Groundwater Flow Modeling. Utilize the East-Central Florida Transient (ECFTX) Groundwater Flow Model to determine potential impacts to environmental features, legal existing users and Minimum Flows and Levels (MFLs). Specific consideration will be given to the newly adopted CFWI rules and impact-related requirements. Preliminary results will be presented in figures, tables and graphics and discussed with City staff prior to Hydrogeologic Impact Analysis report that will be submitted in support of the City’s WUP modification application.
Groundwater Flow Modeling. The Work Plan shall include provisions for the use of a numeric groundwater flow model to better understand groundwater movement in the Study Area, support the placement of groundwater monitoring xxxxx and complete other field activities, and/or evaluate remedial alternatives. OCWD has developed a groundwater flow model of the Study Area (the “OCWD Model”). The Work Plan shall include provisions for submittal to EPA of a report documenting the development and calibration of the OCWD Model. The Work Plan shall include provisions for submittal to EPA of a Groundwater Flow Modeling Plan. The Plan shall provide for revisions to the OCWD model if needed to address EPA comments, and provisions for submittal to EPA of preliminary modeling results and a Groundwater Modeling Report at the completion of the modeling effort. The model shall be calibrated over a wide-range of hydrogeological conditions and have the capability to simulate transient conditions in three dimensions. The model shall be capable of conducting particle tracking simulations to evaluate hydraulic control. The modeling effort shall include a sensitivity analysis. The modeling effort should consider the procedures outlined in EPA’s guidance document “A Systematic Approach for Evaluation of Capture Zones at Pump and Treat Systems, EPA/600/R-08/003, January 2008.”
Groundwater Flow Modeling. OCWD shall conduct groundwater flow modeling in accordance with the approved Work Plan and approved Groundwater Flow Modeling Plan.
