plan so they can run the model to identify appropriate sites for recharge activities(via percolation and/or injection wells),estimate recharge/injection rates(annual and long-term), develop operational parameters(e.g., injection schedule),and identify potential water quality impacts. • Zone 7 staff will perform the running of the existing groundwater model. Task 5.4 Peer Review of Modeling Results • Consultant will perform peer review of modeling results performed by Zone 7 staff. Localized Analysis: The localized analysis will only be performed on the three(3)shortlisted alternatives determined in Task 4.4. Task 5.5 Site Suitability and Aquifer Recharge Rate Analysis • From the literature review(Task 5.1),COL evaluation(Task 5.2)and modeling(Task 5.3), summarize estimates of recharge rates and aquifer capacity,aquifer features affecting injection feasibility,areas potentially suitable for injection based on water supply well locations,and data gaps. • Assess injection well feasibility based on existing literature and modeling results, and recommend candidate sites for bench tests,field investigations,and/or pilot injection well. Task 5.6 Water Quality Desktop Assessment Based on literature review and historical data: • Evaluate potential for mobilization of contaminants(e.g., arsenic,chromium)in the aquifer. • Evaluate potential for precipitation and/or plugging of injection wells. • Identify potential adjustments to water chemistry of injection water to minimize adverse water quality impacts. Task 5.7 TM 5 Draft TM 5 will summarize the results of Task 5. Comments received on the Draft TM will be incorporated into the Draft Report. Task 6-Recommendations: The results from Tasks 4 and 5 will be summarized into a recommended alternative for further investigation. Task 6.1 Discussion of Recommendations • Describe recommended alternative to investigate further. • Develop list of next steps required for implementation of preferred alternatives, including environmental, permitting,modeling,funding, outreach and pilot/field testing.. • Discuss potential impacts of recommended alternatives(for example consider impacts to surface water and identify any potential means of mitigating these impacts). The recommendations will be incorporated into the Draft Report.No separate TM will be prepared. Task 7-Report and Presentations: The Draft Report will be a summary of the previously provided TMs, along with the recommendations.A short Executive Summary document(about 20 pages)will be provided for public/decision-maker use. Consultant will present at up to six Joint Liaison Committee and individual agency Boards on draft/final report,using essentially the same presentation materials. Task 7.1 Draft Report
