Stormwater runoff is now a major contributor to the pollution of coastal waters in the United States. Public agencies are responding by requiring stormwater monitoring to satisfy the National Pollutant Discharge Elimination System stormwater permit. However, studies to understand the utility of the current programs or to improve their usefulness have not yet been performed. In this paper, we evaluate the land-use-based program, the industrial stormwater permit program, and beach water-quality monitoring in the County of Los Angeles, California, to determine if the results will be helpful to planners and regulators in abating stormwater pollution. The utility of the program has been assessed based on the programs' ability to accurately estimate the emissions for different classes of land use. The land-use program appears successful, while the industrial monitoring program does not. Beach water-quality monitoring suffers from a lack of real-time monitoring techniques. We also provide suggested improvements, such as sampling method and time, and parameter selection.
雨水径流如今是美国沿海水域污染的主要来源。公共机构正在采取应对措施，要求进行雨水监测以满足国家污染物排放消除系统的雨水排放许可要求。然而，尚未开展旨在了解当前项目效用或提高其有效性的研究。在本文中，我们评估了加利福尼亚州洛杉矶县基于土地利用的项目、工业雨水排放许可项目以及海滩水质监测，以确定这些结果是否有助于规划者和监管机构减轻雨水污染。该项目的效用是根据其准确估算不同土地利用类别排放量的能力来评估的。土地利用项目似乎取得了成功，而工业监测项目则不然。海滩水质监测缺乏实时监测技术。我们还提出了一些改进建议，例如采样方法和时间以及参数选择。
