Lead, copper and microplastics come from ageing pipes in your street and home — only an on-site test shows what's at your tap.

How we measure your water

Our method, sources & what the official reports leave out

Every figure in your report starts from the public record for your specific supply zone — then we explain what those official numbers don't capture once the water leaves the plant.

1

Matching your postcode to a treatment plant

South East Queensland runs on a single connected bulk-water grid operated by Seqwater. We map your postcode to the council water network that serves it, then to the treatment plant (or plants) that primarily supplies that zone — for example Mount Crosby East Bank for inner Brisbane, North Pine for Moreton Bay, or Molendinar for the Gold Coast.

2

Pulling the plant's published results

For each plant we use the water-quality figures published by the bulk supplier and your local water retailer — disinfection levels (chlorine / chloramine), disinfection by-products such as trihalomethanes, fluoride, hardness and other routinely-monitored parameters — reported as rolling 12-month system averages.

Adding what the official reports don't cover

A plant's report describes the water as it leaves the plant — not what comes out of your tap. Between the plant and your glass, the street mains and your own home's plumbing change the water. These are the substances that don't appear in any council report, and the only way to know your real levels is an on-site test.

Not in your council's water report

Lead

Not present in treated water leaving the plant, so it isn't in the supply figures. It enters inside the property — older brass fittings, soldered joints and some imported tapware can leach lead, and amounts from trace to well above the guideline are commonly found at the tap, especially on first-draw morning water.

Copper

Also a plumbing-side contaminant, not a plant one. Copper pipe is throughout most homes; where water sits in the pipes (overnight, or in homes with newer copper) it dissolves measurable copper, ranging from small to large amounts depending on the property's pipework, water age and acidity.

Microplastics

Australian treatment plants are not legally required to test for microplastics, so they appear in no official water report — yet they are now frequently detected in drinking water worldwide, shed from mains, tanks and household plastics. Because no one is required to measure them, your supply figures simply can't tell you what's there.

In short: the supply figures are accurate for the water the plant produces, and the plumbing-side substances above are well-documented industry-wide — but neither tells you what is in your glass. A free on-site test is the only way to confirm it.
