For standard tests, we endeavour 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 8:15am 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. 

Our laboratory is accredited with National Association of Testing Authorities (NATA). To view the scope of our accreditation, please visit the NATA website and locate Toowoomba Regional Council Laboratory Services.
