"The second episode, which aired last week, highlighted another aspect of the drought. It shows how farmers are using treated oil wastewater to irrigate their crops, despite the fact that nobody has tested the wastewater to see if it's safe.
"There are farmers so desperate for water in one particular irrigation district called Cawelo, they're taking some wastewater to irrigate crops from Chevron. It's being used to grow food for people—citrus crops, grapes, pistachios," Tom Frantz told Deol in the episode.
"You grow an orange—it's 90 percent water when it gets to the consumer," Frantz continued. "Where did that water come from? It's the irrigation water. The irrigation water is toxic, even at very tiny amounts. Is there a tiny amount of toxicity now in the fruit? Nobody is testing that yet. And they're salting up their soil by using this water, which means ultimately they'll have to stop growing everything.""
