To Whom It May Concern:

During the two years that Eric Roy worked for GZA as a project engineer, he proved himself to be a hard working, dedicated and conscientious employee.

Mr. Roy displayed the ability to effectively plan and execute field sampling and remediation programs and proved proficient in both his knowledge and abilities to carryout the technical programs assigned to him. Mr. Roy often worked long hours over many days during busy times to get the needed work done and did so with very little supervision.

Mr. Roy has demonstrated a clear commitment to the duties assigned him and performed consistently at a high level. I would recommend him for a similar position or one requiring even greater responsibility and level of performance.

I would be happy to further elaborate on my experience with Mr. Roy. I can be reached at (860) 858-3103.

Sincerely,

Christopher FreySenior Project MangerGZA GeoEnvironmental, Inc.Bloomfield, CT
