c. Demonstrate the efficacy of one MAPS technology known as an Algal Turf <br />Scrubber® (ATSTM) as an effective structural BMP to citrus growers in the <br />Indian River Farms Water Control District and the public. <br />d. Use an ATSTM to treat the variable flows from a water control district, <br />significantly reducing the land space needs for nutrient removal facilities in a <br />basin that is rapidly changing to urban use with escalating land values. <br />e. Assess the use of an ATSTM to reduce seagrass growth -inhibiting optical <br />parameters, including suspended solids, turbidity, and color. <br />f. Identify beneficial uses for the biomass produced within an ATSTM; to include <br />but not be limited to soil additive, animal feed materials, and biogas <br />production. <br />g. Educate the public about the potential for pollutant load reduction to the IRL <br />using ATSTM for stormwater treatment. <br />3. SCOPE OF WORK <br />Task 1 • Analysis of Existing Water Quality and Flow Data <br />The Consultant shall collect and compile existing data related to (i) the rates and <br />scheduling of stormwater flows targeted for treatment by the ATSTM Project and (ii) the <br />water quality in terms of those parameters as identified within the Egret Marsh Project <br />document, as listed below: <br />• pH, <br />• dissolved oxygen, <br />• salinity, <br />• temperature, <br />• Total Kjeldahl Nitrogen, <br />• ammonia, <br />• nitrates and nitrites, <br />• total phosphorus, <br />• ortho-phosphorus, <br />• total organic carbon (TOC), <br />• color, <br />• biochemical oxygen demand (BOD), <br />• total suspended solids, <br />• alkalinity, and <br />• pesticide and heavy metal scans (limited). <br />Based upon this information, the Consultant shall develop a family of parameter values <br />to serve as the basis of design, to be detailed as average monthly conditions, and <br />3 <br />FAPublic Works\KeithM\Stormwater Projects\Egret Marsh Regional Stormwater Park\Work Orders\Hydromentia - Work Order <br />#1.doc <br />
