How long have I studied Stamford water quality at the beaches? 30 years? May be, but I really got down and dirty with it 20 years ago. This is the run off from all the rain cleaning urban streets and storm systems and hopefully providing food for creatures to eat because out there in the Sound a mile out there is nothing!
The unsettled weather, the 3 inch rain and the other thunder storms all around us has cause the water to have a lot of unusual bacteria organisms, none over limit to allow me to close them, but I would tell you to be careful going into the water. Wash off after.
We have not seen that mystical white Styrofoam type stuff, "Sewage grease" that I believed would be there from the 3 inch rain, but the weather has been very unsettled and may have broken it all apart in the near waters.
The next four or five days promise to be nice weather and that maybe enough to settle every thing down.
From the info I get from beach net, the indicator bacteria (and a pathogen in its own right) will come out of wet sand during this unsettled weather. it has not been numbers I worry greatly about and certainly not in numbers that would allow me to shut down bathing on a Fourth of July weekend, but caution is urged.
