Site Assessments

Phase I ESAs in Four Locations

Federal Aviation Administration (FAA)

Albuquerque and Sheep Springs, New Mexico
Texarkana, Arkansas
Rocksprings, Texas

dse conducted four Phase I ESAs modified to include soil sampling and analysis at four sites located in Albuquerque and Sheep Springs, New Mexico, Texarkana, Arkansas, and Rocksprings, Texas for the FAA. Based on prior experience, the FAA determined that significant levels of hydrocarbon constituents, metals and/or PCB contamination in the soil could have resulted from previous practices.

In order to determine if contamination requiring remediation was present, a Phase I ESA was performed at each site. The investigations included background research regarding past operations and practices as well as sampling of shallow soils at each site. The format and requirements of the investigations were complied with ASTM Standard E1527-05, Standard Practice for ESAs: Phase I ESA Process. In addition to the ASTM requirements, collection and analysis of shallow depth soils were incorporated into the investigations for each site.
