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 <br /> from <br /> data collected from both the ongoing PC - South ATSTM pilot and the operational Egret Marsh Stormwater <br /> Park ATSTM <br /> facility 7 8 , 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/L Water T °C Standing <br /> Crop m <br /> Month 10 : 1 Blend 10 : 1 Blend 10 : 1 Blend <br /> January 0 . 136 0 . 75 19 . 7 50 <br /> February 0 . 112 0 . 72 2044 55 <br /> March 0 . 333 0 . 84 2209 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 <br />10 , with the actual <br /> performance notably higher than the ATSDEM projections . <br /> " Egret Marsh 10 MGD Algal Turf Scrubber® Final Basis of Design Report" July, 2005 .
