Excerpt: . . . 2. 0 REQUIREMENTS 2. 1 CO-OPS Data Quality Assurance Requirements For every scientific or technical investigation, a means must be provided to assure that the data used, are sufficiently accurate to support the objectives of the investigation. A mechanism to attain such accuracy is the Data Quality Assurance ( DQA ) plan. Such a plan provides for the selection and certification of measurement devices, the specification of procedures to be used in both field and laboratory operations, and processing and evaluation of the data collected. Evaluation of the data includes the specification of acceptable limits of accuracy and the definition of the causes of errors. The DQA plan also provides for continuous monitoring of the data collection process to see that specified procedures are followed, that error analyses are being used to control data quality, that data meet program objectives, and that data quality is known at all times. This document provides information and guidance so that data collection activities in marine measurement programs can be effectively planned, controlled, and reported. Recommendations are made on the type and organization of activities needed for collecting data compatible with the intent of such programs. The guidance in this document is general; it can be used to develop a DQA plan for any type of measurement program. It is presented in a logical sequence for developing a DQA plan. Once a DQA plan is completed and has been reviewed by management, it becomes an integral part of the measurement program and provides a systematic way to control the uncertainty of the collected data. 2. 2 National Water Level Network Requir. . .
