Environmental data is very important in the policy-making process. EPA has contracted lots of projects for monitoring, collecting, and analyzing the environmental data. In order to obtain high quality data, series of control processes should be conducted including sampling, sample storage and handling, instrument calibrations and measurements and data processing. The primary goal of Quality Assurance Project Plan (QAPP) is to ensure that all environmental data, derived by contracted project, are of sufficient quality to support the data"s intended use. An audit program is necessary to make sure that the quality of QAPP has been fulfilled. This project has been conducted to evaluate the data quality of EPA contracted projects. 30EPA projects were audited for 33 times, including 10 re-audited projects. The first seminars were held on 4/6 at EPA , R.O.C 5F First Meeting room. The second seminars were held on 11/22 at International Conference Center, National Taiwan Normal University. One sample plan had been developed by using the format of USEPA 2002「Guidance for Quality Assurance Project Plans」. The goals of this project have been fulfilled after all.
