本文报告了对加利福尼亚州洛杉矶县加维水库的进水和出水样本进行的理化和微生物分析。使用计算机化统计软件包调查和分析测量参数之间的相互作用，如颗粒计数和粒度分布、总平板计数、大肠菌群、藻类计数、叶绿素、浊度、铜和铁，以确定反映或可能影响水库水质的重要关系。通过水库中的生物活性降低进水水质，以产生较低的水质- 优质污水。结果表明，藻类与浊度和颗粒物水平的增加有关，可能会增强或支持细菌的活动，包括对细菌进行物理保护，使其免受氯化的影响。包括30个参考文献、表格和图表。

This article reports on physiochemical and microbiological analyses performed on influent and effluent samples taken from Garvey Reservoir in Los Angeles County, California. Interactions between measured parameters such as particle counts and size distributions, total plate count, coliform bacteria, algal counts, chlorophyll, turbidity, copper, and iron were investigated and analyzed with a computerized statistical package to determine significant relationships reflecting or possibly influencing the water quality of the reservoir. The quality of the influent was degraded through biological activity in the reservoir to produce a lower-quality effluent. Results indicate that algae are associated with increased turbidity and particulate levels and might enhance or support bacterial activity, including physical protection of bacteria against the effects of chlorination. Includes 30 references, tables, figure.
