目标.本研究探讨了城市化引起的暴雨径流的公共健康风险规模。我们编制了城市处理过的饮用水的浊度数据，作为选定的美国城市的潜在风险的指标，并比较了水传播疾病和预防措施的估计成本。美国其他城市的湍流水平与威斯康星州密尔沃基和宾夕法尼亚州费城的疾病水平相似。水传播疾病的估计年度成本与改善饮用水处理和雨水管理所需的长期资本投资相当。虽然需要更多的成本和效益数据，但减少径流和相关污染的雨水管理似乎对以最低成本保护公众健康有意义。
Objectives. This study investigated the scale of the public health risk from stormwater runoff caused by urbanization.Methods. We compiled turbidity data for municipal treated drinking water as an indication of potential risk in selected US cities and compared estimated costs of waterborne disease and preventive measures.Results. Turbidity levels in other US cities were similar to those linked to illnesses in Milwaukee, Wis, and Philadelphia, Pa. The estimated annual cost of waterborne illness is comparable to the long-term capital investment needed for improved drinking water treatment and stormwater management.Conclusions. Although additional data on cost and effectiveness are needed, stormwater management to minimize runoff and associated pollution appears to make sense for protecting public health at the least cost.
