Water Bubble on Side of Liner

[thadius65]

I have had a protruding bubble of water on the side of my liner in the shallow end. Today, to test for a leak anywhere, I used dye around skimmer, inlet and steps with nothing found. I decided to pull the bead away from track where the bubble was to capture some of the water. I wanted to verify if pool water or ground water. Tesing of pool water was 3800ppm of salt. Tesing of water in the bubble behind the liner was 800ppm. Question - can ground water contain some salt? I am assuming this now means that water is NOT from my pool. I just can't see how the salt PPMs would reduce that much. Thoughts from any of the experts?

Thanks!

Salt content in local water. Hummm. Are you on city water or a well?

Salt is added to pool water. The water behind the pool liner had less salt and assuming it is Ground water. There is no mention of local water.
