A group of scientists at Stanford University has shown that a dangerous contaminant is more common in California's groundwater than anyone previously understood. The contaminant - Chromium 6 - is both naturally occurring and the product of industrial application. Before this study, the scientific community thought that industrial leakage accounted for the largest proportion of Chromium 6 in the groundwater. However, after the gathering of requisite data, scientists learned that natural sources of chromium 6 were much more common and widespread than they thought. These scientists are now researching what causes toxic chromium to arise in nature, and they are trying to find solutions to combat it.
Here's what else you need to know:
What is Chromium 6 exactly?
Chromium is a naturally occuring odorless and tasteless metallic element. It is found naturally in rocks, plants, soil and volcanic dust, and even in the bodies of animals and humans. It's toxic form, Chromium 6, is often produced industrially and used in common for dyes, wood preservation, metal plating, and coatings.
The EPA does not have a "maximum contaminant level" (MCL).However, California has finalized a Public Health Goal of 0.02 parts per billion
Which regions within California is Chromium 6 most likely to be found?
The results revealed Chromium 6 likely occurs naturally in California’s coast and Central Valley. It is also shown that industrial hotspots around Los Angeles and San Fransisco likely produce higher amounts.
How can you be sure to stay away from Chromium 6?
