Description:
The report presents the results of the U.S. Environmental Protection Agency's 1986 National Audit Program by pollutant and by analytical method. Semiannual audits were conducted for Pb, NO3 and SO4 (filter strips) and acid rain, and annual audits were conducted for CO and high volume flow rate. Continuous SO2 monitors were audited throughout the year, such that no monitor was audited more than once. Approximately 40 laboratories participated in each semiannual acid rain audit. Approximately 45 laboratories participated in each NO3 and SO4 audit and approximately 90 laboratories in each Pb audit. Two hundred and thirty-eight CO monitors, 246 SO2 monitors and 1251 high volume flow samplers were also audited. The results for each 1986 audit are presented in tabular form for each concentration level. The overall performance for all participants for each audit conducted since the beginning of the program is also illustrated in a series of figures.
