Abstract The report summarizes the quality assurance activities of the NADP/NTN Quality Assurance Manager in 1990 and 1991. The report documents the accomplishments of the cooperative agreement and makes recommendations for the future operation of the NADP/NTN network. The report summarizes the progress being made by the NADP/NTN monitoring program in implementing its quality assurance plan. The report discusses the validation of field pH measurements, nuances of utilizing the networks PO4(-3) measurements and NADP/NTN siting criteria. Results of a laboratory audit and a compendium of network documentation are also presented. Recommendations emphasize the continued support of the quality assurance manager's role in coordinating quality assurance activities and the need for more support for the gathering and interpretation of quality assurance data.
