Public Health Assessment: Final Release. Kalamazoo River/Enbridge Spill: Evaluation of Crude Oil Release to Talmadge Creek and Kalamazoo River on Residential Drinking Water Wells in Nearby Communities (Calhoun and Kalamazoo Counties, Michigan), February 2

摘要

The private drinking water well sampling program has been on-going since the first week of the Enbridge oil spill into the Kalamazoo River in July 2010. Samples have been analyzed for both oil-related chemicals and for non-oil-related chemicals, such as arsenic and lead. Oil-related chemicals were those identified in the heavy crude oil that spilled. More than 150 wells have been sampled, resulting in over 600 individual samples analyzed as part of the drinking water well sampling program. The Michigan Department of Community Health (MDCH) has been reviewing well water data since the program began. This public health assessment summarizes the results of that program from the start of the testing until August 2011. The program is still on-going and is overseen by the Michigan Department of Environmental Quality (MDEQ).
