Hello All -
This is my first post here. I've been troubleshooting a well water problem for a week or so, and this forum has been the most helpful resource I've found so I figured I'd post with the hopes of getting answers to my somewhat unique well issue. I've listed the well information at the bottom of the post
My well was dug about 1.5 years ago for a new home. We ran a hose on the well for about a week until it cleared up and then we move in. That was 10 months ago. We haven't had any issued with the well water until 3 weeks ago when we installed a new sprinkler system.
After running the system for a couple of weeks we noticed a lot of silt in the well water. I contacted my well driller and he told me he suspected it was due to increased demand on the well as well as it being spring time here in Montana and the run off stirs up the aquifer. He suggested I run the well at a higher rate than that sprinklers until it cleared. I did that and it took about 7 hours. I shut off the 2 hoses I had on to run the water and within a few minutes it was silty again. Because it's an artesian well, he said we can't surge block the well and that what I'm doing by running the hoses all day is the closest thing to it.
I've now run 2 hoses at roughly 25 gpm for 7+ hours (and then turned them off for a bit to let it get silty again before restarting them) about 6 times, but I can't tell that it's doing any good.
Any advice or insights are appreciated. Even if it's just the suggestion to keep doing what I'm doing! I could use some encouragement at this point as I'm getting pretty discouraged.
Thank you!
Brad
