Are Biological and Water-Quality Data Collected by Different Methods Comparable?
Control of water pollution became a major environmental priority during the last three decades, and in response, water-quality monitoring has expanded rapidly. Today, Federal, State and local water-resource management agencies make a considerable investment in the collection of water-quality information. A wide variety of procedures are used to collect this information, often depending upon the objectives of the collection effort. A lack of information regarding the quality and comparability of the data collected can result in duplicated sampling efforts or the underutilization of available water-quality information. To address these concerns, studies were done to determine the comparability of water-chemistry and aquatic-invertebrate data collected by different methods in Wisconsin (Lenz and Miller, 1996; Wisconsin Department of Natural Resources and U.S. Geological Survey, 1994).
