I just found the Fedex tag on my front door, dated 8-4-06. This is to my shop where we don't ever take any delivery at the front door, in fact it's always locked and Fedex should know that. Just one of many reasons I refuse to use Fedex in my own business.
So, tonite on my way home, I will retrieve the test kit from the idiots at Fedex and post my results.

The foam is just on the surface and is a very fine texture, like beer foam. Yesterday at 6pm, it was still there, but by 10 pm it was completely gone and the water was crystal clear again. It took 2 full days to disipate.
