Educational guidance on registers and logs — what each records, who maintains it, what it typically contains and how long it is generally kept. Informational only — template examples, not official documents or legal advice; a register documents activity, it does not by itself prove compliance, and employers remain responsible.
What a water quality log is
A water quality log is a record of the checks and tests carried out on water at a site — temperature, sampling, readings or laboratory results — so the organisation can track quality against the standards or targets that apply.
This page is an educational overview with a simplified example. It is not an official template, not jurisdiction-specific and not legal advice — what must be tested, how often and against what standard varies by country and water use.
Purpose
- Record water checks, sampling and test results over time.
- Track quality against the relevant standards or targets.
- Flag results that need action or re-testing.
- Support hygiene, environmental and maintenance regimes.
Who maintains it
- A facilities, environmental or responsible person keeps it current.
- Sampling and testing may be in-house or by a competent contractor.
- Results are reviewed against the applicable standards or targets.
- The employer decides the regime and who is responsible.
When it is used
- When checks, samples or tests are taken on the agreed schedule.
- When a result is out of range and needs re-testing or action.
- During hygiene, environmental or maintenance reviews.
- After works that could affect the water system.
Typical fields
- Date, sample point and the parameter checked.
- Result or reading and the method used.
- The standard or target it is compared against.
- Whether it is within range and any action taken.
- Who carried out the check and sign-off.
- Example columns only — adapt to your water uses and the applicable law.
Common mistakes
- Recording results but not comparing them to the right standard.
- Skipping samples or sampling from the wrong point.
- Not acting on or re-testing an out-of-range result.
- Mixing different water uses in one log without distinction.
Document workflow
A water quality log runs with the hygiene and environmental chain: sampling is planned, results are recorded here, and out-of-range results feed corrective action and, for water systems, the legionella monitoring log. Discharges link to the effluent records completed afterwards.
See the related documents below for what is commonly used with and completed after a water quality entry.
Retention (high level)
Water quality records are generally kept for a period set by the applicable law and the employer’s obligations, long enough to show trends and support any investigation. This page does not state a required period — confirm with the applicable law and the official authority.
Completing and sharing as a PDF
Results are often held in a system and exported to PDF for reviews and audits. Exporting to PDF supports the record; it does not make the results official or prove compliance.
Employer checklist
- Sample from the right points on the agreed schedule.
- Compare results against the correct standard or target.
- Act on and re-test out-of-range results.
- Keep results linked to maintenance and any treatment.
Worker notes
- Follow the sampling procedure exactly so results are reliable.
- Report taste, smell or appearance concerns about water.
- Do not alter a water system without the responsible person’s authority.
Country considerations
Water quality standards, testing frequencies and discharge rules vary by country and water use, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not legal advice.
Confirm current requirements with the official authority for your country and a qualified professional.
Who is responsible
The employer is responsible for the water quality it is accountable for, monitoring it and for compliance. This page is an educational overview with a template example; it does not make a workplace compliant and does not transfer responsibility.
