The proper collection of precipitation and the accurate measurement of its constituents are important steps in attaining a better understanding of the distribution and effects of acid rain in the United States. One of NAPAP Task Group IV's major programs concerns wet deposition monitoring. One of that program's projects, 4A-15, 'Quality Assurance Support for Wet Deposition Monitoring,' is sponsored by the U.S. Environmental Protection Agency (EPA) to evaluate the sample collection process and provide technical assistance to the NADP/NTN network through a site visitation program. If deficiencies or nonstandard procedures are noted, the site operator and supervisor are notified. All NADP/NTN sites were visited in 1985-1986. A second round of visits began in October 1986, with the goal of visiting approximately one-third of the 200 sites each year over the next three years. The document is a summary report of the findings from the 1989-1990 (Fiscal Year 1990) site visitation program to 67 of the sites of the NADP/NTN network.
