Borehole water mixed with the sewer line
Q: I have a small well in my home called borehole. Recently i've come to know that the water changed it's smell and this is due to maybe the outside line of guter/drain is mixing in the well water although the well is quite deep almost more than 40 feet. What would you advise as per the water? Has it become impure or can it be used for bath and other purposes?
