An Analysis of Contaminated Well Water and Health Effects in Woburn, Massachusetts
分析了1979年发现的两口受污染井水与沃本市儿童白血病、围产期死亡等健康问题的统计关联，发现部分阳性关联，但未发现与流产、低出生体重等的关联。
In 1979, two of the eight municipal wells servicing Woburn, Massachusetts, were discovered to be contaminated with several chlorinated organics. Shortly afterwards, the town was found to have an elevated rate of childhood leukemia. Using recent information about the space—time distribution of water from the two contaminated wells, we find positive statistical associations between access to this water and the incidence rates of childhood leukemia, perinatal deaths (1970–1982), two of five categories of congenital anomalies, and two of nine categories of childhood disorders. We find no associations with spontaneous abortions, low birth weight, or the other categories of congenital anomalies and childhood disorders. This article discussed these results and other features of the data relevant to their interpretation.
