Received 23 June 2014 The main nutrient problem is phosphorus, which causes the highly oligotrophic sawgrass (Cladium Received in revised form 23 September 2014 jamaicense) communities in the northern Everglades to become eutrophic Typha latifolia/T. domingensis Accepted 3 October 2014 communities. Current government directives require that the total phosphorus concentration of storm Available online xxx water drainage into the Everglades be limited to approximately 10 ppb (mg-P/L). Over 23,00 0 ha treatment wetlands, referred to locally as stormwater treatment areas (STAs), have been created from Keywords: farmland to treat the stormwater. They are generally effective in removing 6 0–80% of the total Phosphorus Florida Everglades phosphorus; however, the 10 ppb goal has rarely been achieved. A three-year experiment, involving Treatment wetlands mesocosms planted with Everglades-native wetland plants was conducted in the Florida Everglades from Stormwater treatment March 2010 to March 2013. Eighteen flow-through mesocosms (6 m x 1 m x 1 m with 40-cm water Cladium jamaicense depth) received about 2.6 cm/day inflow. The eighteen mesocosms were randomly assigned with six Nymphaea odorata different plant communities with three replicates of each treatment, consisting of sawgrass (C. Typha domingensis jamaicense); waterlily (Nymphaea odorata); cattail (Typha domingensis); submerged aquatic vegetation Najas guadalupensis (SAV) including Najas guadalupensis, and Chara sp. and a Nymphaea–Eleocharis sp. mixed community; and soil without vegetation as a control. Total phosphorus (TP) in the inflow water was 25 ± 1 mg-P/L (n = 55) over the 3 years. Through 2012 the average outflow of all of the treatments was 34 ± 1 mg-P/L, a 51% decrease from the average outflow of 69 ± 6 mg-P/L for 2011. Outflows began to be routinely lower than the inflow in the 3rd year of the study. The average total phosphorus concentration decreased overall to 19 ± 1 (n = 5) at the end of the study in 2 013 suggesting that the suspected phosphorus reflux from the Lake Erie Algal Blooms “Nutrient impairment continues to plague Lake Erie, impacting an $11.5 billion tourism industry” Ohio Lake Erie Phosphorus Task Force (Nov 2013) Satellite Image from Sept 3, 2011 of Western Lake Erie (Michalak et al. 2013) PNAS SANDUSKY, Ohio – “A green slime is blooming once again around Lake Erie and anglers, boaters and tourism officials are hoping it won't toss a toxic monkey wrench into everyone's fun on the water.” D'Arcy Egan, The Plain Dealer, August 24, 2013 Lake Erie Thursday, August 21, 2014 Mayor says water crisis is similar to 9/11 Both were wake-up calls, led to second-guessing BY TOM TROY, BLADE POLITICS WRITER Mayor D. Michael Collins said on Monday that the water emergency that crippled Toledo’s water supply Aug. 2 was like the terrorist attack suffered by the United States on Sept. 11, 2001 — a wake-up call to community action. And Toledo City Council’s utilities committee on Monday delved into the Aug. 2-4 crisis that made Toledo a national byword for the health threat posed by blooming algae. Mr. Collins said in an interview with The Blade’s editorial board and a Blade reporter that just as 9/11 created a change in Americans’ attitude toward terrorism preparedness, so the great algae bloom of 2014 should not be ignored.
