The US Environmental Protection Agency prepares Health Advisories (HA) for drinking water contaminants. The HA provide technical guidance to public health officials or other interested groups on many aspects concerning drinking water contamination. The HA contain information on the chemistry, health effects, analytical methods and treatment technologies for specific contaminants. In addition, the HA include a risk assessment section which provides concentrations of the contaminant in drinking water that are not anticipated to cause adverse, noncancer health effects for 1 or 10 days or for longer exposures. Because the HA include risk assessments for less than lifetime exposures, they are useful when accidental spills occur or when regulatory limits are temporarily exceeded. The guidance documents are updated when new information becomes available that would change the previous conclusions.
美国环境保护局针对饮用水污染物制定健康咨询意见（HA）。这些健康咨询意见就饮用水污染的诸多方面向公共卫生官员或其他相关团体提供技术指导。健康咨询意见包含特定污染物的化学性质、健康影响、分析方法及处理技术等信息。此外，健康咨询意见还包括一个风险评估部分，该部分给出了预计不会在1天、10天或更长时间接触情况下对健康造成非癌症不良影响的饮用水中污染物浓度。由于健康咨询意见包含的是少于终生接触情况的风险评估，所以在发生意外泄漏或暂时超出监管限值时很有用。当有新信息可用且会改变先前结论时，这些指导文件会进行更新。
