Which ESAM Plan component involves identifying the laboratory used for analyses and the required certification?

• A. A Current Map
• B. Identification of Support Laboratory and the Appropriate Certification
• C. Locally Developed Procedures for Drinking Water Surveillance Program
• D. Annual sampling schedule

Answer: (B)

The main concept is ensuring the ESAM Plan specifies which laboratory will perform analyses and what certifications that lab must hold. In environmental analysis, data quality hinges on using a properly credentialed lab, so the plan must clearly identify the support laboratory and document the required certifications (such as accreditation, proficiency testing, and staff qualifications). This guarantees that analyses are performed to accepted standards, results are defensible, and regulatory or programmatic requirements are met.

This focus is distinct from other plan components. A current map relates to locations or infrastructure, not who does the lab work. Locally developed procedures for drinking water surveillance define methods and procedures, not the identity or credentials of the lab. An annual sampling schedule concerns timing of sampling, not laboratory capability or certification.
