A study was conducted at two beaches on Lake Erie to evaluate the water sampling design for the collection of several microbiological indicator organisms in relation to day, time, and location of collection. The concentrations of these organisms were generally found to vary significantly (P less than 0.05) by the specific time of day and day of weekend that collection took place. However, the concentrations of these organisms did not vary significantly (P greater than 0.05) at various locations in the bathing area. Future studies investigating the health effects of recreational water as related to microbiological variables should be designed to collect water samples at the specific time of day and day of weekend that an individual was exposed. In addition, sampling at various locations in the bathing area should probably be considered for those beaches having poor dispersion of fecal waste sources.
在伊利湖的两个海滩进行了一项研究,以评估与采集日、采集时间和采集地点相关的几种微生物指示生物的水样采集设计。一般发现,这些生物的浓度会因采集发生的具体时间和周末日期而有显著差异(P小于0.05)。然而,在游泳区的不同位置,这些生物的浓度没有显著差异(P大于0.05)。未来关于娱乐用水与微生物变量相关的健康影响的研究,应设计在个体接触水的具体时间和周末日期采集水样。此外,对于粪便污染源扩散不佳的海滩,可能应考虑在游泳区的不同位置进行采样。
