| XDD scientists and engineers have worked on some of the largest vapor intrusion sites in the country and have helped develop EPA guidance on the collection of indoor air and sub-slab air samples. Our adeptness at engineering and implementing cost-effective mitigation systems also goes hand-in-hand with providing exemplary public relations for our clients.
How We Can Help You
