I don't think you actually read the stories. The sensors did not "detect water". They sensed some anomalies in magnetic field and plasma density which defied any obvious explanation at the time (in 1997). These scientists did some modeling and showed that those signatures can be explained by the presence of a water plume. That is certainly interesting and supports the conclusion that Galileo may have passed through or very near a water plume, however it is very different from saying that "the sensors detected water".
