This paper estimates the health costs at Superfund sites for conditions associated with volatile organic compounds (VOCs) in drinking water. Health conditions were identified from published literature and registry information as occurring at excess rates in VOC-exposed populations. These health conditions were: (1) some categories of birth defects, (2) urinary tract disorders, (3) diabetes, (4) eczema and skin conditions, (5) anemia, (6) speech and hearing impairments in children under 10 years of age, and (7) stroke. Excess rates were used to estimate the excess number of cases occurring among the total population living within one-half mile of 258 Superfund sites. These sites had evidence of completed human exposure pathways for VOCs in drinking water. For each type of medical condition, an individual's expected medical costs, long-term care costs, and lost work time due to illness or premature mortality were estimated. Costs were calculated to be approximately $330 million per year, in the absence of any remediation or public health intervention programs. The results indicate the general magnitude of the economic burden associated with a limited number of contaminants at a portion of all Superfund sites, thus suggesting that the burden would be greater than that estimated in this study if all contaminants at all Superfund sites could be taken into account.
本文估算了超级基金场地中与饮用水中挥发性有机化合物(VOCs)相关疾病的健康成本。通过已发表的文献和登记信息确定了在VOCs暴露人群中发病率过高的健康状况。这些健康状况包括:(1)某些类型的出生缺陷;(2)泌尿系统疾病;(3)糖尿病;(4)湿疹和皮肤疾病;(5)贫血;(6)10岁以下儿童的言语和听力障碍;(7)中风。利用发病率过高的数据估算了居住在258个超级基金场地半英里范围内的总人口中出现的额外病例数。这些场地有证据表明存在饮用水中VOCs完整的人体暴露途径。对于每种医疗状况,估算了个人的预期医疗成本、长期护理成本以及因疾病或过早死亡导致的工作时间损失。在没有任何修复或公共卫生干预计划的情况下,计算得出每年的成本约为3.3亿美元。结果表明了与所有超级基金场地中一部分场地的有限数量污染物相关的经济负担的大致规模,因此表明如果考虑到所有超级基金场地的所有污染物,负担将比本研究估计的更大。
