Looking at buying a house that is on Sepctic and a private Well. Got the well inspection back, and failed for Total Coliform (Ecoli and Nitrate Level are fine). The septic is on the other side of the home, and has a ~20 foot elevation difference, so that isn't the major concern in my mind...How concerned would this failed inspection make you? Their plan is to shock chlorinate it and retest after a period of time.
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 & 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.
The failed test would bother me a lot. I live in a rural part of the country and we’ve installed a lot of septic and well systems. None fail.
There’s a reason for the failed test. If the septic system is about to fail, it could be diverting sewer water towards the well. (Water flows in the direction of least resistance.)
Every septic system has to have a designated backup area. Is that area closer or further from the well?
