I’m talking about none of the surfaces the water touches are food grade and all surfaces in contact with rainwater are made with heavy metals that will accumulate in soil. The plants uptake these metals. These metals are especially toxic to pregnant women, children, but toxic to everyone. Can cause kidney, liver, and brain damage.
Are you referring to asphalt shingle breakdown? I'm curious about that.
