| Abstract/Description or Keywords |
This study was undertaken to determine the degree to which infrequent single grab samples are representative of the monthly or quarterly mean water quality of the Thompson river in the vicinity of the station at Spences Bridge. It contributes to a continuing evaluation of the overall effectiveness of routine water quality monitoring performed by the Inland Waters Directorate in British Columbia. The study was designed to determine the magnitude of spatial and temporal variability in the concentrations of the following parameters: total phosphorus, nitrate plus nitrite, iron, fluoride, lead, zinc, silica and pH. These parameters were selected because they had shown marked variation in previous quarterly sampling. water quality, monitoring, sampling |
