(GEOSCIENCE) was tasked with conducting four predictive model runs for the Rialto-Colton Groundwater Basin. This technical memorandum evaluates Mure water level effects of extending status quo pumping for 36 years into the future as compared to water level conditions resulting from all entities in the Basin adhering to the pumping restrictions of the 1961 Decree for that 36-year period. Predictive runs will also be used to evaluate the water level and perchlorate concentrations as a result of adding artificial recharge at the Cactus Basin pond~ and simultaneously extracting that volume through existing wells throughout the Rialto-Colton Basin. 1.2 Project Location The Rialto-Colton Groundwater Basin (Rialto-Colton Basin or Basin) is in western San Bernardino County, California, approximately 60 miles east of Los Angeles (see Figure 1}. The Rialto-Colton Basin is the subject of significant groundwater management issues . Such issues include perchlorate and TCE contamination that has impacted and continues to impact the Rialto-Colton Basin, requiring extensive groundwater investigation and remediation efforts. The water purveyors that manage the Rialto-Colton Basin also believe that due to significant drawdown in the Rialto-Colton Basin water levels, efforts will be required to recharge the Rialto-Colton Basin using other water sources. Such serious issues require a groundwater model that all stakeholders in the Basin can rely upon. 1.3 Background The first numerical groundwater model of the Rialto-Colton Basin was developed in 2001 by Woolfenden and Koczot of the United States Geological Survey {USGS) to simulate the aquifer response to artificial recharge. Geo-Logic Associates, Inc. (GLA), on behalf of the County of San Bernardino, developed a groundwater flow and solute transport model of the upper Rialto-Colton Basin to evaluate the groundwater impacts originating from the County Remedy Area in 2007. The most recent County/GLA model update was conducted in 2010. CH2M Hill, on behalf of the United States GEOSCIENCE ~ 1 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Pred ictive Model Runs of the Rialto-Colton Basin Groundwater Model l·Dec-15 Environmental Protection Agency (USEPA), adapted the County/GLA model in 2010 during preparation of the Remedial Investigation/Feasibility Study (RI/FS) and Record of Decision (ROD). In 2012, CH2M Hill extended the model domain throughout the Rialto-colton Basin. ERM-West, Inc. (ERM), on behalf of the Emhart Industries, Inc. (Emhart), updated the USEPA/CH2M Hill 2012 model by incorporating data from relevant stakeholders. The ERM/Emhart draft modeling report was submitted to the USEPA in April 2013. There are some agreements and disagreements among these existing models. GEOSCIENCE was tasked with developing a Joint Groundwater Model (JGWM) that is spatially and temporally refined from that of the various existing models of the Rialto-Colton Basin. Specifically, the tasks included: • Task 1: Prepare for and Attend Kickoff Meeting (Including Preparation of Modeling Work Plan) • Task 2: Review the Existing Rialto-Colton Groundwater Models • Task 3: Develop a 3-D lithological Model and Refine Model Layers • Task 4: Conduct Water Balance Analysis • Task 5: Recalibrate Model with Refined Model layers, Cell Size, Stress Period and Recharge and Discharge Terms, and Perform Sensitivity Analysis • Task 6: Develop and Calibrate Solute Transport Model for Perchlorate • Task 7: Develop and Run Predictive Model Scenarios • Task 8: Prepare Summary Report • Task 9: Prepare for and Attend Bi-Weekly Progress Conference Calls The JGWM contains a flow model component as well as a solute transport model component to evaluate potential impacts of various groundwater management and water quality remediation program scenarios on existing perchlorate plumes. The calibration of the JGWM represented a combined effort which incorporated input and comments from the Rialto-Colton Technical Advisory Committee (TAC). During the process of the solute transport model calibration, the TAC decided to extend the solute transport model calibration from 2000 through 2011 to 2000 through 2014. The purpose of the model extension was to include the dry hydrology that occurred during the past three years such that the effects on groundwater level elevations, flow directions, and seepage velocity would be included in the model. In addition, the model was calibrated to recent perchlorate data collected from wells PW-13, PW-14, CPW-16 and CPW-17, which show the GEOSCIENCE ~ 2 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 recent extent of the perchlorate plumes. The flow model calibration period was also updated from 1945 through 2011 to 1945 through 2014 in order to generate input data for the solute transport model. The JGWM flow model was successfully calibrated through a steady state calibration for 1945 and a transient calibration from 1945 through 2014. The transient calibration used annual stress periods from 1945 through 1969 and monthly stress periods from 1970 through 2014. The JGWM steady state flow model calibration has a global budget error of 0 .0096 while the transient flow model calibration has a global budget error of 0.02%; a global budget error of less than 1% is considered acceptable. The acceptable model calibration Is also reflected by a relative error of 4 .3% for the steady state calibration and 6.2% for the transient calibration. Common modeling practice is to consider a good fit between measured and model-calculated water levels if the relative error is below 10% (Spitz and Moreno, 1996). The JGWM solute transport model was successfully calibrated from 2000 through 2014 using a monthly stress period. The solute transport model calibration has relative error of 2.7% which is well below the recommended modeling error of 10%. This technical memorandum covers Task 7 of this study-to develop and run predictive model scenarios prior to the final report on all aspects of developing and running the Rialto-Colton JGWM. 1.4 Multi-Agency Cooperative Technical Effort The predictive model runs process of the JGWM for the Rialto-Colton Groundwater Basin was a cooperative technical effort involving: • Representatives of participating parties, including San Bernardino Valley Municipal Water District (Valley District), West Valley Water District (West Valley or WVWD), Goodrich Corporation (Goodrich), City of Rialto, and City of Colton; • Representatives of the County of San Bernardino's consultant GLA; • Representatives of participating parties ' consultant Balleau Groundwater, Inc. (BGW); and • Technical advisors representing the USEPA, USEPA's consultant CH2M Hill, and the USGS. Collaboration by these representatives to develop the predictive model runs of the Rialto-Colton Groundwater Basin was achieved through participation at project conference calls, model workshops, and reviewing and commenting on a draft technical memorandum (TM). A total of five conference calls and two model workshops were held during the model calibration periods. GEOSCIENCE ""V7'" 3 Valley Di strict/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 GEOSCIENCE presented preliminary results of the predictive model runs to the TAC at the 23-Jul-15 model workshop. The comments received from the TAC on preliminary results were incorporated in the draft Predictive Model Runs TM issued on 11-Sep-15 (GEOSCIENCE, 2015). From 11-Sep-15 through 25-Sep-15, comments on the draft Predictive Model Runs TM were received including: • September 21, 2015 from United Technologies Corporation (UTC; see Appendix Al for comments and GEOSCIENCE's responses), • September 22 , 2015 from the City of Colton (see Appendix A2 for comments and GEOSCIENCE's responses}, • October 9, 2015 from the County of San Bernardino/GLA (see Appendix A3 for comments and GEOSCIENCE's responses). These comments are incorporated in this final Predictive Model Runs TM. GEOSCIENCE ~ 4 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 2.0 PREDICTIVE MODEL DEVELOPMENT Based on the analysis of historical precipitation, the 36-year period from January 1978 through December 2013 was selected for the hydrologic base period for the predictive model scenarios. This base period covers both wet and dry hydrologic cycles and the average precipitation is approximately the same as the long-term average (see Figure 2). By applying the 1978-2013 hydrologic conditions (natural recharge, groundwater inflow and outflow, plus pumpage) to the model for the next 36 years (2015-2050), the model should duplicate water levels from 1978-2013 (Figure 3). Having real hydrologic data that is representative of the changing wet and dry conditions for a specific area and being able to use those conditions in a predictive model allows the model to incorporate local and temporal variations; using just average conditions often misses these area-specific variations. To run the future predictive model runs, the pumpage for the predictive period from 2015-2050 was replaced with two different pumping rates from the existing wells within the model area. These yearly pumping volumes were further adjusted based upon the predicted water levels for each year, as specified by the water level triggers outlined in the 1961 Decree (see Figure 4). Table 11ists the assumptions for the predictive model scenarios . Tables 2 through 9 show the total pumping for the four major pumpers inside the 1961 Decree area for the predictive runs. Tables 10 and 11 list the total pumpage for those within and outside the 1961 Decree area for the predictive model runs. 2.1 Predictive Scenarios Based on 1961 Decree Pumping and 1978-2013 Hydrologic Conditions In Scenario 1, the pumping rates for all the wells within the area were subjected to the conditions of the 1961 Decree (see Figure 5 and Tables 2-11) for all wells except for the Fontana Water Company (Fontana or FWC) wells. For the Fontana wells, the actual average pumping rates from 2010-2014 were applied to each of the predictive years In the future. Table 12 shows the annual groundwater pumping for each individual well under Scenario 1 conditions. in Scenario 2, the pumping rates for all the wells within the area were subjected to the conditions of the 1961 Decree (see Figure 5 and Tables 2-11) and applied to each of the predictive years in the future . Table 13 shows the annual groundwater pumping for each individual wells under Scenario 2 conditions. In this study, it is assumed that deductions in pumping rates were applied to all the extr<!ction rights per the 1961 Decree (i.e., 3,900 acre-ft/yr for Colton, 4,366 acre-ft/yr for Rialto, 6,104 acre-ft/yr for WVWD, and 920 acre-ft/yr for Fontana). This assumption is slightly different than the actual statement (i .e., paragraph 7) in the 1961 Decree where it stated there were certain amounts-890 acre-ft/yr for Colton, 1,520 acre-ft/yr for Rialto, 510 acre-ft/yr for WVWD and 370 acre-ft/yr for Fontana-not subject to the pumping rate deductions. GEOSCIENCE roughly estimated the difference in pumping caused by this GEOSCIENCE ~ 5 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 discrepancy in the assumption and it was only 690 acre-ft/yr for Scenario 1 and 140 acre-ft/yr for Scenario 2 . Total pumping within the Basin was 28,400 acre-ft/yr for Scenario 1 and 22,448 for Scenario 2 . The anticipated impacts due to this discrepancy will be very small. 2.2 Predictive Scenarios with Artificial Recharge at Cactus Basins Two additional scenarios (Scenarios 3 and 4) were developed to evaluate the basin-wide effects of artificial recharge at the Cactus Basins. The location where this recharge was applied between April and October (Cactus Basins 3 and 3A) is shown in Figure 1. The annual quantity of water input to the artificial recharge basin was determ ined by the availability of State Water Project (SWP) water for each year corresponding to the historic conditions in the predictive year. The hydrology was subdivided into five categories based on the availability of SWP water (Figures 5 and 6) including wet, above normal, normal, below normal, and dry. These five categories are delineated based on the exceedance probability of annual Table A allocation for SWP water. For example, annual Table A allocation for SWP water with an exceedance probability between 0% and 20% was classified as a wet year. If the annual Table A allocation for SWP water exceedance probability was between 20% and 40%, it was considered an above normal rainfall year. An exceedance probability of 40% to 60% was a normal year. A year with between 60% and 80% of exceedance probability is considered a below normal year. Finally, an annual Table A allocation of SWP water with an exceedance probability between 80% and 100% was considered a dry year. The following table summarizes the initial annual amount of artificial recharge under various local hydrologic conditions for Scenarios 3 and 4.

As shown, the average annual recharge was 2,670 acre-ft/yr during the 36-year simulation period. For the purpose of this study, it was assumed that the recharge volume rate was not affected by evapotranspiration, since evapotranspiration is expected to be very small. GEOSCIENCE ""7'"" 6 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 Once the amount of recharge was applied for each year, a percentage of that total volume recharged was apportioned as potential additional pumpage to each of the wells belonging to the City of Colton, the City of Rialto or WVWD within the 1961 Decree boundary. The distribution of this pumpage was based upon the percentage of water rights specified in the 1961 Decree . In Scenario 3, annual artificial recharge was applied to Cactus Basins 3 and 3A based on the recharge table above. Total pumping from each well was the total from Scenario 1. For all City of Colton, City of Rialto and WVWD wells, a percentage of the annual Cactus Basins recharge was added to each well as additional pumpage-regardless of predicted water levels and decreed pumping restrictions (see Table 15). In Scenario 4, the annual artificial recharge was applied to Cactus Basins 3 and 3A based on the recharge table above. Total pumping from each well was the total from Scenario 2. For all City of Colton, City of Rialto and WVWD wells, a percentage of the annual Cactus Basins recharge was added to each well as additional pumpage-regardless of predicted water levels and decreed pumping restrictions (see Table 16). 2.3 Initial Conditions for the Predictive Runs Initial water levels for all of the predictive runs were taken to be Basin water levels for the year 2014 (at the end of the flow model calibration runs). The initial perchlorate concentrations for all of the predictive scenario runs were the perchlorate concentrations throughout the Basin at the end of 2014- as determined from the solute transport calibration runs. 2.4 Additional Perchlorate Mass Loading In areas where significant contamination exists, the effect of significant water level rises into -a zone where the contaminant may have been previously bound-up by a less permeable material. In addition, a significant downward percolation of rainfall infiltration can cause contaminants to be transported out of the less permeable material and down to the water table. To account for these conditions, mass balance evaluations can be made such that the increase in contaminant concentrations can be matched with the transport model. As part of the Rialto-Colton solute transport modeling effort, a mass loading analysis was conducted at wells where there have been documented increases in concentration resulting from water level changes. Figures 8 and 9 illustrate how the mass loading analysis was developed by first establishing a relationship between the observed water levels and mass loading for the for the 2000-2014 period . The GEOSCIENCE ~ 7 Valley Dist rict/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 model results were then evaluated to see where other mass loading relationships may be located . The relationships from the evaluations found in the 2000-2014 time period was then applied back to the 1978-1999 period to establish the mass loading for the hydrology from 1978-2013 that could be applied to future scenarios using the hydrology for the 2015-2050 predictive runs. This approach is consistent with comments originating in TAC workshops and is considered a conservative approach. As discussed by Mr. Ron Falta (City of Colton), the mass loading from same level storm events would tend to decrease over time. This decrease happens because when the water level goes up and reaches a new high elevation, the perchlorate mass stored in the vadose zone is washed out, resulting in a corresponding increase in concentration. After this initial water level rise, there will be less perchlorate mass left in the vadose zone. Therefore, if water levels rise up to or below the height of the previous water level rise, the perchlorate concentration will still increase -but at a Jesser rate than that observed previously. However, in order to evaluate the worst case for perchlorate contamination, future mass loading amounts are assumed to be the same as the historical ones without any reductions. For each predictive scenario, two solute transport model runs were made : one without mass loading and one with the mass loading developed from the calibration run. These two bookend solute transport model runs were used to evaluate the i mpacts from recharge in the Cactus Basins. It is Important to note that the solute transport scenario without mass loading was not intended to neglect that mass loading occurs, but rather to identify and understand the difference that mass loading makes. GEOSCIENCE ""V7"" 8 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 3.0 RESULTS OF PREDICTIVE MODEL RUNS FOR THE FOUR SCENARIOS Based upon the specified pumping quantities for each scenario and the artificial recharge volumes added to Scenarios 3 and 4, predictive model runs were made and water levels and perchlorate concentrations were recorded for many of the wells within the Basin. 3.1 Water Level Changes from the Predictive Model Runs Figure 10 shows the predicted water level at the index wells based upon the Baseline Scenarios (Scenarios 1 and 2). The hydrograph for Scenario 1 (based upon the assumption that all parties except Fontana are held to the 1961 Decree pumping restrictions) rose about 30 ft in the early years and declined about 35 ft below the 2015 level by 2050. The hydrograph for Scenario 2 (based upon the assumption that all water producers, including Fontana, are restricted to the 1961 Decree pumping restrictions} shows a greater rise in the early years and a 2050 water level closer to the initial 2015 water level. Annual pumping during this time period was closer to the safe yield of the Basin. The difference in water levels between the two scenarios ranges from 20 to 35ft, with higher water levels for the predictive runs where all parties adhere to the 1961 Decree. Figure 11 shows the predictive water levels for all four predictive scenarios. The dashed green and orange lines show the effects of Baseline Scenarios 1 and 2 from Figure 10 and the solid lines represent the water levels from Scenarios 3 and 4. The later two have recharge at the Cactus Basins added into the model and simultaneously extracted from the Basin through extra pumping allowances at Project wells belonging to the companies who paid for the recharged water. The overall effect of the recharge in the index wells is less than a 3-ft rise in water levels at the end of the 36-year period (2050). Figure 12 shows the inflow and outflow terms for the average annual groundwater budgets for the Basin under each predictive model run . The only real differences in the budget boxes for the four scenarios are changes in groundwater pumping and artificial recharge of imported water. This change results in corresponding changes in the underflow to North Riverside Basin and changes to groundwater storage . Representative hydrographs for wells in model layers 1, 2, 3, 5 and 6 are shown in Figures 13 through 17. These hydrographs show similar rises in water levels for both scenarios where wells within the 1961 Decree area are subjected to the 1961 Decree restrictions (Scenarios 2 and 4) as well as for those where all pumpers except Fontana were held to the 1961 Decree restrictions (Scenarios 1 and 3). For layers 1 and 2 (Figures 13 and 14) there is essentially no change in water level between the four scenarios (only one line is visible as the orange and green lines are on top of each other). In model layer 3 (Figure 15), there is a very minor difference in water levels between Scenarios 3 and 4 . In layers 5 and 6 (Figures 16 GEOSCIENCE """""'V7* 9 Valley District/West Valley/Goodrich/ City of Rialto/City o f Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 and 17), the water levels for Scenarios 3 and 4 have differences of as much as 10ft. The only difference between the two scenarios is that the Fontana wells were not kept to the pumping stipulated by the 1961 Decree . These differences in water levels were more obvious upgradient of the Cactus Basins than below the ponds. 3.2 Changes in Perchlorate Concentrations from the Predictive Model Runs Examining perchlorate concentrations in wells from the predictive model runs gives a good idea of the effects of recharging water at the Cactus Basins. Figure 18 shows the predicted perchlorate concentrations of Well EMW-03B located northwest of the spreading grounds. The concentration In the well is predicted to rise to about 65 micrograms per liter {~L) in 2016-2017 and then decline rapidly to about 5 11g/L in 2020 and trace amounts in 2035. The difference in concentrations with or without recharge is negligible as both Scenarios 2 and 4 plot on top of each other. Figure 19 for Well 1S/SW-3AS and 1S/5W-3A6, which is located near the spreading grounds, shows a very pronounced difference between the Baseline Scenario 2 and Project Scenario 4 with recharge at the Cactus Basins. The significant dilution of the perchlorate is evident from the much faster decline in the perchlorate concentration around 2016-2017 from 130 to almost 0 IJ.g/L as a result of the recharge. In the Baseline Scenario (Scenario 2), the concentration stays up at 175 IJ.g/L until about 2020 and then declines to trace amounts around 2022. Figure 20 shows predicted perchlorate concentrations in the Rialto 6 well located near the spreading grounds. The orange line on this figure shows that as the concentrations decline, the concentration for perchlorate in Scenario 4 {or Project scenario) is less than that for Scenario 2 (Baseline scenario} due to the dilution effect of the additional water recharged at the ponds. The perchlorate concentrations at Wells CPW 16A through 160 and PW-148 and PW-14C (Figures 21 and 22) show the effect of the recharge diluting the perchlorate and also moving the plume farther southeast. The two concentration mounds and troughs in the vicinity of both of these wells is a result of plume movement in the area plus the dilution effect from artificial recharge. The perchlorate concentrations in Wells CPW-17C and 170 (Figure 23} further illustrate the dilution effect on groundwater downgradient from the recharge ponds; concentrations in Scenario 4 are much lower than concentrations in Scenario 2. After 2040, the perchlorate concentrations under Scenario 4 drop to two-thirds of the value under Scenario 2, but are still well above the drinking water standard. GEOSCIENCE ~ 10 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 Figure 24 shows the perchlorate in Well Colton-15, located just east of the Unnamed fault that crosses the Basin perpendicularly to the groundwater flow direction. The character of the plume shows that the dilution has not had as much effect here as it did farther upgradient and to the northwest. At this point, the concentration of perchlorate reaches approximately 40 ~g/l and the dilution effect is not nearly as significant as that in wells to the northwest. Figures 25 through 31 show perchlorate concentrations through time for Scenario 2 and Scenario 4 in pumping wells Rialto-3 , Miro-2, Miro-3, F-49A, F-13A, F-138, and EW-1 . Figures 32 through 53 show perchlorate concentrations through time for Scenario 2 and Scenario 4 in monitoring wells M-1, M-2, M-4, M-5, M-6, N-13, N-18, N-20, and F-32 . In general, the anticipated impact on the Western Plume from Project recharge will not be significant. Dilution effect from the Project recharge is observed in wells EW-1 and M-4. Perchlorate concentrations will slightly increase under the Project recharge conditions in wells M-5, M-6, and N-18-located northwest of the Cactus Basins. These slight increases are most likely the result of recharge downstream slowing down the plume movement upstream of the recharge ponds. Attached Appendices B1 through B4 show the chemographs of perchlorate concentrations for additional target wells within the Basin. Appendices Bl and B2 compare concentrations at the wells based on Scenarios 1 and 3 while Appendices B3 and B4 compare concentration at the wells based on Scenarios 2 and 4. 3.3 Plume Changes Over Time from Flow and Dilution from Artificial Recharge Figures 54 through 59 illustrate the movement of the major plumes throughout the area for model layers 3, 5, and 6 over various time frames (Initial, Model Year 13, Model Year 21, and Model Year 36 or the end of model run). Examination of the plumes for the area based upon Scenario 2 and Scenario 4 for the specified years show how the concentrations move through the Basin from northwest to southeast. The decreases in the size of the plumes and decreased concentration in each layer between the snapshots for Scenario 2 and Scenario 4 best illustrate the minor dilution effects of the artificial recharge. Appendices C1 through C4 show additional plume shapes over time for different layers with and without additional mass loading. Appendix C1 shows the plume shapes for Scenarios 1 and 3 without mass loading for model layers 3, 5 and 6. Appendix C2 shows the plume shapes for Scenarios 2 and 4 with mass loading for layers 3, 5, and 6. Appendix C3 shows the plume shapes for Scenarios 2 and 3 for layers GEOSCIENCE ""V7" 11 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 3, 5, and 6 with no mass loading; and Appendix C4 shows the plume shapes for Scenarios 2 and 4 for layers 3, 5, and 6 with mass loading. 3.4 Particle Tracking Analysis In this study, MODPATH was used to calculate the particle tracking zones for each of the pumping wells during the predictive modeling period. MODPATH is a post-processing package developed to compute three-dimensional flow paths (i.e., particle tracking) using output from the groundwater flow model. MODPATH does not take into account dispersion, retardation, or half-life decay. The results of MODPATH simply provide an Indication of the direction and rate of groundwater flow. Figures 60 through 63 show the results of particle tracking analysis for Scenarios 1 through 4, respectively. In general, the sizes of capture zones are very similar under no Project recharge conditions and Project recharge conditions. For the remediation wells (i.e., Wells EW-1, Rialto-3, F-49A, Miro-2, Mlro-3, and Rialto-G), the change in the widths of capture zones caused by Project recharge are not significant. This observation indicates that the Project recharge at Cactus Basins will barely have any impacts on the plume remediation. GEOSCIENCE ~ 12 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 4.0 FINDINGS Analysis of the predictive model runs for the four scenarios Illustrate that recharging approximately 2,700 acre-ft/yr of water at Cactus Basins 3 and 3A while simultaneously extracting that same volume through wells throughout the Basin has a very minimal effect on water levels or perchlorate concentrations throughout the Basin. Results of the analysis Include the following. • The baseline predictive model runs (Scenarios 1 and 2) show water level differences of 20-35 ft between the runs when all parties adhere to the 1961 Decree and when all parties except Fontana adhere to the 1961 pumping restrictions. The higher water levels represent the lower pumping conditions of Scenario 2 when all parties adhered to the 1961 Decree. • Water levels increased up to 2-ft in the vicinity of the recharge ponds as a result of recharge versus no recharge. Water level increases due to recharge were Imperceptible elsewhere in the Basin. • Slight increases (2-5 ~L) in perchlorate concentrations were seen in wells upgradient and northwest of the recharge ponds (where existing concentrations are already 70-200 ~L) as a result of recharge versus no recharge. These slight increases are most likely the result of the recharge downstream slowing down the plume movement upstream of the recharge ponds. • Much earlier declines of perchlorate concentration from 175 to 0 ~g/L were seen immediately downgradient of the ponds as a result of dilution of the groundwater from artificial recharge at the ponds. • Some downgradient wells show slight increases in perchlorate for the runs with the additional recharge earlier than they do without the recharge. However, the magnitude of perchlorate concentration is still generally the same as without the recharge -only the timing of the peak is different. • Perchlorate concentrations downgradient of the recharge ponds decrease with recharge versus no recharge as a result of dilution from recharged water. • There is no significant change in the size of the geographic footprint of the perchlorate plumes with or without recharge at the Cactus Basins, but concentrations are decreased from dilution. • The calibrated model overestimates or underestimates the perchlorate concentrations in some wells near the boundary of the Eastern Plume (e .g., N-2S, EMW-5A, EMW-38, and PW-11). This GEOSCIENCE ~ 13 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 result is caused by minor differences in flow direction between those simulated in the flow model and actual conditions. • Even if the perchlorate concentration at one of the calibration wells is slightly above or below the historic conditions, because the model used the same initial conditions for both the base scenario and Project scenario, any resulting change in concentrations between the two runs is reflect ive of only the differences in the No Project and the Project scenario runs. • The model predictive results show no anticipated significant groundwater contamination impacts from the proposed Project, suggesting that no additional mitigation measures are needed beyond those that have been previously planned and are in place . GEOSCIENCE "'""7""" 14 Valley District/West Valley/Goodrich/ City of Rialto/City of Colton Predictive Model Runs of the Rialto-Colton Basin Groundwater Model 1-Dec-15 5.0 ASSUMPTIONS AND LIMITATIONS While groundwater models are useful tools for evaluating water levels, basin management strategies and remediation strategies, all models are a simplified approximation of a complex hydrogeologic system. As such, there are certain built-in assumptions. The accuracy of the predictions made by the model is therefore dependent on the simplifying assumptions used. Assumptions for the JGWM include the following: • Groundwater flow is assumed to be horizontal within each model layer and vertical between layers, • The layers are horizontally isotropic, • Changes In the groundwater storage in the model layers occur Instantaneously with changes in hydraulic head, and • Recharge, like that from return flow, reaches the water table immediately (i.e., no time delay for travel time through unsaturated materials).
