Retesting well water

[Rman]

I had a 325 ft drilled well done 2 years ago today. It tested all within allowable parameters
Do or should I have the water retested again?
No plumbing work done regarding well or pump
Water tastes the same but having sometimes gastro gut disturbances (diarrhea)
Should I just shock the well again the installer used 2 gallon Clorox
I'll need to wait when the temperature is above 10 deg to open well ahead
Thanks

A water test every once in a while is a good idea. Even better idea if you notice health problems. Chlorine might be all you need, but we don't know what your dealing with without a test. Some contaminates can be recurring, which needs to be addressed.

https://terrylove.com/forums/index....izing-extra-attention-to-4-inch-casing.65845/ is my sanitizing writeup for deep bottom-feeding wells.

For wells that are not bottom feeding, the treatment could include pellets that can sink to the bottom.
