| Abstract |
The report survey visits to the NADP/NTN precipitation collection stations are part of the network's quality assurance program and are coordinated through the NADP/NTN Quality Assurance Director's office. Research Triangle Institute, under contract to EPA, has visited approximately two-thirds of the 200 NADP/NTN sites for the purposes of verifying and documenting that pre-established siting criteria are met; assessing the uniformity of sample collection, analysis, and reporting procedures; conducting quality assurance tests of the operators' equipment and procedures, and providing technical assistance and instruction. Of the approximately 120 sites visited from October 1986 through the present, most are operating within specified guidelines. |
