Impact/Purpose:
After providing an introduction on lead plumbing sources and variability, this presentation reviews sampling protocols for quantification of lead (Pb) contamination in drinking water. No single universally established sampling protocol for Pb in drinking water exists, and not every protocol is relevant to every sampling intent. It is therefore important to be able to distinguish between sampling protocols, and to understand their purpose. Sampling protocols for lead in water can be broadly categorized based on their intended purpose into three groups: 1) Pb regulatory compliance/corrosion control efficacy, 2) Pb plumbing source determination or Pb type identification, and 3) Pb exposure assessment. Choosing the appropriate protocol is crucial to producing meaningful data and a meaningful response to answer a specific question posed. Understanding differences in protocols is also crucial when attempting to compare Pb results obtained by different water sampling protocols.
