Rhodes, R. AND E. Evans. PRECISION AND ACCURACY ASSESSMENTS FOR STATE AND LOCAL AIR MONITORING NETWORKS, 1984. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/4-86/031 (NTIS PB87111720), 1986.
Description:
Precision and accuracy data obtained from state and local agencies during 1984 are summarized and compared to data reported earlier for the period 1981-1983. A continual improvement in the completeness of the data is evident. Improvement is also evident in the size of the precision and accuracy results reported. Annual results from each reporting organization are also given so that these organizations can compare their results for 1984 with their earlier results and with other organizations. A set of upper and lower limits for precision and accuracy is also proposed -- above these limits corrective action should be taken. A comparison of the precision and accuracy data from the Precision and Accuracy Reporting System and that from the independent performance audit program conducted by the Environmental Monitoring Systems Laboratory is given.
