ABSTRACT

Before establishment of vegetation, soils were intensively sampled in 12-in. (30.5-cm) increments to the underlying sand layer (approximately 2 ft [0.61 m]). Soil samples were analyzed for initial concentrations of contaminants and characterized using standard soil tests. An important aspect of soil remediation research is the routine determination of important chemical and physical properties that affect water, plants, and microorganisms. Soil samples were placed in sterile containers, labeled according to sample location and depth, and transported to Kansas State University (KSU) in coolers for analysis. The contaminated soil adjacent to the phytoremediation study area was treated using bioremediation and removed from the biotreatment cell in the fall of 1996. Soil was sampled to a depth of 2 ft (0.61 m) at the phytoremediation field site using a coring device. The core sample was removed and completely homogenized.
