Title 42 › CHAPTER 6A — PUBLIC HEALTH SERVICE › SUBCHAPTER XII — SAFETY OF PUBLIC WATER SYSTEMS › Part B — Public Water Systems › § 300g–6
Bans the use of pipes, pipe fittings, fixtures, solder, or flux that are not lead free after June 19, 1986, when installing or repairing public water systems or any plumbing that supplies water people might drink. An exception allows leaded joints needed to fix cast iron pipes. Items used only for nonpotable uses (like industrial processing, irrigation, or outdoor watering) and certain large fixtures (toilets, fire hydrants, and some valves 2 inches or larger) are not covered. "Lead free" means solder and flux contain no more than 0.2 percent lead, and the parts of pipes and fixtures that touch water average no more than 0.25 percent lead by a weighted calculation based on wetted surface area. Starting 2 years after August 6, 1996, it became illegal to put non‑lead‑free pipes into commerce except for some industrial uses. Businesses that sell plumbing supplies (not manufacturers) may not sell solder or flux that is not lead free. Any non‑lead‑free solder or flux sold must have a clear label saying it is illegal to use for plumbing that provides drinking water. States had to enforce the installation ban and the public‑notice rules by 24 months after June 19, 1986, using plumbing codes or other methods, and the EPA can withhold up to 5 percent of certain federal water program grants if a State fails to enforce. Owners/operators of public water systems must notify people affected when lead in drinking water comes from system materials or corrosive water, explaining likely sources, health risks, ways to reduce lead, steps the system is taking, and whether alternate water is needed. The EPA must help create testing standards, issue rules if needed under set deadlines, and provide public education and targeted outreach to groups at greater risk.
