Water Quality input data <br /> for an average month,taken from the historical data base is noted in Table 7. The algal turf information is interpolated from <br /> data collected from both the ongoing PC-South ATSTM pilot and the operational Egret Marsh Stormwater Park ATSTM <br /> facility'g,presently under operation. <br /> Table 7: ATSDEM Water Quality and Algal Turf Input Data <br /> Average Average <br /> Average TP mg/L Average TN mg/LWater T°C Standing2 <br /> Cropm <br /> Month 10:1 Blend 10:1 Blend 10:1 Blend <br /> January 0.136 0.75 19.7 50 <br /> February0.112 0.72 20.4 55 <br /> March 0.333 0.84 22.9 70 <br /> Aril 0.171 1.06 24.4 90 <br /> May 0.326 1.37 27.4 100 <br /> June 0.267 1.63 28.1 110 <br /> July 0.148 1.14 28.9 110 <br /> August 0.325 1.54 28.8 100 <br /> September 0.267 1.02 27.8 90 <br /> October 0.227 1.10 25.8 70 <br /> November 0.167 1.12 23.7 60 <br /> December 0.172 0.72 19.5 50 <br /> Alkalinity 228 mg/L as CaCO3 <br /> pH=7.81 <br /> Tissue P=0.60% <br /> Tissue N=2.40% <br /> Initial Standing Crop 10 m2 <br /> The ATSDEM projections are presented in Table 8.These are reasonable conservative projections,when compared to actual <br /> pilot performance from January through April 2011, as shown in Table 9. These projections are conservative,but congruent <br /> with the data collected to date associated with the ATSTM PC-South pilot study, as shown in Table 10, with the actual <br /> performance notably higher than the ATSDEM projections. <br /> '"Egret Match 10 MGD Algal Turf Scrubber® Final Basis of Design Report"July,2005.
