I have a friend looking to buy a house, but the inspection says there is e.coli in the well. They want to run a Chlorinator, but I'm wondering what his options are.

First of all, lots of times e-coli gets found in the water because of a bad sample or someone taking it that doesn't know what they are doing. Realtors, homeowners and others are allowed to take these samples. When I take one, I run the faucet for at least ten minutes, then I spray alcohol all over the faucet including up inside the spout then run it again for a minute or so. Next take the sample carefully being very careful not to touch the bag on the inside.

If a house has been sitting for several weeks or months, the water can get an over abundance of bacteria growing in the pipes. When this water is sampled, the test comes back normally with TNTC. Too numerous to count. In that case, the well should be chlorinated and pumped through all plumbing to kill all the bacteria present. Then resampled. Letting the chlorinated water stay in the pipes for a minimum of 4 hours is recommended.

If the well is a surface water well, chances are it will always have e-coli in the water.

They said the well is only 30' feet deep. What your thoughts on Chlorinators and lights that kill harmful things?

Not sure what 30' would be considered where you are. In Michigan years ago, there were a lot of 30' wells that were perfectly fine.

I never liked chlorinators because the chlorine eats everything in your system eventually. UV lights aren't the cure all either. The water has to be clean that goes through them or the mineral in the water shortens their life. The other thing is the maintenance. Your always babysitting both of them.
