Morphology
The literal meanings of 'something' + 'in' + 'water' make it plausible for a learner to infer an environmental cause (i.e., that the water contains something causing effects), so a basic causal reading is accessible. However, the phrase is a conventionalized, metaphorical way to explain unexplained group behaviour and carries an idiomatic nuance beyond the literal constituents, so its full pragmatic meaning may not be fully predictable to a B1 learner without exposure.
Etymology
Something in the water comes from the image of a town where the local water had a change that made many people act alike, for example get sick or suddenly feel more energetic. So, it means there is a 'mysterious cause' or 'unknown factor' making a group behave the same.
