    Well water insepection, how disinfect a Well

    I have a 30 foot 2 inch driven point well. It is setup with a packer jet ass. and one of your vertical jet pumps.
    The village I live in is requiring me to get the well water tested for pathogens.
    They are telling me I need to bleach the well, let it stand for 24 hours then run the well for 3 hours. They will they come out and draw a sample of water and test it.
    I am not sure how I can do this because I can only pour bleach down the hole of the outer casing. Would this even work , would this damage the leathers?
    The whole thing is ridiculous because the well is connect to my lawn sprinklers and is not used for anything but that.
    Thanks for your advice.

    These water agencies are getting more and more out of control every day. I have no idea why they want to check for something that you're going to put on your lawn. If in fact you had any sort of pathogens, chemicals or even radiation, you can't do anything about it with a jet in the well. The bleach has nowhere to go. The leathers in unison with the foot valve forbid anything to go down the well unless you pull them both out first.

    What is sad is how little these bureaucrats actually know about well water or the equipment used to extract it.

    What is even more pathetic is that the layer of ground water I am drawing from has been created by a river and creek that run a few hundred feet from my house.
    It is perfectly acceptable for residents to draw non-potable water from the creek and water their lawns.
    I am drawing the same water through the sandy soil using a sand-point, my water must be potable. It is ridiculous.
    What this is really about is the $115 fee they charge, every 5 years for having a garden well in the village.

    So I guess I am going to have to purchase new leathers and pull the whole drop pipe up, so I can shock the well.
    If an "unacceptable" level of pathogens are found in the water sample, they will require another test and charge me an additional $40 fee. So if I am going to do it I may as well go all the way.

    I would let them take the test first. Chances are the water will come back perfectly fine. Just make sure they sterilize the faucet they are taking the sample from with alcohol and make sure it was run for at least minutes prior to testing.

    My water test came back with coliform. They are making me test it again.
    I have been told this is very common for wells in the area I live in.
    I did pull the drop pipe and replaced the leathers and shocked it with a half gallon of pool shock. About a week transpired between the shocking and test.
    The pipe from my pump runs directly into my sprinkler line and it is not checked with a ABV or check-valve. The faucet sits between the pump and the connection to the sprinkler line (see photo). Since it ran for a week prior to the test and the water to the pump is unchecked could the water from the sprinkler line be contaminating the line that has the faucet?
    Each one of the water tests costs $40. So I want to get this done because it is getting expensive. Pulling the packer ain't no picnic either.
    The well is about 5 years old.
    I am looking for some advice.
    The water test must come back free of chlorine.
    Can I drive the point another 10 feet deeper? Or will the sand point because of its age not handle it?
    All of this so I can water my lawn....

    It wouldn't be a bad idea to install a sample tap rite after the Union at the pump. Take the sample there. That would rule out the sprinklers getting into the test somehow.

    Coliform bacteria are present in practically all well water. It's the amount that makes the difference. Fecal Coliform is the bad bacteria that can give you Montezumas revenge among other things. Here when a sample comes back with Coliform that is too numerous to count, the sample flunks. Then the chlorine will kill it off for a better sample. This generally happens from a well sitting for a long time with no usage. It gives the bacteria time to grow into larger numbers. Another way that the sample can flunk is simply the amount of bacteria on ones finger or on the tap they are sampling from. There is enough there to flunk the sample. That's why you never touch the inside of the bag and have to use alcohol on the tap; inside and out. If these guys aren't doing these things, the samples will always flunk.

    What a ruse these Bureaucrats have going.

    The water test did not come back with e-coli or fecal bacteria. Just failed the coliform test threshold. I didn't get the results in the mail. I found out if failed because I called the lab. They just said it failed for coliform.
    As far as the well sitting. The well sits without running from October to May. So that is plenty of time.
    The guy who took the sample took a propane torch to the faucet before taking the sample. That may not have been enough.

    Right, that's what they call "too numerous to count" here. That type of bacteria is harmless, it just needs to be slimmed down. I would run the well for a couple hours full blast before doing anything else. Then if you want to pull the jet again and chlorinate it, it should pass. In my opinion it should pass without chlorinating it, but I can't guarantee it.

    When you say "full blast" what do you mean? With the restricter bolt as far out as it will go with the ball valve to the sprinklers shut?
    When I had the test taken the pump was run the sprinkler for 5+ hours. When he drew the sample the sprinklers were still running. He let open the tap and let it run for a few minutes on to the ground, Closed it, and ran a propane torch all over the surface of the tap, then took the sample
    So water was being pump into the sprinkler line and out the tap.
    Could running the water out of the tap pulled some of the water from the sprinkler line into tap and then into the sample?
    Please excuse my ignorance, I don't have any experience with this stuff.

    No, it's all under pressure heading in one direction, ,so the sprinkler didn't contaminate the sample. Sounds like he's taking the samples correctly, he is just too picky on the results. I don't think your ever going to get this to pass until they lower their standards and from what your telling me, they are just making money. It has nothing to do with bacteria.

    How did us kids ever make it through childhood without the govt looking out for us. I mean eating worms, dirt, mayonnaise that had been out in the sun "heaven forbid". Swimming within an hour of eating "cramps"? Drinking water from the garden hose, or in my case from the well I just repaired before I even hooked it up. Drinking from the flow pipe while I was pumping it off.
