There is an interactive cyanobacteria page on APCC.org that is tracking 35 ponds every two weeks. APCC is using a flourometer to detect toxic cells, and will compare them to the Dept. of Public Health's data using cell counts. Santuit Pond is still testing over 70,000 cells/mL. Solarbees cannot address the underlying problems of phosphorus loading from interior and exterior sources. There is some concern the postings are not timely. Even ponds that are not densely developed like Santuit have suffered from blooms, including Gull Pond in Wellfleet. There are other issues too, such as invasive snail feces in Cliff Pond in Brewster, where an alum treatment occurred unsuccessfully. The HAB Stat and C-PIX devices from WHOI are currently being calibrated,which will be able to detect and identify cell types and toxins in real time.
