EPA Monitoring Site: Pier 25 Asbestos Air Monitoring Data
This table shows how much asbestos EPA measured in the air at this site, on the dates and times shown. Daily summaries of this data and how it compares to the level of concern for public health are also available.
EPA can measure asbestos in several ways. For these data tables, EPA is providing measurements in terms of the number of asbestos structures found per square millimeter within our air monitors (structures can include single, overlapping, and bundles of asbestos fibers). The level of concern for asbestos Is based on continuous exposure to more than 70 structures per square millimeter for an extended period. Because cleanup efforts will reduce asbestos levels dramatically over the next several weeks, EPA does not expect people exposed to this amount of asbestos to have increased risks of health problems.
