虽然城市潮湿天气的排放物可能会增加粪便指示细菌的浓度，影响游泳海滩的水质，但并非所有这些细菌都可能来自人类。在这项研究中，非人类粪便指示细菌的贡献进行了量化采样沿海参考海滩在南部加州。在未开发流域的雨水排放口附近的海滩采集样本，并分析总大肠菌群、大肠杆菌和肠球菌。Surfzone样本超过水质阈值的频率在潮湿天气比干燥天气高10倍以上。超出最大
Although urban wet weather discharges may have elevated concentrations of fecal indicator bacteria impacting water quality at swimming beaches, not all of these bacteria may arise from human sources. In this study, the contribution of non-human fecal indicator bacteria was quantified by sampling coastal reference beaches in southern California. Samples were collected at beaches near stormwater discharges from undeveloped watersheds and analyzed for total coliform, Escherichia coli, and enterococci. Surfzone samples exceeded water quality thresholds >10 times more frequently during wet weather than dry weather. Exceedences were greatest
