Polar (purified water)
Polar Beverages publishes an annual lab analysis of the purified finished water made at its Worcester, Massachusetts plant. Polar says the water is filtered by reverse osmosis. It is the base water for Polar's seltzers. — as described by the brand

* pH: The lab flagged this pH reading 'HF': it was measured after the method's recommended holding time. Shown as published.
Source kind: official brand report (linked from polarbeverages.com/quality/). Sample received 22 Oct 2025. The pH result (6.2) carries the lab flag 'HF' (analysed outside the recommended holding time). Alkalinity and bicarbonate ND (as CaCO3). Silica not published. The report covers still purified water. Polar's flavoured seltzers are not covered, and 'base water for seltzers' is our wording, not a claim from the report.
