Unhealthy levels of Uranium are seeping into the drinking water of major farming regions in parts of the United States.
While Uranium is a naturally occurring element, it is an unexpected by-product of irrigation and drought which can leak into water supplies.
Sixteen-year-old Giselle Alvarez says her family received a warning on their door that their water could be contaminated.
"The water had high uranium," she says. "[The warning said] it was OK to drink, you didn't have to boil it. It also said that if you drink it over a long period of time you might get cancer."
Long-term exposure to uranium can damage kidneys and raise cancer risks.
