By Patricia L. Toccalino, Barbara L. Rowe, and Julia E. Norman


The U.S. Geological Survey's (USGS) National Water-Quality Assessment (NAWQA) Program recently completed a national assessment of volatile organic compounds (VOCs) in ground water (Zogorski and others, 2006; Moran and others, 2006). This Fact Sheet supplements Chapter 4 of Zogorski and others (2006), and focuses on the occurrence of 44 VOCs detected in samples collected prior to any treatment or blending from 2,401 domestic wells and 1,096 public wells.
