XDD specializes in site exit strategy development, remedial alternative analysis, regulatory negotiation, laboratory and field pilot testing, and full-scale implementation of innovative soil and groundwater remediation technologies.

The environmental market has evolved, most sites have been investigated and variety of remediation approaches attempted, yet little progress toward risk reduction and site closure has been made at many sites. Why? There are two reasons 1) a fundamental lack of understanding of the technologies that are being used and 2) ineffective application of generic solutions.

To generate these solutions, XDD retains a talented, committed and experienced staff of scientists and engineers to objectively determine the remedial alternative that best meets our client's needs.

Our clients rely on us to provide the expertise they need to make sound decisions and to develop innovative ways to solve complex problems. To meet this need XDD developed Xpert Solutions™, a rigorous and time tested process, to objectively determine the remedial alternative that best meets our client’s needs.

XDD clients include a wide variety of private Fortune 500 manufacturing companies (serving the automotive, specialty chemical, pharmaceutical, electronic, and machinery industry), petroleum companies, and utility companies involved in gas and electrical generation, transmission and distribution. XDD also serves a number of federal entities including the U.S. Army Corps of Engineers and various branches of the Department of Defense.
