The microbiological quality of forest surface waters in the Greenwater River watershed was examined to investigate the influence of heavy motorized camping in an area with no sanitary facilities. Indicator densities increased during weekend human-use periods when compared to weekdays. Increases in indicator densities were also noted downstream from heavily used camping areas when compared to upstream sites. Seasonal, weekly, and diurnal fluctuations in indicator densities were observed. This study suggests that potential health hazards exist in this watershed during periods of human use.
对绿水河流域森林地表水的微生物质量进行了检测,以调查在一个没有卫生设施的地区进行大量机动化露营活动所产生的影响。与工作日相比,周末人类使用期间指示菌密度增加。与上游站点相比,在大量使用的露营地区下游也发现指示菌密度增加。观察到指示菌密度存在季节性、每周和每日的波动。这项研究表明,在人类使用期间,该流域存在潜在的健康危害。
