Description:
This report presents the results of the U.S. Environmental Protection Agency's 1983 National Audit Program by pollutant and by analytical method. Semiannual audits were conducted for SO2 and NO2 (bubbler methods), Pb, NO3(-) and SO4(=) (filter strips) and CO (continuous monitors). One audit was conducted on high-volume flow rate. Continuous SO2 monitors were audited throughout the year, such that no monitor was audited more than once. This was the first year that acid rain audits were conducted for U.S. laboratories -- approximately 30 laboratories participated in each semiannual acid rain audit.
