I am in the process of compiling asurvey of all well water in Stamford. I have on record about 4,000 of the 5,100 wells that are in North Stamford.
I have a basic fact sheet almost completed and will post. I will also GIS the info to see any patterns.
The basic info so far shows things I have already published, softeners will pollute your own water supply and are the main reason for excess chloride in the water.
There is not much info (14 tests) on Radon, but at this point that looks pretty grim.
Discoloration from Iron and Manganese and acid water are the main issues.
Most wells are very healthy.
That is the summary.
