Which ESAM Plan component includes locally developed procedures for the Drinking Water Surveillance Program?

• A. QA/QC Plan
• B. Current Map
• C. Annual sampling schedule
• D. Locally Developed Procedures for Drinking Water Surveillance Program

Answer: (D)

The part of the ESAM Plan that contains the locally tailored procedures for implementing the Drinking Water Surveillance Program is the Locally Developed Procedures for Drinking Water Surveillance Program. This component is explicitly about capturing site-specific methods, protocols, and workflows that reflect local conditions, responsibilities, and practices used in surveillance. The other components serve different roles: a QA/QC Plan covers quality assurance and quality control processes, a Current Map provides geographic context, and an Annual sampling schedule specifies when samples are collected. None of these describe the actual locally developed procedures for conducting the Drinking Water Surveillance Program, so the locally developed procedures component is the correct choice.
