- sterilizer water quality monitoring for reusable medical devices
The examples below offer further information on common testing circumstances.
Drinking Water Compliance Testing
Analytical Services Tasmania (AST) holds NATA accreditation for many of the physical, inorganic and organic chemical characteristics listed in the Australian Drinking Water Guidelines (ADWG). These guidelines are used to confirm the suitability of water quality for human consumption in Australia. Please see the information sheet below for detailed suites of analysis available at AST for assessing ADWG compliance.
We can also give advice as to whether the test results fall within the guidelines and can set up regular delivery of sampling kits to adhere specifically to your scheduling and testing requirements – the right number and types of sample containers when you need them.

Further information about drinking water quality can be found at the following sites:
- The National Health and Medical Research Council (NHMRC) publishes the Australian Drinking Water Guidelines. Download the ADWG pdf document at the bottom of the NHMRC page for detailed information (See chapter 10 Table 10.6 for health and aesthetic values)
- The Tasmanian Public Health Service – Drinking Water Quality page has many useful links and information pertinent to Tasmania including Treated water supplies, Rural water supplies, Commercial Water Carriers, Private Water Suppliers, Water Quality guidelines and reports, and Rainwater tanks.
AST can assist packaged water producers comply with chemical testing requirements.
The Australia and New Zealand Food Standards Code (ANZFSC) and the Tasmanian Food Act apply to packaged water in Tasmania.
Packaged water is currently included in the ANZFSC standard 2.6.2 (Non-alcoholic beverages and brewed soft drinks).
Please contact us for further information and to discuss your testing requirements.
Private Water Suppliers
AST provides chemistry testing services that assist Private Water Suppliers in complying with drinking water quality regulations.
Please see the DHHS Public Health web site for information and requirements for Private Water Suppliers or contact your local council Environmental Health Officer for further information.
The National Water Commission and the NHRMC have developed a community water planner tool to assist managers of remote community water supplies in managing water quality risks.
Tank water is a good alternative drinking water source when mains reticulated supply is not available. AST is able to conduct algal and chemical testing on your rainwater tank water if required. Microbiology tests can be co-oridinated by AST with local accredited microbiology laboratories, please contact us to discuss your testing requirements.
The following sites provide useful information for rainwater tank owners:
Water for Livestock
The Australian Department of Agriculture and Water Resources has information on Australian water resources policy, including information and guidelines for water quality for livestock.
For details of upper limits of contaminants tolerated by various livestock see the Australian and New Zealand guidelines for fresh and marine water quality: Volume 1, chapter 4.
If it is deemed that testing is required, AST can provide the chemistry and algae testing services to help identify water quality issues for livestock.
Wastewater, Tradewaste and Tankered Waste
AST is able to support light and heavy industries and other businesses in meeting their wastewater, trade waste and tankered waste monitoring obligations. These include processing or manufacturing businesses such as dairy processers, breweries and distilleries, car yards, slipways, abattoirs, fruit and vegetable processers, seafood and marine products processers and other light and heavy industries.
Accredited testing services are also available for sediments and sludges for typical EPN or permit requirements.
AST is able to provide regularly scheduled delivered sampling kits and set up long term laboratory testing programs to help meet compliance testing obligations.
Please contact our laboratory staff for your testing requirements.
Water Seepage Identification
In the first instance, contact Taswater regarding any reticulated supply or sewerage concerns and contact your local council regarding any storm water issues.
Chemical testing can be a useful diagnostic aid when trying to discover the source of water seepage. Fluoride presence can indicate the presence of treated mains supply (any tap water, drinking or sewerage), whereas absence of fluoride could indicate groundwater or some other untreated water source. A presence of fluoride and nutrients may indicate sewerage.
AST can conduct these and other tests to assist in the investigation process. Please contact one of our expert scientists to discuss options for identifying any water seepage issues.
AST provides a comprehensive accredited analysis suite to support environmental monitoring obligations, including evaluation of water quality and research studies.
Water sample tests typically requested include, but are not limited to, low level total and dissolved nutrients (Total Nitrogen (TN), Total Kjeldahl Nitrogen (TKN), Total Phosphorus (TP), Nitrate (NO3), Nitrite (NO2), Ammonia (NH3), Dissolved Reactive Phosphorus (DRP)), TSS, colour, turbidity, total and dissolved non-purgable organic carbon (NPOC), silica, total and dissolved metals, chlorophyll a, algae identification and enumeration (fresh or marine), pesticides, herbicides and other residual by-products. AST also offers similar tests for sediments and soils. AST is also accredited for atmospheric dust fallout.
If performing routine work from the same sites, for the same tests, AST can automate a number of processes to simplify each sampling event. For example; the sending of sample bottles to pre-arranged addresses at scheduled times and accepting samples without detailed submission forms, where by prior arrangement we are given the information on sites and tests to be conducted. These regular analysis projects with AST once established can save samplers and project coordinators time and effort on sampling day.
Please contact us if you would like to set up such an arrangement.
Solid Waste Management Classification and Information Bulletin 105
Solid waste disposal to landfill requires chemistry testing for classification. Information about the requirements is available from EPA Tasmania. AST is able to perform the required tests for Information Bulletin 105 classification and the Tasmanian Biosolids Reuse Guidelines, including the following tests:
- Total and dissolved metals
- Toxicity Characteristic Leachate Procedure (TCLP) metals and organics
- Organics (TPH/BTEX, PAHs, PCBs, TBT, phenols, DDT group, Aldrin, Dieldrin, Benzo(a)pyrene)
- General chemistry tests such as pH, conductivity, volatile/fixed solids, etc.
Our accredited in-house TCLP extraction method has been compared to Australian Standard method AS4439.3 and found to give equivalent results and is applicable to waste classification.
Please contact AST to discuss your requirements.
Contaminated Site Assessment and the NEPM
AST holds NATA accreditation for many of the test methods recommended for assessing site contamination. AST can assist with meeting the testing requirements specified in the NEPM for local conditions. Please contact AST if testing against NEPM guidelines is required. The following links to NEPM guidelines and information may be useful when deciding if testing is required and what tests may be necessary.
- The assessment of site contamination NEPM toolbox has many useful links to guidelines and guidance documents
AST gained NATA accreditation for TRH, vTRH and BTEXN at its most recent previous technical audit. This is in addition to the long standing TPH and BTEX accreditation that AST holds for these methods. Please see our TRH newsletter for further details:

Sterilizer water compliance testing for reusable medical devices
AST provides NATA accredited testing services that comply with the requirements of AS/NZ 4187:2014 Reprocessing of reusable medical devices in health service organisation, including endotoxin testing.
Testing against other standards or other analytical suites is also available:
- EN 285 table B1 – water (feedwater) supplied to steam generator
- EN 285 table 10.1 and table E2 Steam purity tests
- section 188.8.131.52 of AS/NZ 4187:2014
Monitoring steriliser water on a regular basis ensures:
- the steriliser water is not too hard that it impairs the activity of detergents or causes deposits
- the steriliser water will not cause scaling or corrosion of items processed
- the steriliser water is not re-contaminating disinfected items with microorganisms or toxins.
