SANDWICH — The Sandwich Health Department is warning people of a cyanobacteria outbreak in Mashpee-Wakeby Pond.
The town’s Department of Natural Resources determined the community should not use the pond or allow pets to swim or drink, according to a statement from the health department Tuesday.
The department has posted information regarding the outbreak at the entrance to Wakeby-Ryder Conservation Land.
Cyanobacteria is a result of the warm temperatures in the water and nutrient-loading in the pond from septic systems and fertilizers, according to the statement. Cyanobacteria or blue-green algae will appear as a green dense growth on the surface and slightly below the water surface.
