520 |a"Laboratory analyses of animal, water, and sediment samples for various substances provides a snap shot of the condition of the ecosystem. By studying the variation amongst samples over time researchers can begin to gain some insight into the impact of various changes in the study area. The validity of the analytical data measured at trace and ultra trace levels is critical to many of the present day assessments. Results can be questioned due to methodology differences between laboratories, nonadherence to established protocols, lack/poor documentation procedures and differing Quality Assurance/Quality Control (QA/QC) procedures. As the results from the laboratory analyses are taken as absolutes, it is extremely important the Northern River Basins Study (NRBS) have a sufficiently high level of confidence in the results to draw reliable interpretations that could withstand scrutiny. QA/QC programs provide users the assurance that the data are reliable and can be used with confidence"--Study perspective.
