Table 1 .--Recommended water-quality objectives and exceedences and the I982 



sampling program (units in milligrams per liter except as otherwise 

 noted) . 



*dissolved form of parameter was determined. 

 Note 



1. March to October, long-term average of flow-weighted concentrations should 

 be < 2.5 mg/L for boron, and < 1,000 mg/L for TDS with a maximum flow- 

 weighted concentration not to exceed 3-5 mg/L for boron and 1,500 mg/L for 

 TDS for any three-month period during this time. 



2. 5.0 (minimum April 10 to May 15) '♦•O (minimum rest of year). 



3. Natural (April 10 to May 15), less than 30 (rest of year). 

 k. 6.5 (minimum) and less than 0.5 above natural. 



5. Total boron data provided by Saskatchewan Environment are included with the 

 Environment Canada dissolved boron values. The respective TDS data bases 

 have also been combined. 



6. The USGS mercury data are being authenticated because of potential sample 

 contamination. The USGS data are, therefore, not available for interpretation.
