November 26, 2019 <br /> To: Rodney Collins, Town Manager <br /> From: Richard Fork, CN R Director <br /> e S,antult Pond Update <br /> c: Wayne Taylor, Assistant Town Manager <br /> Terri Terrie Cook, Administrative Assistant <br /> Advisories remain posted by the Mas,hpee health Department at Santuit Pond <br /> due to the canbactaria (blue-green algae) bloom. The blooms have continued <br /> into December in the past. As you know, the SolarBee water circulators <br /> effectively controlled the blooms until nutrients including phosphorous in runoff <br /> from the watershed from an extreme rein event 7" of rain) duly 7, 2017 caused <br /> the blooms to return. The SolarBees and other in-pond treatments are not <br /> designed to control runoff from the watershed. The blooms returned in 2018 and <br /> 2019. An additional SolarBee circulator was deployed by the SolarBee <br /> Company July 15, 2 9�at no cost to the Town to see if it would help. According <br /> to the AECOM report can Santuit Pond, most ofthe phosphorous fueling the <br /> bloom is coming from the sediments in the pond. <br /> Chuc ie Green convinced the US Army tars of Engineers USCO to conduct <br /> a feasibility study (underway now) for dredging mud out the bottom f the pond t <br /> remove phosphorous. The USCOE, stated that severing the area is a pre- <br /> requisite for the project is dredging to be done. Severing that area is included in <br /> the Mashpee Comprehensive Watershed Nitrogen Management Plan. 1 have <br /> been looking into technologies, for removing algae from the pond to eliminate the <br /> blooms.. 1 look forward to presenting more information at the Board of <br /> Selectmen's meeting. <br />
