Air Monitoring Results - Daily Summary Printer Friendly Version

Lower Manhattan Construction Command Center - 6/19/2013
The following table records the average concentration of particulate matter accumulated over a 24 hour period.
  Average Exceeds Standard
Based on the national ambient air quality standards for limits for 24 hours (150 µg/m3 for PM 10, 35 µg/m3 for PM 2.5)
 Air Quality Index
  • "Good" The AQI value for your community is between 0 and 50. Air quality is considered satisfactory, and air pollution poses little or no risk.
  • "Moderate" The AQI for your community is between 51 and 100. Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms.
  • "Unhealthy for Sensitive Groups" When AQI values are between 101 and 150, members of sensitive groups may experience health effects. This means they are likely to be affected at lower levels than the general public. For example, people with lung disease are at greater risk from exposure to ozone, while people with either lung disease or heart disease are at greater risk from exposure to particle pollution. The general public is not likely to be affected when the AQI is in this range.
  • "Unhealthy" Everyone may begin to experience health effects when AQI values are between 151 and 200. Members of sensitive groups may experience more serious health effects.
  • "Very Unhealthy" AQI values between 201 and 300 trigger a health alert, meaning everyone may experience more serious health effects.
  • "Hazardous" AQI values over 300 trigger health warnings of emergency conditions. The entire population is more likely to be affected.

Environmental Protection Agency Air Monitoring: Greenwich and Thames Streets

As part of an ongoing program, the U.S. Environmental Protection Agency (EPA), in conjunction with other regulatory agencies, is reviewing air quality sampling results collected by owners of buildings in various locations in the neighborhood south of the World Trade Center (WTC). Two of those locations were 133-135 Greenwich Street and 21-23 Thames Street, where the buildings (two and five stories tall, respectively) were being abated, decontaminated, demolished, and replaced.

For additional information on air monitoring at these locations, please visit the EPA’s website.
