As part of our sediment services, we also provide insurance claim evaluation services for sediment sites. We typically provide third-party review of technical documents, and our field staff has provided on-site observation of sediment investigation and cleanup work. We also assess the reasonableness and necessity of sediment investigation and cleanup expenses, categorize the costs as indemnity versus defense, and estimate future costs to support forecasting for settlement purposes. Our sediment experts are often called on to provide opinions to support insurance litigation.
