A small commercial POE (point of entry) reverse osmosis (RO) equipment
was tested for removing simultaneously water radioactivity and salini
ty from a bedrock water in a private household. The functioning of thi
s equipment was monitored over an eight month period. The RO equipment
was able to remove most of the elements almost completely. The reduct
ion of main water constituents was above 94%, except for gaseous radon
.
