediment and Aquatic Ecosystems

Rivers, streams, ponds, lakes and other wetlands present unique and often costly challenges for environmental professionals and owners of facilities that abut them. Defining impacts associated with past or current operations and if unacceptable risks are identified how to best solve the problem are but two of these challenges. We have a diverse staff of professionals with backgrounds in engineering and the sciences who can address the complexities and uncertainties associated with these natural systems. Loureiro provides comprehensive characterization services, and, if necessary, remedial action planning. We work with regulatory agencies to get their buy in and approval, and we perform sediment remediation and ecosystem restoration. Loureiro's track record is clear; we meet the challenges, identify cost-effective and sensible solutions for our clients and we implement them.

  • Source identification and source control
