A few days back I noticed a considerable amount of standing water around the casing of our well pump out behind the house. I immediately called our local plumbing company and shut off the switch to the pump. Over the past probably 5 days, we’ve been using as little water as possible and only switching the pump back on to do dishes, shower, ect. I always shut it off promptly afterwards, but I forgot to tonight and it was about 2 hours before I remembered. After I had turned it off, I went out to the well and while it wasn’t terribly wet around it, I noticed there was foam beads that had come from the ground and was around the well pump casing. Probably a good couple hands fulls worth. Any ideas on what this is from?
