The water quality from the discharge points has been consistent with no trends indicated. 

 A summary of the more frequently tested parameters during 1991 is provided in Table 

 4.2. Included in this table are the average and standard deviation of the results from 

 January 1 990 to December 1 991 . TDS and boron results for several discharge points are 

 illustrated in Figures 4.2 and 4.3 for 1990 and 1991 to show the consistent results of the 

 pumpwell analysis.
