series of pages in Table B-1, starting on Page B-53. The SAR <br />values measured for water from well GA1 and GA2 are low with an <br />average value of approximately 0.3. SAR values for water from <br />well GB2 are typically slightly less than one. The SAR from well <br />GBS has typically been slightly less than 10, while the last four <br />complete analyses in August 1985, September 1986, September 1987 <br />and September 1988 have shown SAR values significantly higher. A <br />definite trend in SAR is not observable. <br />The SAR of water from wells GC1, GC2 and GC3 have been <br />typically near 2. No definite trends are shown by this data. <br />The Twenty Mile Sandstone water from well GD1 has had <br />variable SAR values from 0.5 to 4.5. A trend of these values <br />does not exist, but some of the variation could have been <br />• affected by the length of pumping prior to sampling. The SAR <br />from well GD2 has generally been close to 0.5. Hackfill well GD3 <br />has only had one complete analysis made with an SAR value of 0.4. <br />The early SAR values from well GE1 were close to 20, while <br />most of the more recent values have ranged from 8 to 14 with the <br />1968 value at 4,8. The change in SAR values could be caused by <br />an increased rate of movement of ground water in this area due to <br />the early drawdowns and recent recovering water levels. These <br />SAR values with the TDS of this water should not make irrigation <br /> prohibitive for most soils. SAR values from well GE2 have varied <br /> from 3.6 to 40. The value of 96 for 1987 is significantly higher <br /> than normal. More data is needed with time to determine if a <br /> significant in creasing trend exists. A similar large variation <br /> of values from well GE3 has a lso been observed. <br />3-20 <br />
