In 2016, more than 190 million pounds of pesticides were applied to farm fields in California. And while the state has a system in place to protect farmworkers, children, and people living in agricultural communities—while keeping these chemicals out of the air and waterways—a new report authored by a team at University of California, Los Angeles (UCLA) argues that this system isn’t working as intended.

“Based on what we saw, I don’t think there’s a lack of interest in doing [evaluations],” says study co-author Timothy Malloy, a law professor at UCLA. Rather, he says, there is a lack of accountability.
