advice on dirty water

I have an old 6" drilled well on property I am trying to tie into house. It is about 400' deep with a 1 h.p. pump set at 240'. I have ran well a few times in the past six months and water has been clear. A little over a week ago I shocked well with 2 gal. of clorox. Then last Sat, I ran water out but ran pump dry pumping about 20 gal per min for 20 mins and water was dirty before running dry. Since then I have run water 4 times, including today for about ten min at about 10 gal per min (so about 100 gal x 4 times in a week) Water is still not dirty and tastes/smells dirty....I am confused on if I should continue to run, not run, call well man, etc???? any advice is appreciated

I'd use it normally for a time. I think it will be OK. Many times when pumping a well dry will cause water to cascade do picking up debris will the water to become cloudy or muddy.

I'm thinking the bleach was left in the well way too long.

Keep on pumping, but don't let the pump run dry for any length of time as it will damage it.

You should consider some type of pump protection against running the pump dry.

Update: I ran today for about 20 min, about 15 gpm. (I am running at spicket at wellhead.) water is still dirty/ moldy smell.

Gary: I left chlorine in well from Fri till Sun, 2 days. Casing is steel...???

I last did mine 4 years ago and had to run the pump four days and nights non-stop to clear it. I won't do it again unless it fails a coliform test.

steel casing could have a hole rusted into it.. in which case it will never clear, only get worse. might also have something to do with you running your well dry. if dirt/clay/sand/gravel is falling in the well from a hole in the casing, it could be plugging your well causing less production.. the chlorine for 2 days could have been the last nail in the coffin. just something to consider.
