air conditioner coil failure/leaking

I had 40 American Standard ac units installed 7-07 in 40 townhomes that i built. These are 2/ 2.5 13 seer units. From the beginning the coils have leaked. Even the replacement coils have leaked. 22 out of 40 so far. When the installer pulled the bad coils the cooper had turned black. They sent the coils off to American Standard and they did testing and came back with a sulfer build up on the coils was what was causing the leaks. They now say it is in the enviroment of the townhome that is causing the sulfer build up thus causing the leaks. Has anyone heard of this before?? These units are less than a year old.
