底栖无脊椎动物群落作为美国地质调查局国家水质评估计划生态调查部分的一部分进行评估。这些生物数据与物理和化学数据一起收集，以评估水质状况，并了解影响地方、区域和国家水质状况的因素。底栖无脊椎动物群落特征描述的目标是(1)为每个地点制定相关河流河段内的a税清单，以及(2)确定该河段选定生境内的底栖无脊椎动物群落的结构。为实现这些目标，采用了全国一致的方法。该方法提供了场地、范围和生境选择的指导，以及定性多生境采样和半定量单一生境采样的方法和设备。使用适当的质量保证和质量控制准则，以最大限度地提高分析研究单位内和研究单位之间数据的能力。
Benthic invertebrate communities are evaluated as part of the ecological survey component of the U.S. Geological Survey's National Water-Quality Assessment Program. These biological data are collected along with physical and chemical data to assess water-quality conditions and to develop an understanding of the factors that affect water-quality conditions locally, regionally, and nationally. The objectives of benthic invertebrate community characterizations are to (1) develop for each site a list of tax a within the associated stream reach and (2) determine the structure of benthic invertebrate communities within selected habitats of that reach. A nationally consistent approach is used to achieve these objectives. This approach provides guidance on site, reach, and habitat selection and methods and equipment for qualitative multihabitat sampling and semi-quantitative single habitat sampling. Appropriate quality-assurance and quality-control guidelines are used to maximize the ability to analyze data within and among study units.
