这篇文章描述了作者进行的一项研究，旨在检查作为饮用水供应的地表水中贾第虫囊肿、隐孢子虫卵囊和其他微生物浓度、水质和气象参数之间的关系。1996年在新泽西州特伦顿市特拉华河上的一个地点进行了广泛采样。在各种气象条件下进行采样，以确定这些条件的变化是否导致任何与水有关的参数的浓度变化，包括贾第虫囊肿、隐孢子虫卵囊和其他粪便来源的微生物。 共收集了72份寄生虫样本。在寄生虫采样期间，收集额外的抓取样本，以测量粪便来源的其他微生物的浓度。讨论了研究的方法和结果。包括51个参考文献、表格和图表。

This article describes a study conducted by the authors designed to examine the relationship between concentrations of Giardia cysts, Cryptosporidium oocysts, and other microbial, water quality, and meteorological parameters in a surface water used as a potable water supply. Extensive sampling was conducted in 1996 at one location on the Delaware River at Trenton, N.J. Sampling was performed under a variety of meteorological conditions to determine whether changes in such conditions resulted in changes in the concentrations of any of the water-related parameters, including Giardia cysts, Cryptosporidium oocysts, and other microorganisms of fecal origin. Seventy-two parasite samples were collected. During parasite sampling, additional grab samples were gathered to measure concentrations of other microorganisms of fecal origin. The methodology and results of the study are discussed. Includes 51 references, tables, figures.
