The Northwest Transformer site (NWT), a 1.6-acre former salvage yard, is approximately 2 miles south of Everson in Whatcom County, Washington. The site is in a rural area and is bordered by low-density residential areas to the north and east, and farmland to the south. The NWT site was used for transformer storage and salvage. Storage and salvage operations were conducted in an onsite barn where PCB-contaminated dielectric fluid was drained from the transformers before dismantling. Transformer casings and associated parts were incinerated onsite, and some of the recovered oil was burned to heat the barn. Spillage and leakage of PCB-laden oil on the ground appeared to have occurred frequently, and some oil apparently was dumped directly into a seepage pit onsite, contaminating soil and possibly ground water. This operable unit includes investigations of ground water and the onsite barn to determine whether either is sufficiently contaminated to merit a subsequent operable unit. The primary contaminant of concern affecting the soil is PCB. The selected remedial action for this are site included.
