|Abstract/Description or Keywords||The setting of water quality objectives in priority basins in British Columbia began in 1982.
By the end of 2004, the Ministry of Environment (formerly the Ministry of Water, Land and
Air Protection) had set water quality objectives in 51 areas or basins and updated them in
two, both fresh and marine, throughout the Province. Annual monitoring to check the
attainment of objectives started in 1987. This report presents the results of monitoring done
to check the attainment of objectives in 20 basins in 2004.
The results are summarized in a series of tables. For all Ministry Regions the objectives
were met 90.8 percent of the time in 2004. The findings in 2004 are slightly lower than the
2003 results (92.7%), and similar to previous years when attainment ranged from 95 percent
in 1998 to 77 percent in 1997.
There was not 100 percent attainment because objectives are set in areas where water
quality problems may occur. Monitoring results therefore reflect the state of water quality
in areas affected by human activity rather than in the Province as a whole.
Variables for which objectives were sometimes not met in three or more basins in the 2004
sampling program included fecal coliforms, turbidity, dissolved oxygen and total copper.
