Ohio Rev. Code Ann. § 6109.10 – Prevention of lead contamination

(A) As used in this section, "lead free" means:
1. (1) When used with respect to solders or flux, solders or flux containing not more than two-tenths of one per cent lead;
2. (2) When used with respect to pipes or pipe fittings, pipes or pipe fittings containing not more than eight per cent lead.
(B) Any pipe, pipe fitting, solder, or flux that is used in the installation or repair of a public water system or of any plumbing in a residential or nonresidential facility providing water for human consumption which is connected to a public water system shall be lead free. This division does not apply to leaded joints necessary for the repair of cast iron pipes.
(C) Each public water system shall identify and provide notice to persons that may be affected by lead contamination of their drinking water. The notice shall be in such form and manner as may be reasonably required by the director of environmental protection, but shall provide a clear and readily understandable explanation of all of the following:
1. (1) Potential sources of lead in the drinking water;
2. (2) Potential adverse health effects;
3. (3) Reasonably available methods of mitigating known or potential lead content in drinking water;
4. (4) Any steps the public water system is taking to mitigate lead content in drinking water;
5. (5) The necessity, if any, of seeking alternative water supplies. The notice shall be provided notwithstanding the absence of a violation of any drinking water standard.
