I also worked with XDD on another site in Midwestern United States where I required consulting services to close a site on a risk-based analysis. My previous consultant had taken the project to a point where final risk-based closure was required, but they did not possess the level of engineering skills provided by XDD. XDD evaluated the collected site data and performed contaminant fate and transport modeling analyses to successfully demonstrate to the regulatory agency that site closure was warranted.Paul Dinardo
