Lead Content and Leaching Data for Plumbing Components in LMICs

192 µg/L average lead leaching from brass taps and 34 µg/L from galvanized steel spouts were measured over a 19-day experimental period. Kyle Rezek tested galvanized steel, brass, stainless steel, and PVC plumbing components against NSF 372 and NSF 61 standards. The dataset was last updated on April 17, 2026.

Use Cases

• Compare lead leaching levels based on material type (galvanized steel, brass, stainless steel, PVC)
• Evaluate compliance with NSF 372 (lead content) and NSF 61 (leaching) standards
• Assess health risks from plumbing components in groundwater-supplied systems
• Identify safer alternatives for rural water infrastructure based on experimental data

Strengths

• Provides specific lead leaching concentrations (e.g., 192 µg/L for brass taps) with standard deviations
• Includes results for multiple material types tested against two established NSF standards
• Data is openly licensed under CC-BY-4.0

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset is very small (5.5 KB), indicating limited scope
