Water Quality Data Reference

Identifies drinking-water and effluent quality monitoring records: laboratory or field results with measured parameters and units, and sample/site records. Water quality wording alone is discovery-only.

Confidence

Confidence justification

Medium confidence: topic wording is discovery-only; enforcement requires numeric results with units or sample record fields, and 85 needs both plus compliance context.

Jurisdictions

au

Regulations

Water Supply (Safety and Reliability) Act 2008 (Qld)

Frameworks

ISO 27001

Data categories

Should match

• Drinking water quality monitoring results - Mount Carrow water supply scheme Sample ID: MC-RES-0412 Sampling point: Reservoir outlet R2 Date sampled: 14/09/2026 Turbidity: 0.4 NTU Free chlorine: 0.9 mg/L E. coli: <1 MPN/100mL Manganese: 0.12 mg/L - exceedance of the aesthetic guideline value, reported under the DWQMP. — High tier (85) - sample record fields, measured parameters with units and exceedance/scheme context
• Water quality results for Lakeside intake: turbidity 1.8 NTU, fluoride 0.8 mg/L. — Medium tier (75) - measured values with units only
• Water sample register - Site code: WTP-07, collected by field officer on the Tuesday run. — Medium tier (75) - labelled sample record without results
• Please send the water quality summary to the operations team before Friday. — Discovery tier (65) - topic phrase only

Should not match

• No water quality phrase matched by the Purview regex — Unrelated text
• No water quality phrase present — Unrelated text
• Guidance note: the Australian Drinking Water Guidelines say turbidity should be kept low; organisations should test chlorine residual daily. — Guidance naming parameters without results must stay below 75
• Water quality sampling template Sample ID: ______ Sampling point: ______ Turbidity (NTU): ____ Free chlorine (mg/L): ____ — Blank template
• Media release: the council says water quality is safe after last week's storms and the boil water notice has been lifted. — News framing

Known false positives

• Public drinking water guidelines, council water quality web pages and news cite parameters and thresholds. Mitigation: Topic wording is discovery-only; enforcement needs measured values with units or sample record fields, and guidance, template and news framing are excluded.
