Woman testing water

Toowoomba Region's Mt Kynoch Water Treatment plant houses a comprehensive water analysis facility. Testing is conducted on a fee-for-service basis. More information on fees and examples of available tests and requirements are detailed below. 

What days can I drop off samples?

Chemistry testing

  • We generally accept chemistry samples from 8am to 2.30pm Monday to Friday but certain tests are set up on particular days of the week and samples may have limited holding times. It's best to discuss testing requirements with the laboratory prior to the collection and submission of samples. An example of this is Biochemical Oxygen Demand testing, which is only available on Wednesdays to Fridays.

Microbiological samples

  • Outside of the above exception, we only accept microbiological samples from 8am to 2.30pm Monday to Thursday. These must be provided in a special sterilised container which we can send to you free of charge. Just contact us on 07 4688 6270 to arrange.

Further information

Testing is conducted on a fee-for-service basis. To obtain pricing call us on 07 4688 6270 or download the register of fees and charges here (Pages 8-9 contain the relevant information).

We accept card, contactless and cheque payments only, we do not accept cash. We apologise for any inconvenience.

If you are using Laboratory Services multiple times a year and would like to open an account, please complete a Credit Application form online or by completing the hardcopy Credit application form


For standard tests, we endeavor to achieve a 10 day turnaround. This time can be extended due to increased workloads or circumstances beyond our control. Receiving your report may take longer if you don’t have access to email or fax, as postage can add to delays. If your results have not been received within the 10 day period, feel free to call us on 07 4688 6270 for follow up. It is helpful if you can provide your batch number if known. 


We test against the Australian Drinking Water Guidelines issued by the National Health and Medical Research Council. If a result does not conform to the guidelines, this will be advised at the end of the report. We're happy to accept any enquiries you may have regarding the results and we can be contacted during office hours 8am to 4pm Monday to Friday. 

If you wish to improve or control your water quality, we recommend calling one of the many water treatment specialists in the White/Yellow Pages.

We don't conduct health testing in our laboratory. Please refer to the NHMRC guidelines (National Health & Medical Research Council) for information. The laboratory is a National Association of Testing Authorities (NATA) accredited provider and tests are performed in accordance with NHMRC guidelines. Our Accreditation No is 12009 should you wish to view the scope of accreditation on the NATA website.
