Were hazardous levels of arsenic found in RFS air samples?
No. As part of the recently established Supplemental Air Monitoring Program , the campus Office of Environment, Health & Safety (EH&S) completed air monitoring for arsenic at various locations at the RFS. In sampling taken to date, air concentrations of arsenic are at or below naturally occurring background levels. The following are results of the recent arsenic monitoring by EH&S: • Aug. 16, 2005, Building 163: Arsenic concentration of 0.098µg/m3, about a hundred times less than the level considered safe by OSHA and in the range of expected background concentrations. • Aug. 16, 2005, Building 175: Arsenic concentration of 0.085µg/m3, about a hundred times less than the level considered safe by OSHA and in the range of expected background concentrations. • Sept. 20, 2005, Building 175: Arsenic levels below detection limit of 0.03µg/m3. • Dec. 6, 2005, Building 478, four locations: Arsenic levels below detection limit of 0.03µg/m3. (On this date, remediation activities were occurring at
