What happens in Greenwich

The following are taken in similar intervals as from Stamford's treatment Plant. There are major differences! The tides are incoming on both samples (Greenwich and Stamford).

Outside Captain's island (Basically in the Sound)
total coliform CFUs/100 mL 20
fecal coliform CFUs/100 mL 2
Escherichia coli CFUs/100 mL 2
enterococcus CFUs/100mL 16
phosphorus as reactive phosphate less than 0.221 mg/L
nitrite nitrogen less than 0.003 mg/L
nitrate nitrogen 0.588 mg/L
pH 8.33
turbidity 1.52 NTU

mid Greenwich harbor
total coliform CFUs/100 mL 44
fecal coliform CFUs/100 mL 4
enterococcus CFUs/100 mL 32
Escherichia coli CFUs/100 mL 4
phosphorus as reactive phosphate less than 0.221 mg/L
nitrite nitrogen less than 0.003 mg/L
nitrate nitrogen 0.647 mg/L
pH 8.22
turbidity 1.36 NTU

Indian Harbor Yacht club
total coliform CFUs/100 mL 500
fecal coliform CFUs/100 mL 90
enterococcus CFUs/100 mL 160
Escherichia coli CFUs/100 mL 70
phosphorus as reactive phosphate 0.224 mg/L
nitrite nitrogen less than 0.003 mg/L
nitrate nitrogen 0.772 mg/L
pH 7.90
turbidity 2.15 NTU

Grass island Boat Ramp (near the treatment plant discharge)
total coliform CFUs/100 mL 670
fecal coliform CFUs/100 mL 120
enterococcus CFUs/100 mL 190
Escherichia coli CFUs/100 mL 80
phosphorus as reactive phosphate 0.471 mg/L
nitrite nitrogen 0.004 mg/L
nitrate nitrogen 0.935 mg/L
pH 7.72
turbidity 2.30 NTU

Note the gradual increase in Nitrogen . Phosphate and turbidity and decrease in pH as the samples approach the treatment plant discharge.

Sewage in the Environment! Bad or Good?

As I appear to get sharper and more on top of things, there are more things to talk about in the environment. The Greenwich sewage spill. Greenwich has a lot of problems with their infrastructure regarding the the sewer lines. They don't have some one like Stamford does in the person of Jennette Brown who is obsessed (in a very positive way) with treating sewage. Their problems (along with the towns upstream) have kept Byram Beach on a very precarious "open" status. But do I think this is necessarily bad, No! Truth is for many years, there was no swimming in the winter because the treatment plant just let the sewage flow out untreated into the Sound. Now I know everyone is going "yuck" right now, but it actually provided for the nutrient base for an incredible fishing hatchery in the sound and while this was going on, there was no hypoxia! The balancing act of nature absorbed all those nutrients and produced, surprise, fish! Now I will admit, according to the theory that I proposed a few posts ago, it also created the ground work for the problems we now have. anaerobic bacteria working full tine to produce the toxic H2S. So in light of my previous post concerning the late rain, there might be an added benefit from this sewer break and fisher people might have a positive surprise this coming spring. Of course I do not recommend releasing untreated sewage into the sound due to the disease issues, but there are ways to deal with the diseases before the stuff whits the fan, so to speak.
