Check samples, dates, sampling locations, and applicable requirements. Clarity, taste, or TDS cannot replace the required testing.
Documents to prepare
Equipment delivery, maintenance records, and water quality assessment are separate matters. Operators should keep relevant product documents, actual test results, and operating records, and confirm conditions of use against applicable requirements. Report conclusions apply to the specified time and subject; they are not proof of permanent compliance.
Using records for the next step
Keep separate dates for raw-water information, equipment information, sampling, and records. Distinguish observations from conclusions about their causes, and mark missing information for review. Retain the confirmation basis and document versions when changing configurations or maintenance arrangements.
