I <br />• <br />u <br />summery <br />The surface water section of this report indicates en 800 umho (23 percent) increase in EC <br />between the upstream (HGSD1) end the new downstream (NGSD2) sites during the spring <br />sampling. This increase is no greater then what has been previously observed between <br />XGSD1 end XGSD2 (the old downstream site). This EC increase is mostly due to naturally <br />occurring reline soils in the area end also irrigation return water. TDS values et ell <br />surface water sites were no greater then values previously observed, indicating that no <br />upward trends in salinity are evident. <br />The Ground water section of this report indicates a decrease in TDS values es one <br />progresses downgradient. Also, the number of chemical parameters that exceeded previously <br />observed values for each well also decreased as one progressed downgredient. Drought <br />conditions observed this year may have contributed to the number of ehemieal parameters <br />that exceeded previously observed values. The fact that TDS values decreased downgredient <br />indicates that XGT has an unmeasurable impact on the alluvial system. <br />3 <br />
