Description: The data and network operating procedures from the precipitation and snow sampling networks in the AOSERP area of Alberta were reviewed and assessed. The data was first reformatted into NAQUADAT format and then quality assured by several screening procedures including outlier tests, simultaneous high concentration tests, and anion-cation ratios. A computer tape for the reformatted and screened data was produced. The data were also analysed statistically by factor analysis and other procedures to determine its rel iability and level of confidence. A major deficiency found was the poor and highly variable collection efficiency for precipitation data which precluded conducting any detailed analysis. Since the determination of the environmental impact of two major pollution sources on precipitation quality in the study area was a primary project objective, poor collection effi ci enci es did not permit satisfaction of this objective. Extensive evaluation was also made of the operational procedures for both the field and laboratory methods. While laboratory methods were generally found to be adequate in the later years 1983, 1984, field procedures, particularly the method of sampling, were determined to be inadequate to meet the operationa 1 objectives of the network. Other major defi ci enci es were the absence of a documented quality assurance plan, the generally low level of quality control in network operations, and a poor level of documentation for all aspects of network operation. These factors limited the ability to perform a comprehensive evaluation of the data. Recommendations for mitigating these problems are suggested in the report.

Heidorn Concord Scientific Corporation for RESEARCH MANAGEMENT DIVISION Alberta Environment RMD Report 86-36 1985 vii EXECUTIVE SUMMARY Although precipitation and snowpack samples have been collected in a monitoring network in the oil sands of Alberta since 1976 and the monitoring data collected have been the subject of several reports that have dealt with various aspects of the data and network operations, the overall assessment of the network and the data have not been systematically evaluated. Concord Scientific Corporation was commissioned to conduct such an evaluation through: 1.
Transformation of the existing free format data into a consistent format; 2.
Evaluation of the data by application of screening procedures and assessment of field and 1aboratory procedures of the networks operation; 3.
Statistical analysis of the quality assurance and quality control data generated throughout the networks operation; 4.
Statistical analysis of the monitoring data to determine spatial and tempora 1 trends and interparameter relationships; and 5.
Preliminary assessment of the likely impact of future emissions on precipitation chemistry in the study area. The study yielded the following results: Database Conversion The data have been converted into a format consistent with the NAQUADAT database.
The raw data have been transformed into a fixed format file, screened, and the resultant categories of data placed in separate files.
The attributes of the screened data have been recorded in a flag file that has a format similar to that in the raw and screened arrays.
Considerable merging of data was necessary since there were often replicate records containing different types of information about The multiplicity of files and their inconsistent the same sample. formats pre...
