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 7 8, presently under operation. <br /> Table 7 : ATSDEM Water Quality and Algal Turf Input Data <br /> Average <br /> Average <br /> Average TP mglL . ,AverageTN mg/L o Standing <br /> oc <br /> Water T C.

These are reasonable conservative projections, when compared to actual <br /> pilon 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, <br />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 .
