Newer Green [Columbia] Hydro Flask:
Tested in August of 2017.
Older Orange Hydro Flask (pre-2013), center sealing dot on bottom:
177,500 ppm lead.
Good job on getting the lead out Hydro Flask!
The lead is in the bottom “sealing dot” on the outside of the product (see center dot in bottom photo on this post) and does not touch the contents of the water bottle. The leaded sealing dot is usually covered with the colored powder coating of the water bottle BUT that coating can wear over time (with normal use) and potentially expose the lead on the bottom.
Newer Hydro Flasks (2017 and newer, based on what I have tested) seem to be consistently lead-free! In 2015/2016 Hydro Flask had offered to replace the older leaded products with a lead-free product, so it might be worth giving them a call to ask for a lead-free replacement if you have an older product!
