Some consider bottled water the safest choice for avoiding drinking-water contaminants like arsenic and lead.
However, recent investigations have found that not all bottled water brands are free of potentially toxic chemicals.
In June, researchers found "high levels" of arsenic in bottled water brands owned by Whole Foods and Keurig Dr. Pepper.
Those findings confirmed earlier research which found levels of arsenic that exceeded the allowable limit set by the FDA.
