Under the Safe Drinking Water Act, what is the maximum lead content allowed in pipes and pipe fittings?

• A. 0.2%
• B. 8.0%
• C. 1.0%
• D. 5.0%

Answer: (B)

The question tests knowledge of the lead content limits that were set for plumbing materials under the Safe Drinking Water Act. Historically, the SDWA allowed up to eight percent lead by weight in pipes and pipe fittings. This was the regulatory limit used before later amendments tightened the requirements. The other percentages reference different materials or later rules (for example, solder and flux have much lower lead limits), while the current standards have since reduced allowable lead in pipes and fittings to a much smaller percentage.
