Lab Control refers to the strict protocols and documentation that govern all testing activities to ensure reliability, accuracy, and legal defensibility of the quality checks.

A. Laboratory Setup and Accreditation

• In-House Lab: A dedicated, well-equipped laboratory for frequent, rapid testing of critical parameters (pH, TDS, basic microbiology).
• External Certification: Utilizing NABL-accredited (or equivalent national/international) external laboratories for mandatory periodic testing of highly sensitive parameters like heavy metals and pesticides, providing independent verification.

B. Standard Operating Procedures (SOPs)

• Sampling Protocol: Detailed SOPs for where, when, and how samples are collected (source, in-process CCPs, final product) to ensure they are representative.
• Testing Methods: Use of Standard Methods for Water and Wastewater Analysis (e.g., APHA, ISO) for all tests.
• Equipment Calibration: Establishing a rigid schedule for the calibration and maintenance of all laboratory instruments (pH meters, spectrophotometers, balances) using certified standards to guarantee accurate results.

C. Documentation and Traceability

• Chain of Custody (CoC): Maintaining a documented process that tracks the sample from collection through analysis to disposal, ensuring its integrity and legal traceability.
• Record Keeping: Comprehensive records of all quality checks, including date, time, analyst, instrument used, results, and action taken. This includes:
  • Batch-wise Test Reports: A full report for every production batch.
  • Corrective Action Reports: Documentation of any time a test failed, the cause was investigated, and the corrective measures were implemented.

By maintaining these detailed controls, BlueTurtleWater can consistently guarantee product safety and quality, building strong consumer trust.
