Occurrence, Distribution, and Trends of Volatile Organic Compounds in the Ohio211 River and its Major Tributaries, 1987-96. National Water-Quality Assessment 211 (NAWQA) Program, National Systhesis on Volatile Organic Compounds (VOCs)

摘要

The report presents an analysis of the occurrence, distribution, and trends of211u001eVOCs in the Ohio River and its major tributaries from 1987 through 1996. Specific 211u001eobjectives of this analysis were to: (1) summarize VOC detections and 211u001econcentrations; (2) determine if concentrations vary spatially and seasonally; 211u001eand (3) determine if trends in concentrations are increasing, decreasing, or 211u001econstant.
