{{#Wiki_filter:ENTRIX, Inc, -Environmental and Natural Resource Management Consultants May 23, 2008 5. Summary and Conclusions 5.1 Well #2 Rehabilitation Rehabilitation work on Well #2 included removal of well pump, surging and brushing to clean casing perforated intervals, removal of accumulated sediment at base of well and redevelopment. Collectively, these maintenance actions along with the new well pumping equipment increase the reliability and pumping efficiency of the well.5.2 Effects of Groundwater Pumping on Diablo Creek The evaluation of the degree of connectivity between Diablo Creek and groundwater pumping at Well #2 suggests that pumping water out of Well #2 will have no effect on Diablo Creek. The water level in the creek is not affected by pumping at the well. If there were connectivity between the creek and the well then one would expect water levels in the creek to drop in response to aggressive pumping or rise in response to the cessation of pumping. Neither response is present. The water quality data collected further corroborates this conclusion with consistent differences in the concentrations of key water quality constituents in water samples collected from the creek and Well #2.5. 3 Recommendations for Groundwater Use The water quality testing and water level monitoring conducted as part of this study*provides an important initial dataset for evaluating several well construction and operational decisions related to both the current production at Well #2 as well as possible future conversion of monitoring wells (Well #4 and Well #5) to production wells.5.3.1 Well #2 Construction, Operations and Maintenance As discussed in Section 4 above, depth-specific water quality testing indicates that the water extracted from the deep production zone is higher quality (i.e., generally lower in constituent concentrations important to plant operations) than water extracted from the shallow production zone. In order to reduce concentrations of certain constituents in extracted groundwater, such as silica, the upper screened portion of Well #2 could be temporarily or permanently sealed. Doing so would improve the quality of pumped groundwater from Well #2. However, this upper productive zone does represent approximately 20% of the flow in the well and if this portion of the well is sealed, DCPP can expect a 10-20 gpm reduction in groundwater production. DCPP Water Resources ReportPae3 Page 38 ENTRIX, Inc. -Environmental and Natural Resource Management Consultants May 23, 2008 5.3.2 Monitoring Wells Based on the pump testing conducted as part of the monitoring well installation program, Well #5 *has a higher specific capacity and better water quality than Well #4, and represents a more viable alternative for future conversion to a production well. However, proximity of Well #5 to the existing production well, Well #2, requires consideration in planning for any future use of this well.Well #4: Additional testing is warranted before consideration of Well #4 as a production well. It has the advantage of being far enough from the existing pumping well that interfering cones of depression are not evident, and it is more distant from the creek than the existing pumping well or Well #5. Water quality is poorer than in Wells #2 and #5, however, and further study of the water quality of individual productive zones, similar to that completed at Well #2 as part of this study, is necessary to determine the most appropriate screen intervals if this well is to be converted to a production well in the future.Well #5: Pumping at Well #2 affected water levels at Well #5, and therefore, any pumping at Well #5 would reduce the water levels at Well #2. Pump set depths at both wells should be examined carefully to determine that there is sufficient depth of water above the pump to account for the drawdown effects of pumping at both wells, particularly in times of lower water levels. Water quality from Well #5 was similar to that of Well #2, and, if deterffnined to be cost effective, a similar plan for sealing the upper portion of the well is worthy of future consideration.

5.4 Monitoring

Program Recommendations Implementation of a water resources monitoring program is recommended to track the state of both the aquifer in the DCPP area and the flows in Diablo Creek. It is recommended that water levels at the Creek and the wells, groundwater production, and water quality are monitored on a regular basis. Weekly surface and groundwater level and groundwater production measurements are recommended, particularly during the dry season.In support of this, two data-recording water level probes were installed in wells to ensure continual collection of water level data. The water level probes were installed in Wells #2 and #5 for the duration of the second constant rate pumping test. After the test was terminated, the probes were left in place and programmed to record the water level twice daily. Tracking the water level trends over months and years will provide valuable information on the groundwater resource and help ensure forecasting of groundwater conditions and optimal management for improved reliability. A complete draft of the DCPP Surface and Groundwater Monitoring Plan, which outlines specific monitoring recommendations as well as program management responsibilities, is included in Attachment E.DCPPWate Reourcs ReortPage 39 ENTRIX, Inc. -Environmental and Natural Resource Manageme'nt Consultants August 13, 2008 DRAFT Attachment A: Well 4 Documentation

Summary and Conclusions 5.1 Well #2 Rehabilitation Rehabilitation work on Well #2 included removal of well pump, surging and brushing to clean casing perforated intervals, removal of accumulated sediment at base of well and redevelopment. Collectively, these maintenance actions along with the new well pumping equipment increase the reliability and pumping efficiency of the well.5.2 Effects of Groundwater Pumping on Diablo Creek The evaluation of the degree of connectivity between Diablo Creek and groundwater pumping at Well #2 suggests that pumping water out of Well #2 will have no effect on Diablo Creek. The water level in the creek is not affected by pumping at the well. If there were connectivity between the creek and the well then one would expect water levels in the creek to drop in response to aggressive pumping or rise in response to the cessation of pumping. Neither response is present. The water quality data collected further corroborates this conclusion with consistent differences in the concentrations of key water quality constituents in water samples collected from the creek and Well #2.5. 3 Recommendations for Groundwater Use The water quality testing and water level monitoring conducted as part of this study*provides an important initial dataset for evaluating several well construction and operational decisions related to both the current production at Well #2 as well as possible future conversion of monitoring wells (Well #4 and Well #5) to production wells.5.3.1 Well #2 Construction, Operations and Maintenance As discussed in Section 4 above, depth-specific water quality testing indicates that the water extracted from the deep production zone is higher quality (i.e., generally lower in constituent concentrations important to plant operations) than water extracted from the shallow production zone. In order to reduce concentrations of certain constituents in extracted groundwater, such as silica, the upper screened portion of Well #2 could be temporarily or permanently sealed. Doing so would improve the quality of pumped groundwater from Well #2. However, this upper productive zone does represent approximately 20% of the flow in the well and if this portion of the well is sealed, DCPP can expect a 10-20 gpm reduction in groundwater production. DCPP Water Resources ReportPae3 Page 38 ENTRIX, Inc. -Environmental and Natural Resource Management Consultants May 23, 2008 5.3.2 Monitoring Wells Based on the pump testing conducted as part of the monitoring well installation program, Well #5 *has a higher specific capacity and better water quality than Well #4, and represents a more viable alternative for future conversion to a production well. However, proximity of Well #5 to the existing production well, Well #2, requires consideration in planning for any future use of this well.Well #4: Additional testing is warranted before consideration of Well #4 as a production well. It has the advantage of being far enough from the existing pumping well that interfering cones of depression are not evident, and it is more distant from the creek than the existing pumping well or Well #5. Water quality is poorer than in Wells #2 and #5, however, and further study of the water quality of individual productive zones, similar to that completed at Well #2 as part of this study, is necessary to determine the most appropriate screen intervals if this well is to be converted to a production well in the future.Well #5: Pumping at Well #2 affected water levels at Well #5, and therefore, any pumping at Well #5 would reduce the water levels at Well #2. Pump set depths at both wells should be examined carefully to determine that there is sufficient depth of water above the pump to account for the drawdown effects of pumping at both wells, particularly in times of lower water levels. Water quality from Well #5 was similar to that of Well #2, and, if deterffnined to be cost effective, a similar plan for sealing the upper portion of the well is worthy of future consideration.

5.4 Monitoring

Program Recommendations Implementation of a water resources monitoring program is recommended to track the state of both the aquifer in the DCPP area and the flows in Diablo Creek. It is recommended that water levels at the Creek and the wells, groundwater production, and water quality are monitored on a regular basis. Weekly surface and groundwater level and groundwater production measurements are recommended, particularly during the dry season.In support of this, two data-recording water level probes were installed in wells to ensure continual collection of water level data. The water level probes were installed in Wells #2 and #5 for the duration of the second constant rate pumping test. After the test was terminated, the probes were left in place and programmed to record the water level twice daily. Tracking the water level trends over months and years will provide valuable information on the groundwater resource and help ensure forecasting of groundwater conditions and optimal management for improved reliability. A complete draft of the DCPP Surface and Groundwater Monitoring Plan, which outlines specific monitoring recommendations as well as program management responsibilities, is included in Attachment E.DCPPWate Reourcs ReortPage 39 ENTRIX, Inc. -Environmental and Natural Resource Manageme'nt Consultants August 13, 2008 DRAFT Attachment A: Well 4 Documentation
