Help, I'm desperate here.
My 50' well has a lot of very small, fine (1mm) roots in it that are clogging the submersible pump. The pump hangs in a limestone "water-chamber" at the bottom of the well shaft. I don't know how big the chamber is. The driller said he "broke into a chamber filled with water" when the well was drilled 40 years ago. This is the first time we've had this problem.
Does anyone know of a drinking water safe herbicide that can be put into the well to kill the roots? A roto-rooter type probably won't work because the roots/pump are in a chamber, not the shaft.
Any suggestions anyone? I'm desperate.
Thanks
