3.2.53 Other Water-Quality Variables 



Table 3.1 contains the multipurpose water-quality objectives for the East Poplar River at International 

 Boundary, recommended by the International Poplar River Water Quality Board to the UC. The table 

 shows the number of samples collected for each parameter and the number of times over the course of 

 the year that the objectives were exceeded. In the table, multiple replicate samples collected dxuing the 

 aimual quality control exercise are treated as a single sample, but where an objective was exceeded in a 

 rqjlicate sample, this is charged against the single sample noted. As the table shows, all parameters were 

 within the appropriate objectives. Dissolved-oxygen concentration can be low during winter as a result 

 of ice cover and during low-flow conditions in summer as a result of biological activity.
