1985年秋天，在纽约伍德斯托克的供水系统中发现了高浓度的石棉，这是在一次例行的管道挖掘作业之后发现的。这种石棉的来源是石棉石棉（AC）管，这种石棉管已严重变质，很容易用手将管段折断。虽然随着空调管道从系统中移除，石棉浓度迅速降低，但在1986年夏季测量到的浓度高达49 MFL。在整个采样期间，即使浓度降至1 MFL以下，伍德斯托克水样的特征是纤维长度、宽度和质量都比在纽约州无问题地区采集的纤维大得多。包括17个参考资料、表格、图表和照片。

High concentrations of asbestos were found in the water supply system of Woodstock, New York, following a routine pipe-tapping operation in the fall of 1985. The source of this asbestos was asbestoscement (AC) pipe, which was so deteriorated that sections of pipe could be easily broken by hand. Although asbestos concentrations decreased rapidly as AC pipe was removed from the system, concentrations as high as 49 MFL were measured during the summer of 1986. Throughout the sampling period, even when concentrations fell below 1 MFL, Woodstock water samples were characterized by fibers with much larger lengths, widths, and masses that those collected in nonproblem areas across New York state.
