Problems/Comments
Petroleum contamination from drum spill. Contaminated soil is located on the north side of an unpaved roadway that extends from the west end of Jamie Avenue, directly across the road from the west end of a carport, approximately 80 feet to the west of a wooden bridge that crosses Little Rabbit Creek (approximately 200 feet west of the intersection of Jamie Road and Carl Street). Soil sampling results indicated that diesel range organics (DRO), residual range organics (RRO), benzene, toluene, total xylenes, arsenic, and total chromium exceeded cleanup levels.
