Improperly disposed hazardous chemical substances are a common source for contamination of drinking water wells. The Agency for Toxic Substances and Disease Registry (ATSDR) and other environmental and public health agencies have recommended that exposure-reduction procedures (i.e., provision of alternative water supplies and construction of new water supplies) be implemented when drinking water wells are contaminated with hazardous substances in concentrations that approach or exceed levels potentially associated with adverse health outcomes in humans. Once these procedures are implemented, the original wells should not be used as sources for drinking water. This report summarizes two cases in which contaminated drinking water wells were being used even though health advisories had been issued to discontinue use of the wells.
不当处置的危险化学物质是饮用水井污染的常见来源。有毒物质和疾病登记署（ATSDR）以及其他环境和公共卫生机构建议，当饮用水井被有害物质污染，且污染浓度接近或超过可能与人类不良健康后果相关的水平时，应实施减少接触程序（即提供替代水源和建设新的供水设施）。一旦实施了这些程序，原有的水井就不应再用作饮用水源。本报告总结了两起案例，尽管已发布健康建议要求停止使用受污染的饮用水井，但这些水井仍在被使用。
