During a period of five years 1192 water samples from swimming pools were examined for staphylococci and 338 for coliform organisms only. Eighty-nine different pools were sampled.Numbers of staphylococci, estimated by the membrane filtration technique did not bear any significant relation to either bathing load or concentration of free chlorine.Wide variation in the staphylococcal count was observed when different parts of a pool were sampled on the same occasion.The only practicable standard for pool samples in relation to staphylococci would appear to be that these organisms should be absent from 100 ml. water when the pool has been out of use during at least ten hours before sampling if filtration and chlorination are adequate.
在五年期间,对1192份游泳池水样进行了葡萄球菌检测,仅对338份水样进行了大肠菌群检测。共对89个不同的泳池进行了采样。通过膜过滤技术估算的葡萄球菌数量与沐浴负荷或游离氯浓度均无显著关系。在同一时间对泳池不同部位进行采样时,观察到葡萄球菌计数存在很大差异。对于泳池水样中葡萄球菌而言,唯一可行的标准似乎是:如果过滤和氯化处理得当,在采样前泳池至少停用10小时的情况下,100毫升水中不应存在这些微生物。
