| 520 | |a"Under the auspices of the Prairie Provinces Water Board, a quality assurance program was initiated for assessing and improving the comparability of water quality data generated by the Federal Water Quality Branch Saskatoon Laboratory (ECS) and the Alberta, Saskatchewan and Manitoba provincial laboratories. In the first phase of this program, interlab studies are conducted bi-monthly on some 40 parameters involving about 100 analytical procedures. Twelve studies were sent out in the period from September 1986 to August 1987. These studies dealt with analyses of trace metals, major ions, nutrients, and physical parameters in natural and spiked- water samples. The reference water samples are typical of the surface waters found in the various regions. A number of key analyses were identified to be out of control and promptly brought to the attention of laboratory managers to help improve the quality of their data, and to help them to reevaluate their internal quality control procedures"--Executive summary. |
