Secondary sewage effluent and renovated water from four wells at the Flushing Meadows Wastewater Renovation Project near Phoenix, Arizona, in operation since 1967, were assayed approximately every 2 months in 1974 for viruses and enteric bacteria during flooding periods. No viruses of Salmonella sp. were detected in any renovated well water samples, and the numbers of fecal coliforms, fecal streptococci, and total bacteria were decreased by about 99.9% in the renovated well waters after the wastewater was filtered through about 9 m of soil.
自1967年起运行的位于亚利桑那州凤凰城附近的法拉盛草地废水净化项目中,对二级污水排放物以及来自四口井的回用水进行了检测。1974年,在洪水期大约每两个月检测一次病毒和肠道细菌。在任何回用水井水样中均未检测到沙门氏菌属病毒,经过约9米厚的土壤过滤废水后,回用水井水中的粪大肠菌群、粪链球菌和总细菌数量减少了约99.9%。
