No. Distilled water will read 1.000, while even the hardest tap water might read 1.001 or 1.002 or so.
One thing to keep in mind is that you several times mentioned "adjusted for temperature". You do need to adjust for temperature, but even so the readings must be cooled to under 100 degrees before reading and then adjusting for the temperature. If any readings were done above 100 degrees or so, they are pretty inaccurate and therefore worthless.
