INDIAN RIVER COUNTY FLORIDA <br />DEPARTMENT OF UTILITY SERVICES <br />Date: January 28, 2015 <br />To: Joseph A. Baird, County Administrator <br />From: Vincent Burke, P.E., Director of Utility Service4) <br />Prepared By: Arjuna Weragoda, P.E., Capital Projects Manager AP <br />Eric Charest., Environmental Compliance Specialist <br />Subject: Spoonbill Marsh — Update. <br />DESCRIPTIONS AND CONDITIONS: <br />Spoonbill Marsh has successfully been in operation close to five (5) years since its inception in <br />August, 2010. The success is measured through the net environmental benefit associated with the <br />operation of the Spoonbill Marsh wetland treatment system. The net environmental benefit can <br />simply be described as the reduction of nutrients (Total Nitrogen, TN and Total Phosphorus, TP) by <br />the Marsh system when compared to the untreated river water. <br />Using ponds, aquatic plants and even oysters as natural percolation and filtration devices to treat <br />the demineralization concentrate and river water is still considered a cutting-edge practice yet one <br />that has proven to be effective. Apart from achieving its primary goal of water quality, the marsh is <br />home to many migratory birds, fish and other terrestrial and aquatic wildlife, which has created a <br />secondary benefit to the environmental enthusiast. <br />The subject agenda is to update the board with the current operation and performance of the <br />treatment facility known as Spoonbill Marsh. <br />ATTACHMENT(sl: <br />APPROVED FOR AGENDA: <br />ByIndian River Co.
