Is there a guidance document that outlines sampling techniques for testing lead in public drinking water systems?

Answer:

Sampling techniques for testing lead in drinking water are outlined in EPA's approved methods for compliance monitoring of lead in drinking water. In addition, EPA has several guidance documents associated with Lead and Copper Rule water quality and tap monitoring on our website here: https://www.epa.gov/dwreginfo/lead-and-copper-rule-implementation-tools#WQ. This guidance does not contain the sampling protocol revisions that were introduced in the Lead and Copper Rule Revisions nor any potential revisions that may occur under the Lead and Copper Rule Improvements.
