Lead content limit for solders and flux under SWDA is mandated by which act?

• A. Safe Drinking Water Act
• B. Clean Water Act
• C. TSCA
• D. Federal Insecticide Act

Answer: (A)

This is about which federal law governs the lead content in materials that come into contact with drinking water. The Safe Drinking Water Act, as amended by the Reduction of Lead in Drinking Water Act, sets enforceable limits on how much lead can be present in plumbing materials that touch drinking water, including solders and flux. The goal is to reduce lead exposure from drinking water by restricting lead in wetted surfaces of pipes, fittings, fixtures, and the solders/flux used in plumbing. The other acts address different areas— Clean Water Act covers discharge of pollutants into water bodies, TSCA regulates chemical substances generally, and the Federal Insecticide Act deals with pesticides—so they do not establish these lead-content limits for drinking-water contact materials.
