Orleans panel reviews cyanobacteria buoy pilot as herring counts hit decade low

ORLEANS — May 27, 2026 — Orleans water quality panel weighs startup cyanobacteria buoy as herring run craters to fewer than 50 fish. The Orleans Marine and Freshwater Quality Committee met Wednesday, May 27, to process $215,000 in newly authorized water quality funding — including an alum treatment at Baker's Pond and a sediment study at Cedar Pond — and to evaluate a proposal by the Orleans Pond Coalition to pilot a continuous-monitoring buoy from Woods Hole startup Subtitle at Pilgrim Lake, at a cost of roughly $1,000 per month for the May-through-November season, compared to the existing $1,500-per-pond-per-season APCC testing program. Committee member Rich Levy reported that volunteer herring counts are on track to total fewer than 50 fish for the 2026 season, less than half of last year's count. Members raised questions about whether the buoy's single-point data would capture shoreline blooms and whether the state's two-week waiting period before reopening a closed beach would limit the device's practical benefit; the committee agreed to invite Subtitle to present at its June 29 meeting. A second startup, Nyad Technologies, pitched a solar-powered phosphorus-filtration buoy at $5,400 plus $4,800 annually for filter replacement, with members flagging the company's plan to resell captured phosphorus to fertilizer manufacturers as inconsistent with Orleans's fertilizer reduction goals.
