Our new well is driving us fits. In Minnesota, we are down about 250 ft. just above sandstone, PVC casing, Constant Pressure Pump system, flows max about 25 GPM. Water is absolutely great, except for very strange issue. When we start up flow, if greater than 5 GPM, will run clear for a few minutes, then get silt and turbid for a few minutes, then start running clear, and will run clear indefinitely. As soon as we stop for 5-10 minutes, same thing over. How is silt getting into well when it runs clear. At low flow, silt seem steady, doesn't want to clear.
Well was developed and also driller came back and blew out second time. Water static level is about 75 ft. and pump, 1.25 Hp is at about 140 ft. PVC slit screen about 20 ft.
We hate to abandon this and start over, because water in this area in sandstone has lots of iron at deeper levels.
We don't have a clue why after several weeks, situation is not getting better and about to give up.
Was error made in casing, screen, grouting, etc. or is just well not wanting to develop. Or some strange plume issue.
We are thinking of trying large sediment tank filter backwash system.
