ABSTRACT
The continued output of high quality, reliable data depends not only on the use of acceptable analytical methods by competent and conscientious analysts, but also on a prescribed program of regular laboratory quality control. Several basic principles can be used for the comprehensive planning and conduction of a water quality study. One critical issue in planning a water quality study is to insure that representative samples are collected. An important perspective is the overall framework of the monitoring system as well as the individual components. Due to the large number of water quality and sediment parameters and biota testing to be done in a baseline study, it is necessary that appropriate analytical quality control be achieved for the planned laboratory analyses. One of the things which should be considered for a sampling program is the development of a quality assurance plan.
