美国地质调查局最近完成了对俄勒冈州威拉米特河流域的密集河流质量评估研究。最值得注意的发现是，全面的先进废物处理不能解决满足为威拉米特河制定的严格水质标准的问题。这意味着，僵化的全国性标准和法规可能会导致一些流域出现不必要的支出，而另一些流域则出现不达标的情况。研究还发现，在监测和监测型项目下收集的现有水质数据不足以确定控制河流质量问题的关键因果关系。需要针对当地问题和条件进行密集的概括性调查，以便为作出关键管理决策提供充分的信息基础。
The U.S. Geological Survey recently completed an intensive river quality assessment study of the Willamette River basin, Oregon. The most noteworthy finding was that across-the-board advanced waste treatment was not the answer to the problem of meeting stringent water quality standards established for the Willamette River. This implies that rigid nationwide standards and regulations are likely to result in unneeded expenditures in some river basins and in unachieved standards in others. It was also found that existing water quality data collected under monitoring- and surveillance-type programs are inadequate for defining the critical cause-effect relationships that control river quality problems. Intensive, synoptic surveys keyed to local problems and conditions are required to provide an adequate information base for making key management decisions.
