"The QA/QC data produced during the first two years of the Canada-Newfoundland Water Quality Monitoring Agreement are presented and analyzed in this report. QA/QC data come from sequential triplicate samples and preservation blanks. The results are evaluated in light of established guidelines for acceptable detection and variability, respectively. Copper, aluminum and total phosphorus were detected in some preservation blanks, while reproducibility was low for total copper, dissolved nitrate-nitrite and total phosphorus in the triplicate samples. The problems observed for copper and for phosphorus suggest the possibility of sample contamination. Still, 88 percent of the total triplicate tests done conformed to acceptable variability"--Abstract, page iii. Includes abstract in French. Water quality Newfoundland and Labrador.
