BARNSTABLE (CBS) Marstons Mills residents are upset toxic algae is invading their ponds again this summer.

Delia and her husband bought their home because it sits on Long Pond. Its now closed to swimming because of cyanobacteria.

Its kind of sad because there are a lot of young couples in the neighborhood who bring their children down here to play in the water because its easier than taking them to the ocean obviously. Its safer, said Delia.

Long Pond is one of several closed in the town of Barnstable. Others are on the warning list.

So were monitoring ponds with permanent beaches and ones that are in trouble for Cyanobacteria, Town of Barnstables Coastal Health Resource Coordinator Karen Malkus-Benjamin said.

Cyanobacteria blooms are also called blue-green algae. They can produce harmful toxins and cause serious illness to humans and pets.

A regular person, if they were exposed to maybe a small amount, might feel nauseous or might be dizzy. It could vary, Malkus-Benjamin said.

Two ocean beaches in Barnstable are also closed to swimmers because of another type of bacteria, possibly caused by wastewater. Veterans Beach and Ropes Beach failed sample tests.

Its really disappointing because its a very picturesque area, and, you know, from time to time, youd like to maybe just put your feet in here, said Nancy Pelland, of Barnstable.
