Is there a guidance document that outlines sampling techniques for testing lead in drinking water?
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, a document entitled Revised Lead and Copper Monitoring and Reporting Guidance for Public Water Systems (EPA816-R-10-004) provides guidance on lead and copper monitoring for public water systems. This guidance document is available at http://water.epa.gov/lawsregs/rulesregs/sdwa/lcr/compliancehelp.cfm.
