The systems protecting the quality of drinking water in the United States are deteriorating. Many urban water and sewer systems are obsolete. Industrial wastes are imposing a burden on wastewater treatment facilities. In the U.S., outbreaks of water-borne disease are primarily limited to enteritis associated with viruses or Giardia. Issues in the contamination of drinking water by toxic substances include disposal practices, accidental contamination, agricultural runoff and chlorination byproducts. Physicians must support stringent enforcement of water quality standards.
美国保障饮用水质量的系统正在恶化。许多城市供水和排水系统陈旧过时。工业废物给废水处理设施带来负担。在美国，水传播疾病的爆发主要限于与病毒或贾第虫相关的肠炎。有毒物质污染饮用水的问题包括处置方式、意外污染、农业径流和氯化副产物。医生必须支持严格执行水质标准。
