SAR has generally been below one for well GF1 and above 30 <br />• and 40 at wells 6F2 and GF3, respectively. These values are <br />thought to be representative of natural conditions in the <br />aquifer. SAR values for well GF3 from 1986 to 1987 are <br />significantly higher than past values. The SAR values for GF2 <br />and GF3 could create a problem for irrigation on tight soils. <br />Water from well GF4 and GFS also contains high SAR values. The <br />SAR value for water from well GF6 has declined gradually and <br />additional monitoring with time is needed to establish a good <br />mean for this well. 8ackfill well GF7 has exhibited SAR values <br />between 7 and 23. Only three data points are available from welt <br />GF7. One complete analysis was done on new backfill well GF11 <br />with an SAR of 0.39. <br />SAR values for wells GP1 and GP2 are approximately 11.6 and <br />• 5.5, SAA values for well GP3 are less than 2, while values from <br />well GP4 have shown a very wide range from 47 to 177. <br />Well GPS has had SAR values from 38 to 69. SAR values for <br />well GP6 have shown some variance, with values at or below 26. <br />The SAR value from the Pyeatt wells has generally been <br />between 1 and 3. A slight decreasing trend could exist in well <br />P3. The SAR values from alluvial wells J1 and COY have been <br />approximately 1 and 2, respectively. <br />Water from well 81-03a has contained SAR values of near 200. <br />More monitoring is needed to establish good values for each of <br />these. <br />3.5 OTHER CONSTITUENTS <br />• The major constituents other than the carbonates are <br />3-21 <br />
