Microbiological and Chemical Testing
- Is water tested for total coliform and E. coli at a defined frequency? *
- Are results reviewed against potability criteria (e.g., absence of coliform per 100 mL)? *
- Is a corrective action procedure in place for out-of-specification water results? *
- Date of last water test
Non-Potable Water Control
- Is non-potable water (e.g., for fire control or refrigeration condensers) in separate lines that do not connect to or backflow into potable systems? *
- Are non-potable water lines clearly identified and marked? *
- Is reused or recirculated water (e.g., flume, cooling water) treated and monitored to maintain safety?
Plumbing and Backflow
- Is the plumbing designed to prevent backflow and cross-connection between potable and non-potable systems? *
