Well Inspection Failed
The home I have also failed , we bleached the well heavily followed by a heavy flush, the new numbers came back ok but I also added a UV &amp; filter system, the filter is a simple string filter that I change every 6 months. The UV lamp module I have changed 3 times. The UV lamps are kind of spendy so if you can  check on replacement lamps not just the price. In the last 5 years we have not had a positive test and have not had to bleach the well again. The UV system was suggested by my well guy (he is a friend) and I trust his advice is the reason I installed the UV system.
