Chlorinating well

My well cap is in two parts, with a pipe coming up in the middle and then another one with the electrical wiring, there is an electrical box above but it is very close to the cap, making it difficult to even try to remove cap. There is a small plastic screw in the well cap, it is very small is this where Iam trying to add bleach to?

 

The well cap is two parts, there is a pipe coming up between the well cap that also has a screwed in cap. Instruction given to chlorinate state to remove well cap, and in the pictures this well cap is one unit and there is not another pipe coming up through it like ours. Also all the wiring is secured in another pipe, and the box containing the wiring is like an inch and half above the screws to remove the well cap, so it is going to be difficult just to do this. So if I do get this cap off, the pipe coming up the middle has water in it.Am I pouring the bleach into the larger pipe of the two, and there is no way to pour into the pipe up the middle due to the water level in it.

 

You may not even have to take off the well cap. Some have an extra plug in a hole, but you have to use a funnel.

Your object is not to get water into the pipes, but into the well casing. You want to sterilize the initial flow of water into your tank so that you do not contaminate your tank with bacteria.

So, you have a 4 inch well casing with two smaller pipes running through the well cap and into the well casing. You want the chlorine in the well casing, not in one of the smaller pipes.

 

Pardon my ignorance, but why would you do this ? what tank are you referring to, to not contaminate with bacteria ?

 

I did not know that wells had to be checked, we moved into a new mobilehome with a well, it passed its water test at this time but no one suggested having it tested or to do chlorination on a monthly basis. We are now in process of selling, water test came back positive, so we were informed to chlorinate the well.

 

Chlorination of a NEW well is recommended so as not to put bacterial contaminated water into your new pressure tank.

I have never, and never recommended, monthly chlorination. If a well is properly located and at sufficient depth there should be no bacterial contamination. However, it does happen. That is the reason why wells must be located a minimum distance from things like landfills, septic tanks, etc...

Once a well is installed and initially treated a water sample is taken. One of the tests is for coliforms. Those are deadly in sufficient quantities. If a well has coliforms in certain amounts CONSTANT treatment with chlorine may be recommended.

But, I have never heard of chlorinating a well "just because.."

 

There are coliform bacterial that exist naturally in the soil and then there are fecal coliform such as E coli which will cause you problems. The septic is at one corner of our property and the well is at the diagonal corner at the size of property is .75 on an acre. We are back in woods and there is major underwater flow off from a nearby lake. We werre told by our county that due to the area we are living that monthly or permanent chlorination may have to be done.

 

If that is the case have you considered an injection system that meters chlorine into your system as the pump runs? It would be the best thing, I think.

 

That will mostly be something to be done or at the water softener, we just had not had any issues with the water, and probably would not known if it had not been requested by buyer to have water test done.

 

Well is chlorination was done, now how long before chlorine clears?
