Abstract:
New regulations regarding the presence of contaminants in bottled water went into effect in California in January 2009. These requirements include testing, reporting, and notification to regulate the presence of heavy metals in bottled natural spring water sold in California. In the study described in this article, six sources of bottled natural spring water were purchased and analyzed for silver, arsenic, barium, beryllium, cadmium, cobalt, chromium, copper, mercury, molybdenum, nickel, lead, antimony, selenium, thallium, vanadium, and zinc. All of these metals except beryllium, mercury, and thallium were detected in at least one of the bottled natural spring water sources. No concentrations were above either federal or California maximum contaminant levels but arsenic concentrations exceeded California public health goals in all six sources. Improving the California notification requirements for bottled water contaminants would result in a process more similar to the notification process for tap water and would result in better-informed consumers.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
