Technical Challenges and Solutions to Pharmaceutical Water System Testing during
Validation and Operation
Technical Challenges and Solutions to Pharmaceutical Water System Testing during
Purpose of the Pharmaceutical Water SystemThai Ministry of Public Health Food and Drug Administration:
Pharmaceutical products should be manufactured under the requirements of good manufacturing practices by licensed manufacturers with the object of ensuring that users will receive efficacious, safe and good quality products.
Good Manufacturing Practice (GMP):
The overriding principle which governs the quality of every aspect of making a medicine.
Every action will only be undertaken by following written instructions and documentation.
All facilities and machinery are correct for the purpose and that they, and the environment in which they are situated, is properly cleaned and appropriately treated
Raw materials must be stored and handled correctly and that exactly the right materials must be used at all times.
That people, both production workers and support staff, must dress and behave as required, be properly supervised and above all, be trained correctly.
That Quality Control is undertaken at every stage of the storage, handling, manufacturing and packing cycle.

Key Tests during Source Water Pre-Treatment Step1. Raw Water Source: Total Bioburden Level, Heavy Metals, Organics, Turbidity, pH,
Hardness Ions to ensure that the Pre-Treatment Step will not be overloaded.
2. After Multimedia Filter / Water Softener / Anti-Scaling – Turbidity, Hardness Ions (Calcium, Magnesium), Conductivity, pH, Total Bioburden Level
3. After Biosulfite and Base Addition – pH Level between 8.0 and 8.5 to ensure complete conversion of Carbon Dioxide to Carbonate for removal by First Pass RO
4. After Pre-RO Treatment Filtration ( 5 Micron) – Hardness to ensure no scaling of RO System and Conductivity and Total Bioburden Level
Conductivity Test1. Purpose: To measure residual ions in the PW/WFI Water that would be toxic for
human ingestion or IM/IV injection or that could encourage Microbial growth
Challenges: Exposure to Atmospheric Carbon Dioxide that dissolves in water to form Carbonic Acid that increase Conductivity necessitates In-line or ImmediateConductivity Measurement
Total Organic Carbon (TOC) Test2. Total Organic Carbon: To measure any Microbial Growth in the PW/WFI Water
System – Biofilm and to measure any resulting Carcinogenic Compounds (e.g. Phenols) that would be toxic for human ingestion or IM/IV injection and to detect any potential Endotoxin build-up.
Potential Solutions: Pooling of Test Samples depending on the LOD and LOQ of the test, Alternate-Day or Weekly Testing during 28-Day Testing
Potential Solutions: More frequent Ozone treatment to eliminate TOC with validated reduce testing schedule and plan
pH, Total Bioburden, and Endotoxin Levels3. pH: To measure residual ions in the PW/WFI Water that could encourage Microbial
growth
4. Total Bioburden:To measure Microbial Growth in the PW/WFI Water System that will lead to increase TOC and Endotoxin levels.
5. Endotoxin Level Testing with LAL: To measure toxins resulting from cellular break down during and after Microbial Growth in the PW/WFI Water System that will lead to toxic shock if injected.
5. System Construction Completion, Pre-Commissioning, Commissioning Dossier
6. Installation Qualification (IQ) = After Pre-Commissioning, Vendor Validation Documentation Review, Installation Confirmation with P&ID Yellow-line Markup and System Walkdown
7. Operation Qualification (OQ) = After IQ and Commissioning with PW Water Testing, Critical Operation and Functional Testing with PW Water Testing (Optional for 28-Days)
8. Performance Qualification (PQ) = After OQ, PW Water Testing for 28-Days from All Key Testing Points and User Points for All USP PW/WFI Tests.
