About six years ago, we did a major addition to our house in Florida resulting in needing to add another septic. Neighbor behind us had a well on her property too close to where our second septic was being put. We asked neighbor if she would consider moving her existing well a little further away on her property if we paid for a new pump and drilling of a new well and allow her to select the company to do the work. She obliged. I believe she selected the company her did her initial well. Her lot is probably between 1/4 to 1/3 acre, to give you size of area, and the distance from her old well to where she drilled her new well is probably 50-70 ft. away. We had city waters and assumed most others around did as well, but found out in the middle of the renovation she did not. Anyway, flash forward now. About four months ago (remember the new well was done in 2008), she informed my husband that her water has a rotten egg smell that comes and goes, and all she knows is she never had it with her old well. She didn't specify to my husband if the smell started immediately after she got the new well or exactly when it started. My husband was so taken aback to just be hearing about this years later, so he didn't think to ask if her if she did things like contact the company that did the new well, or verify exactly when the smell started. Personally, I would have to believe she would have called them if it was anytime in the months after getting the new well, but regardless, here we are, hearing about this from an elderly lady who is wishing she never moved her well for the couple behind her doing a renovation, even if her old well could have started having the same problem. Guess that's my reason for this post. Could this have happened in her old pump, too, meaning, could she just out of the blue, started having a rotten egg smell? Additionally, regardless of that answer, what is some advice I can offer to her to help get rid of this smell. I'm trying to be sympathetic. Thanks. For what it's worth, I lived in a house located about three blocks from hers/mine growing up, and we had a well, and it had a little smell to the water (some friends said smelled like rotten eggs). Plus, a house a mile from here that we rented while renovating our house had so much iron in the water, it would turn my hair. Just saying, the water around here has some strong minerals in it, for sure, but apparently her old well water 70 ft away didn't bother her and she wishes for that again!
