||The U.S. Environmental Protection Agency (EPA) provides technical assistance to the NADP/NTN network through a site visitation program. Research Triangle Institute, as contractor to EPA, conducts these visits. If deficiencies or nonstandard procedures are noted, the site operator and supervisor are notified. Brief reports are sent to the EPA Project Officer, the NADP/NTN Quality Assurance Manager, and others. In this way, necessary changes can be made promptly. 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 1987-1988 (Fiscal Year 1988) site visitation program to 57 of the sites of the NADP/NTN network. In its present configuration, the network's research and monitoring programs are supported and operated by the U.S. Geological Survey; State Agricultural Experiment Stations; the Departments of Agriculture, the Interior, Commerce, and Energy; and EPA. Additional support is provided by state agencies, public utilities, and industries.
