More about water shows up from time to time. More web addresses below where more can be learned. Some of these are trying to sell us something but they may have useful info. This has to do with water quality in the US – I can’t find much about water in Mexico but would guess if there are problems in the US there are probably problems in Mexico. Lots of tap water in bottles in the US – why would Mexico’s bottled water not be tap water?
Lead Poisoning Higher in Parts of Calif. Than Flint
http://www.msn.com/en-us/news/us/lead-poisoning-higher-in-parts-of-calif-than-flint/ar-BByBful?li=BBnbcA1
Dozens of California communities have experienced recent rates of childhood lead poisoning that surpass those of Flint, Michigan, with one Fresno locale showing rates nearly three times higher, blood testing data obtained by Reuters shows.
In all, Reuters found at least 29 Golden State neighborhoods where children had elevated lead tests at rates at least as high as in Flint.
No level of lead exposure is safe, but children who test that high warrant a public health response, the CDC says.

How safe is bottled water?
http://www.chicagotribune.com/lifestyles/health/sc-bottled-water-health-0127-20160127-story.html
A report by the NRDC about 15 years ago — the latest large-scale study performed — tested more than 1,000 bottles from 103 brands of water by three independent labs. They found that about one-third of the bottles contained significant contamination with levels of chemical or bacterial contaminants exceeding those allowed under a state or industry standard or guideline in at least one test.
