Just a general question. I have been worrying about N Fowleri infection ever since I read about it. Had consulted a few doctors too. One ENT specialist told me that he too uses underground water, in fact many people I know use underground water that we draw using jet motor pumps or submersible pumps that we store in overhead plastic tanks. So question is dear Doctors how do you treat your water supply if you also use private underground water. Is isn't possible that we put bleaching powder everyday in the overhead water tank. I read on CDC website that whole house UV filter may not work that well. Whole house RO purification system is quite costly. Do we just take the risk as it is very rare infection or bathing, washing face is not that risky. I read on Quora that water has to be forced up like if one snorts or sniffs vigorously or jumps in a pool without holding nose. I really want to overcome this fear and only proper knowledge can help. You being experts can advise.
