AB1953 proposes to reduce lead content in all plumbing pipe, fittings and fixtures to 0.25%, down from current standards of 8% (for pipe and fittings) and 4% (for plumbing fittings and fixtures). How wrongheaded is this effort? Let us count the ways.
PMI says the decrease reflects the plumbing industry's efforts to reduce children's exposure to lead. I disagree with their interpretation. It's unlikely that plumbing products ever contributed measurable amounts of lead to tiny bloodstreams. The decline more likely stems from cleaner auto emissions and a diminishing stock of old housing with lead-based paint.
