What we do

Order a kit, collect your sample, and send it back. Your water is analysed by a NATA-accredited laboratory and you receive a full results report within 5–7 business days from when samples received by laboratory. No consultant, no site visit, no minimum order.

Bore Water

Groundwater from bores and wells used for irrigation, livestock, or drinking. No disinfection or regulatory monitoring applies — quality is determined by aquifer geology and local land use history.

Dam Water

On-farm dams and storage ponds used for irrigation or livestock watering. Quality varies seasonally — concentration of salts, nutrients, and bacteria increases as water levels fall.

Creek & River

Surface water drawn directly from creeks, rivers, or natural watercourses. Chemistry and microbiological quality vary with rainfall events, upstream land use, and seasonal flow.

Irrigation Channels

Reticulated irrigation supply and on-farm channel networks. Water quality at the delivery point can differ significantly from the supply source — salinity, iron, and sediment load accumulate in transit.

Horse & Livestock Water

Horses are sensitive to water palatability — elevated iron, salinity, or sulfur will reduce voluntary intake before clinical signs appear. Bore and dam sources used for horses warrant the same scrutiny as human drinking water sources.

Stock Troughs

Trough water quality can differ from the source — biofilm, sediment, algal growth, and sun exposure affect microbiological and chemical quality. Collect from the trough if trough-point quality is the concern.

Rainwater Tanks

On-farm rainwater collection used for drinking, spray mixing, or supplementary irrigation. Roof material, guttering condition, and tank age all affect lead, copper, and microbiological quality.

Multiple Sources

Comparing bore, dam, and rainwater sources across the same property in a single submission. The property audit kits cover three or five sources; the 5-Point Irrigation Audit covers any combination of five irrigation sources.

What are you testing for?

Each kit is designed around a specific question. Find yours below, then scroll to the comparison table to see exactly what's included.

01

Will this water damage my crops, block my emitters, or salt my soil?

Salinity, SAR, iron, manganese, and boron — the parameters that determine whether bore or dam water is suitable for crops, orchards, pasture, and drip irrigation systems. Relevant for any property where the irrigation water source has not previously been tested.

Recommended: Irrigation Suitability Screen · 5-Point Irrigation Audit

02

Is this water safe for my horses, cattle, or sheep?

E. coli, nitrate, nitrite, fluoride, salinity, and a full 14-metal suite — the parameters that affect animal health, voluntary water intake, and production performance. Relevant for bore, dam, and creek sources used for stock water where no monitoring is in place.

Recommended: Livestock & Equine Water Screen

03

I'm buying, or have recently purchased, a rural property

The property audit kits test each water source on the property in a single submission — bore assessed against drinking, irrigation, and livestock standards simultaneously; tank against drinking water standards; dam or creek against irrigation and livestock standards.

Recommended: 3-Point Property Audit · 5-Point Property Audit

04

I need to compare water sources before committing to infrastructure

The 5-Point Irrigation Audit maps salinity, sodium hazard, iron, and manganese across any combination of five bore, dam, or surface water sources in a single submission — before pump selection, pipe layout, or drip system installation.

Recommended: 5-Point Irrigation Audit

Farm Water Testing Kits

Five kits, each built around a specific question. The entry screens — irrigation suitability and livestock safety — cover a single source. The property audit kits cover three or five sources in a single submission, with each source assessed against the standard relevant to its intended use. The 5-Point Irrigation Audit maps quality across up to five bore, dam, or surface water sources before infrastructure decisions are made. Select the kit that matches your situation, or use the guide above if you're not sure where to start. All kits include prepaid express return shipping, NATA-accredited laboratory analysis, and a plain-English results report compared against the relevant published Australian and international standard.

Microbiology samples — dispatch & holding time E. coli and Total Coliform analysis requires your sample to reach the laboratory within 24 hours of collection. Collect and post on a Monday or Tuesday only using the included Express Post return bag. Customers in major cities and direct AusPost Express hubs generally meet this requirement. Customers in more remote or rural locations should be aware that transit times may exceed 24 hours — in this case microbiology results are reported as indicative rather than NATA-certified. All chemistry, metals, and herbicide parameters are unaffected by transit time.

All prices include GST · Return shipping included · NATA-accredited laboratory analysis · Results compared against ANZECC/ARMCANZ 2000, FAO irrigation guidelines, and ADWG V4.0 as applicable · Results within 5–7 business days of laboratory receipt

Every kit includes a colour-coded results report comparing each measured parameter against the relevant Australian guideline for how that water will be used — drinking, irrigation, or livestock — so you can see at a glance what was found and whether it's within the accepted range.

The 3-Point Property Audit applies all three sets of standards in a single report, matched to each source. The bore is assessed against drinking, irrigation, and livestock standards simultaneously. The rainwater tank against drinking water standards. The dam or creek against irrigation and livestock standards.

Specific references: Australian Drinking Water Guidelines V4.0 (ADWG V4.0) for drinking water; ANZG 2023 Chapter 9.2 for irrigation; ANZECC/ARMCANZ 2000 Chapter 4.3 for livestock.

Your report includes a formatted results PDF with all parameters, measured values, units, detection limits, and guideline comparisons, plus the original NATA-endorsed certificate of analysis — the formal laboratory record of your results.

Common Questions

It depends on your water source and what question you're trying to answer.

Single source, irrigation focusIrrigation Suitability Screen ($439 inc. GST). Salinity, SAR, iron, manganese, and boron — the parameters that determine whether bore or dam water is suitable for crops, orchards, pasture, and drip irrigation systems.

Single source, horses or livestockLivestock & Equine Water Screen ($549 inc. GST). E. coli, nitrate, nitrite, fluoride, salinity, and a full 14-metal suite compared against ANZECC/ARMCANZ 2000 livestock guidelines.

Buying or settling on a rural property3-Point Property Audit ($1,299 inc. GST). Bore, rainwater tank, and dam or creek tested in a single submission, each assessed against the standard relevant to its intended use.

Larger or more complex property — multiple bores, dams, or seasonal creeks5-Point Property Audit ($1,549 inc. GST). Five sources, single submission.

Multiple irrigation sources to compare before infrastructure decisions5-Point Irrigation Audit ($1,199 inc. GST). Salinity, SAR, iron, manganese, and boron mapped across any combination of five bore, dam, or surface water sources.
They answer different questions and cover different scope.

The Livestock & Equine Water Screen tests a single water source — one bore, dam, trough, or creek — against ANZECC/ARMCANZ 2000 livestock guidelines. It's designed for an existing property owner who wants to know whether a specific source is suitable for their animals.

The 3-Point Property Audit tests three separate sources in a single submission — typically bore, rainwater tank, and dam or creek — with each source assessed against the standard relevant to how it will actually be used. The bore is compared against drinking, irrigation, and livestock standards simultaneously. The rainwater tank against drinking water standards. The dam or creek against irrigation and livestock standards.

If you are buying a property or have recently purchased one and want a complete picture of all your water sources, the property audit is the right choice. If you own the property and have a specific concern about one source, the single-source screen is more appropriate.
Yes — that's exactly what the 3-Point Property Audit is designed for. One kit contains sampling bottles for all three sources, a single prepaid return bag, and a single chain of custody form. All three samples are submitted together and your report covers all three sources.

If your property has more than three water sources — a second bore, a seasonal creek, a header tank — the 5-Point Property Audit covers up to five sources in the same single submission.
PFAS testing is not included in our standard farm water kits but is available on enquiry for properties where there is a specific reason to test.

PFAS testing is worth considering if your property is near any of the following:

— A RAAF base or civilian airport (PFAS-containing firefighting foam was used at most Australian airfields)
— A former fire training ground
— Industrial land with a history of manufacturing, chemical processing, or AFFF use
— Agricultural land with a history of biosolid (sewage sludge) application

PFAS compounds migrate from surface contamination into groundwater and persist indefinitely. They are colourless, odourless, and tasteless at concentrations that exceed guideline values — physical appearance of the water gives no indication of PFAS presence.

Contact us to discuss PFAS testing options for your property.
Detailed sampling instructions are included in every kit. As a general guide:

Dam water — collect from just below the water surface, at least one metre from the bank. Avoid disturbing bottom sediment. If water is drawn from depth via a pump, collecting from the pump outlet is acceptable and often more representative of the water your livestock or irrigation system actually receives.

Creek or river — collect mid-stream, at the point of use, away from banks and still water. Avoid collecting during or immediately after heavy rain events — results during runoff conditions are not representative of baseline water quality.

Microbiology bottles require special handling — see the holding time note below the kit tables for dispatch instructions.
SAR stands for Sodium Adsorption Ratio — a calculated value derived from your sodium, calcium, and magnesium results. It measures the relative proportion of sodium to other cations in the water.

High-SAR water applied to soil over time causes sodium to displace calcium and magnesium from soil particles. The result is progressive soil structural breakdown — reduced permeability, surface crusting, and compaction — which reduces water infiltration and can make soils difficult to work. The effect is most pronounced on clay and clay-loam soils and accumulates over multiple irrigation seasons.

SAR is compared against FAO irrigation guidelines in all kits that include irrigation chemistry. It is one of the most important parameters for assessing long-term bore water suitability for irrigation.
Appearance and taste are unreliable indicators of water quality for agricultural or drinking purposes.

Most of the parameters that matter for irrigation — sodium hazard (SAR), elevated boron, residual herbicides — are colourless and tasteless at agronomically significant concentrations. Arsenic, fluoride, nitrate, and PFAS produce no noticeable change to the appearance, smell, or taste of water at concentrations that exceed their respective guideline values. E. coli contamination is similarly undetectable without testing.

Bore water in Australia has no regulatory monitoring requirement. Nobody is checking it on your behalf.
The report states whether each measured parameter is above or below the published guideline value from ADWG V4.0 — Australia's national drinking water guidelines, produced by NHMRC and NRMMC.

We report the results and the comparison against the published standard. We don't make suitability determinations — that assessment is for you, in consultation with your health professional, based on the factual results your report contains. The NATA-endorsed certificate of analysis included with every report is the formal record of your results.
For an established bore used for drinking or irrigation, annual testing is reasonable baseline practice. Groundwater chemistry is generally stable year-to-year, but can shift with drought, significant drawdown, nearby drilling activity, or changes to surrounding land use.

Re-testing is worth considering after:

— A significant flood or heavy rainfall event (particularly for dam and surface water)
— Nearby agricultural chemical application
— A change in neighbouring land use (new feedlot, new irrigated crop, earthworks)
— Noticeably different water appearance, taste, or odour
— Any change to the bore itself — new pump, deepened, or recased

For livestock water from dams or creeks, biannual testing — before summer and before winter — gives a more complete picture of seasonal variation.
Yes. E. coli and Thermotolerant Coliform samples must reach the laboratory within 24 hours of collection to meet NATA accreditation requirements.

Collect and post on a Monday or Tuesday only, using the included Express Post prepaid return bag. This ensures your sample reaches the laboratory before the end of the working week. Samples collected Wednesday through Sunday cannot reliably meet the 24-hour requirement via AusPost Express.

Customers in major cities and towns with direct AusPost Express connections generally meet the holding time. Customers in remote or rural locations should be aware that transit times may exceed 24 hours despite express posting — in this case your microbiology result is reported as indicative rather than NATA-certified.

All chemistry, metals, and herbicide parameters are unaffected by transit time and are reported to full NATA accreditation regardless of when your sample arrives.
