Description

This report investigates the bias and variability of data generated from the Long Term River Network (LTRN) and Tributary Monitoring Network (TMN) programs. In total, 323 field blank samples and 318 duplicate samples were taken from nearly 100 stations across the province of Alberta. Data analyses relate these QC samples to 4,482 provincial LTRN and TMN environmental samples taken between January 2016 and December 2019. There was a wide range of potential contamination (i.e. bias) and variability evident in the parameters monitored in the TMN and LTRN programs. Data end-users should be cognizant of this potential bias and variability in data generated by the LTRN and TMN programs. Parameters with low environmental concentrations, elevated potential for extraneous contamination and/or high variability should be interpreted with caution.

Description

This document recommends quality assurance and control guidelines for all water and sediment sampling programs conducted by aquatic scientists in the Alberta government. To make sure that all data generated on various projects are reliable, quality assurance and quality control must be included in sampling designs for all water quality monitoring projects; quality control data should be interpreted in project reports. While this document is intended primarily for the staff of the Alberta government and their partners and consulting firms conducting studies for the government, it would also be useful for anyone doing water quality studies.
