Upwards of 75% to 85% of bottled water is tap water.
"So upwards of 75 to 85% of bottled water is tap water. So people don't realize that what companies are actually doing is just filling up from their own tap water." (said at 0:13:47)
No published record matching the claim that upwards of 75% to 85% of bottled water is tap water was located; this does not prove the claim false. Published assessments and regulatory overviews generally estimate that municipal supply accounts for approximately 25% to 50% of bottled water (often treated and labeled as purified water), with the remainder sourced from natural springs, artesian wells, and mineral aquifers, rather than 75% to 85%.
Regulatory data from the FDA and environmental groups report that roughly 25% (with some advocacy estimates reaching up to 64%) of bottled water comes from municipal tap water sources. Conversely, the FDA estimates that approximately 75% of bottled water sold in the U.S. comes from natural underground sources such as springs and wells.
