Brown, County Administrator <br />From: Vincent Burke, PE, Director of Utility Services <br />Prepared By: Arjuna Weragoda, PE, Capital Projects Manager <br />Subject: Groundwater Modeling and Impact Evaluations with CDM Smith <br />Descriptions and Conditions: <br />Indian River County Department of Utility Services (IRCDUS) owns and operates two (2) regional potable <br />watertreatment plants (WTP). The South County WTP withdraws groundwaterfrom seven existing Upper <br />Floridan Aquifer (UFA) production wells, while the North County WTP relies on groundwater from nine <br />existing UFA production wells. The St. Johns River Water Management District (SJRWMD) requires that <br />proposed groundwater withdrawals be evaluated against the following water resources evaluation <br />criteria: <br />• No interference with other existing legal users; <br />• Cannot induce saline water intrusion; <br />• Cannot cause or contribute to pollution of the water resources; <br />• Cannot adversely affect existing offsite land uses by more than 10 percent (measured in both <br />quantity and quality of water degradation); <br />• Cannot produce environmental impacts (e.g., harm to wetlands); and <br />• No lowering of Minimum Flows and Levels (MFLs) for designated water bodies. <br />Analysis: <br />Staff requested CDM Smith Inc. (CDM) prepare a proposal to update the groundwater modeling. The work <br />order will be provided in accordance with the Agreement for Professional Services Contract No. 2018008 <br />dated April 17, 2018.
