本powerpoint演示文稿首先列出了人类暴露于各种污染物的可接受风险水平，并列出了几种估算风险的尝试 水上风险。它提供了水传播疾病暴发的统计数据，概述了建立风险目标的理由，并提供了题为“风险周期:一个迭代过程”的图表。提供有关隐孢子虫的信息，包括:隐孢子虫成品水监测；CC-PRC法；猪隐孢子虫的检测 过滤饮用水；隐孢子虫风险；季节性风险；隐孢子虫紫外线溶液；允许的紫外线系统停机时间；定义可接受的风险；风险指标；地下水中的病毒和大肠杆菌噬菌体；以及每天和每年的感染风险。包括表格、数字。

This powerpoint presentation begins by listing the acceptable risk levels for human exposure to various contaminants, and lists several attempts at making an estimate of waterborne risk. It provides statistics on waterborne disease outbreaks, outlines the argument for establishing a risk goal, and provides a diagram titled, "The Risk Cycle: An Iterative Process". Information is provided on Cryptosporidium that includes: finished water monitoring for Cryptosporidium; CC-PRC method; detection of Cryptosporidium in filtered drinking water; Cryptosporidium risk; seasonal risk; Cryptosporidium solution of ultraviolet (UV) light; permissible UV system down time; defining acceptable risk; indicators of risk; viruses and coliphages in groundwater; and, daily and annual risks of infection. Includes tables, figures.
