Both Hummock and Miacomet Ponds are major public recreational resources on Nantucket, but both experience algae blooms in summer, including cyanobacteria at potentially hazardous levels. Extensive work has evaluated nitrogen loading in conjunction with the MEP, and in-lake phosphorus levels are known to be elevated, but there has been no focused assessment of the sources of phosphorus supporting algae blooms.
