How we do it.

Unlike other firms in southern California, we maintain a variety of internal equipment to support investigations and surveys that range from standard grain size analysis to full suite toxicological analysis.

Experience

Our staff have leveraged their collective years of experience working on sediment projects and improved on the methods, accuracy, and costs associated with these types of projects regionally.

Effective Solutions

We routinely work with large engineering firms, local, state, and federal agencies, and private clients looking for consultation or support for their sediment related management concerns.
