Departmental Item <br />/a/�/ <br />Indian River County, Florida <br />Department of Utility Services <br />Board Memorandum <br />Date: October 1, 2021 <br />To: Jason E. Brown, County Administrator <br />From: Matthew Jordan, Interim Director of Utility Services <br />Prepared By: Terry Southard, Operations Manager <br />Subject: Finished Water Quality Audit Presentation from Kimley-Horn and Associates <br />Background: <br />Indian River County Department of Utility Services (IRCDUS) owns and operates two water treatment <br />plants (WTPs): South County Reverse Osmosis (SCRO), located at 1550 91h Street SW, and North County <br />Reverse Osmosis (NCRO), located at 7751 58th Avenue. Both of these facilities provide potable water to <br />the consolidated distribution system, which includes remote storage and re -pump facilities that provide <br />treated water to customers. <br />Over the years, IRCDUS has worked with various outside engineering firms to conduct water quality <br />reviews. IRCDUS has consistently worked towards optimizing operations while enhancing the quality of <br />finished water provided. Proactive measures have included design studies, construction of improvements, <br />finished water quality reports, corrosion coupon testing studies and evaluations, flushing measures, and <br />most recently, a Finished Water Quality Audit. <br />Analysis: <br />On February 18, 2021, Purchase Order 89687 was issue to Kimley-Horn and Associates (KHA) to evaluate <br />the distribution system water quality. <br />As part of the review, KHA reviewed historical water system quality test results and coordinated with staff <br />to collect available information regarding customer complaints and issues, lead and copper testing, <br />disinfection byproducts (DBP) testing, and bacteriological and coliform testing within the service area. <br />KHA completed the evaluation and provided a Finished Water Quality Audit, which they submitted to staff <br />in September 2021. Below are some key findings within the report's Executive Summary: <br />IRCDUS has been and continues to remain compliant with the provisions of the Safe Drinking <br />Water Act (SDWA), including the Lead and Copper Rule (LCR), a federal law that was promulgated <br />to protect public health through minimizing lead (Pb) and copper (Cu) levels in drinking water. <br />IRCDUS' compliance sampling for Pb is underthe action level (AL), the upcoming trigger level (TL), <br />and the Practical Quantitation Limit (PQL) for Pb. <br />IRCDUS' compliance sampling for Cu is well under the AL for Cu. <br />59 <br />
