In the end, RDBI’s professionalism, expertise and novel approach saved my client a significant amount of money while limiting their liability. They successfully remediated the site and received a “No Further Action” letter without restrictions from the California Regional Water Quality Control Board. The corporate fiduciary was particularly impressed with the work that RDBI provided, and has retained them on several other matters since the inception of their relationship with my client.

“Dr. Jamall is an excellent scientist who also has a thorough knowledge of how to work with the government agencies that oversee environmental cleanups – a rare combination.  His usefulness as a witness is enhanced by his ability to explain complex scientific matters in simple language (flavored with lively metaphors) easily understood by judges and jurors.  In my experience, very few experts can do this.
I highly recommend him.
