Pesticides in California’s Central Valley

I am driving along a state road with Becky, a local activist, who is narrating from behind the wheel. “I once stuck around to see them spray and I had to turn the car around and get out of there, the smell was so overpowering.”

We pull over and I hop out to get a close-up look at the orange groves. I am in California’s Central Valley, America’s fruit basket, where agriculture is king.

Becky Quintana is waiting patiently in the car for me as I crouch down to inspect an orange tree. The leathery green leaves were splashed with white pesticide residue, like a Jackson Pollack canvas would be. It is early December, close to the holidays, one would be forgiven for mistaking the white splotches that covered the trees for Christmas flocking. But it turns out it’s like this year round — the chemical flecks a reminder of the high economic stakes involved in delivering an end product that is shiny, bright, and perfectly spherical.

‘There’s a lot riding on it.” Becky explains. “The fruit pickers bring them to the warehouses where the oranges are washed and waxed to look the way you see them in the supermarket. But most of the time,” she nods towards the fields, “they don’t come off the tree looking like that.”

Decades of applied pesticides and fertilizers have delivered high yield, immaculate-looking fruit to many of the supermarkets in the U.S. and to the far corners of the globe, but not without a local cost. Heavy pesticide and fertilizer use in Central Valley orchards that produce household staples such as oranges, peaches, nectarines, grapes, olives, and walnuts has contaminated local community drinking water.

But pesticides and fertilizers are only part of the problem. The primary groundwater contaminant in the region is nitrate, which can also be traced back to Central Valley’s other reigning ruler: Dairy. Interspersed between the acres of golden fruit, behemoth factories house hundreds, sometimes thousands, of cows. This combination of fertilizers, animal factory waste and old, leaky septic systems cause high levels of nitrate that exceed state and federal health standards and can cause death in infants and cancer in adults. The groundwater is also infused with arsenic, DBCP, dangerous levels of chlorine, and bacteria — all of which cause short and long-term illnesses.

Years ago, my good friend Laurel Firestone co-founded an organization called the Community Water Center (CWC) to bring attention to the water contamination in the region and to advocate for change. I finally visited her and learned more about the impacts of CWC’s work.
