• large variation of values from well GE-3 has also been observed with the most recent value <br />at 16. <br />SAR has generally been below one for well GF-1 and at 29 and 70 for wells GF-2 <br />and GF-3 in 1996. These values are thought to be representative of natural conditions in <br />these aquifers at this location. The SAR values for GF-2 and GF-3 could create a problem <br />for irrigation on tight soils. Water from well GF-4 and GF-5 also contains high SAR values. <br />The SAR value for water from well GF-6 has vaned from 0.34 to 6.2. Backfill well GF-7 has <br />exhibited SAR values between 7 and 23 with a most recent average of 8. Limited data <br />from backfill well GF-11 indicates a low value at less than one. <br />SAR values for wells GP-1 and GP-2 were 10 and 3 in 1996. SAR values for well <br />GP-3 are less than 2, while values from well GP-4 are generally between 50 and 100. <br />• Well GP-5 has had SAR values from 22 to 81. SAR values for well GP-6 have <br />been below 4 for the last nine years. The SAR values from well GP-7 are below 1, while <br />the values from well GP-8 have varied from 7.5 to 29. The average SAR from well GP-9 is <br />approximately 2.5. <br />The SAR values from the Pyeatt wells have generally been between 1 and 3. <br />The SAR values from alluvial wells J-1 and COY have been approximately 1 and 1.5, <br />respectively. <br />Values between 4.7 and 6.7 represent the ranges of SAR from well GLUX-1 <br />water. Water from well 81-03A had an SAR value of 84 in 1996. Well GMP-1 had a value <br />of 3.5 in 1996, very similar to the values observed during the previous two years. <br />A SAR of greater than 15 will result in an alkali build-up on most soils and, <br />. therefore, will not be an acceptable irrigation source. Some ground water naturally has a <br />3-11 <br />
