I beileve that we should test a water sample for coliform bacteria and other biologicals. The engineer at Lumla ought to be helpful to this end. If it tests fine, then it is drinkable. Also I am interested to know if the water is coming out of the outlet more clear (less suspended particles) than it is going in. If so, we are working just fine.
