<br />(,j <br />'<J' <br />C ,-) <br />..-l <br />':) <br />( " <br /> <br />Using the information from Stage 3 Pump Test Wells. we have completed our well <br />spacing for Stage 3. This stage will require about 43 wells and will produce <br />between 30.000 to 36.000 acre-feet of ground water per year. <br /> <br />The area in Stage 3. east of San Luis Creek drain shows water quality comparable <br />to Stage 1-2. while the water from the area west of the drain has a higher average <br />total dissolved solids and sodium +on concentration. <br /> <br />Our salvage well water quality mixing <br />when blending Stages 1-2 and 3" water. <br />2 for the mdxing results. <br /> <br />model shows no problem with water quality <br />Please refer to water quality sheets 1 and <br /> <br />We have established a control system of observation wells in Stages 1-2 and 3 which <br />will provide positive identification of any fluctuations in the water tables. as <br />required by Public Law 92-514. Sec. 102(a). <br /> <br />Short term and long term pump tests show no reduction in existing artesian flows. <br />Section 103 of Public Law 92-514 establishes an operating committee to assure <br />compliance with this and other potential specified adverse effects of.the project. <br />Because this project has highly flexible operational methods (including pumping <br />. rates). the operational constraints prescribed by Public Law 92-514 will be met. <br /> <br />Please refer to tables 1 and 2 for individual well performance in Stages 1-2 and <br />3 respectively. <br /> <br />We are providing the following stage construction comparisons to assist you in <br />making your decision. <br /> <br />DESCRIPTION <br /> <br />CONSTRUct <br />STAGE 1-2 <br /> <br />CONSTRUCT <br />STAGE 1-2 and 3 <br /> <br />Estimated ground water <br />yield (acre~feet/yr.
