There's no clearer sign that state environmental regulators have failed to protect public health than the warning issued this month to parents living in the shadow of the Exide battery recycling plant in Vernon: Don't let children play in the dirt in your backyard.

Local government authorities should be more aggressive as well. This month, Supervisor
