PCB TMDL SOURCE ASSESSMENT STUDY, BLUESTONE RIVER WATERSHED
Lott C, Newman A, Norton N, Stewart R, Schneider J. PCB TMDL SOURCE ASSESSMENT STUDY, BLUESTONE RIVER WATERSHED. Virginia Department of Environmental Quality
The Department of Environmental Quality (DEQ) has completed a polychlorinated biphenyl, (PCB) source assessment study for the Bluestone River Watershed in Virginia. This watershed is located within the "Coal Fields" of Virginia and West Virginia where some reports indicate over 300 mining industry related facilities existed. See Figure 1, map of the region. Many of these either used or handled PCB oils. The task of source assessment was made more difficult since many operations have either closed, were located in the remote mountainous valleys and ridges of the watershed, or were operated as home-based industries. The goals of the Bluestone study were to ensure that no site is actively contributing PCBs to the watershed and to provide basis for the PCB Total Maximum Daily Load (TMDL) study required by the Clean Water Act. One of the innovative aspects of the project was the use of semi permeable membrane devices (SPMDs) to determine the contribution of PCB from the major tributaries to the Bluestone.
