New well sitting inactive 2 years now running dirty water

[Tracey]

Last year, we bought a piece of land that already had a well drilled on it. Since the well was drilled it has just been sitting inactive for about two years during the selling/house building process. The well is 125 feet deep with a 60 gallon per minute recovery rate and metal casing. When the plumber hooked up the water to our new house the water was running very muddy. We were told to just let it run straight from the pressure tank outside using a hose. We let it run nonstop for about a week before it started clearing up. Now that we are getting clear water we have a whole new problem. The water gets very muddy immediately after you shut it off. We were told to continue to try and flush out the mud by running it nonstop until it clears and then shut it off for about 10 to 20 minutes so it will get muddy and then repeat. We did this for another two weeks. It continued the same pattern but was not getting any better. So, we contacted the guy who originally dug the well, he came out with his rig and blew it out. We thought that would fix our problem, but it didn’t. Same pattern, the water will clear up until you shut it off for 10 to 20 minutes then instantly gets muddy when you turn it back on. Again, we did this routine for another two weeks without improvement. So the well guy came back out and dumped 3 bags of stone down in the well to work as a filter and try to keep the sediment down. We have been running it for 3 days now since they dumped the stone. It is getting a little better, not as muddy as before, but still is keeping the same pattern. This is so frustrating, we just want to move into our new house! Has anyone ever heard of this happening before or know how to fix it?

They might not have set the casing deep enough or there is a leak where the drive shoe was pressed into the rock. If a video inspection is done that might reveal some clues. I would see if your county or state offers that service.

It sounds like it is the upper part of the water table that is making the dirt. When you shut off the pump, the water level rises, and the next time the pump starts it pulls in the dirt from the upper level. You may want to run it with a timer. That way you could run it for 20 minutes and turn it off for 20 minutes, and let it do that over and over. Sometimes it just takes a while to develop a well. If/when you decide it is not going to clear up, then you may want to think about drilling another well with a fine screen and small gravel pack for a filter.

Thank you for your replies!

Reach4,
The notes on the well document states.

Limestone 75 to 125 feet
Hit Water at 115 feet
6 inch metal casing 95 feet
