Bay water quality/safety for swimming

not a scientist but went swimming on 10/31/18 at far end of La Ropa towards Las Gatas and there was lots of plastic under the water at 3 ft depth and green bubbles on the surface with maybe 3 foot of clarity. The reality is the bay is polluted and some effort towards a sewage plant capacity increase or at least storm water separation for the most heavily populated areas is urgently needed . This is an issue that the chamber of commerce folks should jump on if they care to protect tourism.
