Water Testing

It is vitally important that water is sampled and preserved correctly in order to ensure analysis results accurately reflect the in situ parameters (analytes and physical water properties) that you are trying to measure and base decisions on.

 

Envirolab Services is NATA Accredited for the testing and analysis of waters, which include, but are not limited to potable, process, groundwaters, surface waters and wastewaters.

 

Sampling and Process for Water Testing

For water testing, sampling and preservation information is fully outlined in AS/NZS 5667 as well as other sources, such as the American Public Health Association (APHA) ‘Standard Methods for the examination of water and wastewater.’ Generally, samples are best kept refrigerated and should be received at the laboratory within 24 hours of sampling. 

 

More specific information relating to sampling can be viewed on our specially prepared fact sheet on the recommended preservation and holding times for waters.

 

Sampling that meets your Unique Testing Requirements and Project Needs

Based on your needs and requirements for scientific testing services, our expert team at Envirolab can advise which analysis may best suite your situation. Our team will provide you with appropriate sample bottles and preservatives (if applicable) for you to collect and then deliver the water sample in. These bottles, along with a completed Chain of Custody form, should be delivered to your nearest Envirolab office or laboratory as soon as possible.

Organics

Organic contamination of water may originate from a variety of sources, for example fuel storage tanks, industrial processes and greenhouse emissions. 

 

Envirolab can provide reliable results for clients who are subject to process control as well as national and local regulatory compliancy. Some areas of organic analysis include:

  • VOC (Volatile Organic Compounds) - include compounds from fuel sources and chlorinated volatile hydrocarbons from historical use of degreasers.

 

  • SVOC (Semivolatile Organic Compounds) - encompasses a wide variety of compounds

    • Polyaromatic Hydrocarbons (PAHs)

    • Phenols

    • Herbicides/Fungicides

    • Pesticides

    • Polybrominated Diethyl Ethers (PBDEs)

    • Polychlorinated Biphenyls (PCBs)

    • Dioxins and Furans

    • Explosives

    • Organometallics (e.g. TBT and Methyl Mercury)

 

  • TRH / BTEX testing suite (Total Recoverable Hydrocarbons / Benzene, Toluene, Ethylbenzene, and Xylene) - useful test for determining the nature of a fuel / oil source.

Anions

Anions are commonly present in significant quantities in the majority types of waters.

 

While some anions are part of regulatory programs for improving the taste and removing odour in water, others are classed as carcinogenic and therefore need to be regulated. Anions (and cations) are also an indicator of water quality, such as soft water, compared to hard water, and the potential for concrete cancer in building infrastructure.

 

Testing for anions in water at Envirolab

Envirolab has many years of experience in providing our clients with quality scientific testing of anions including:

  • Alkalinity - as an indicator of the presence of Bicarbonates, Carbonates and Hydroxides

  • Bromide

  • Chloride

  • Fluoride

  • Nitrate

  • Nitrite

  • Oxyhalides (disinfection biproducts)

  • Phosphate

  • Sulphate

Major Cations

While naturally occurring in rocks and soils, higher concentrations of certain Cations in water may be present due to other factors, such as industrialisation. These higher concentrations of Cations may cause water to be more corrosive.

 

Within industry, the concentration of Cations in water affect pipelines, irrigation and farming equipment. For example, hard water with the build-up of Calcium and Magnesium salts. Similarly, washing, cooking and hot water systems may be affected at the consumer level.

 

Testing for cations in water at Envirolab

Common major cations that our team at Envirolab can assist you with include:

  • Sodium

  • Potassium

  • Calcium

  • Magnesium

 

 

Chelex Metals

When monitoring water quality for ecosystem protection, where water quality is affected by the presence of trace metals, the bioavailability of such metals (not just the concentration of elements in the dissolved phase), can be critical in the assessment of potential toxicity. 

 

Bioavailability1 has been defined as metals that can be taken up by and potentially cross cellular membranes. The metals retained by the selective Chelex resin in this method are deemed representative of the bioavailable metals. The method has been chosen to provide further information than a simple filtered or unfiltered analysis of the fractions of water samples using a rapid column separation.

 

Scientific Testing at Envirolab

NATA Accredited testing at Envirolab is performed to determine Chelex - Bioavailable Metal Speciation in natural waters for:

  • Aluminum (Al)

  • Copper (Cu)

  • Mercury (Hg)

  • Barium (Ba)

  • Cobalt (Co)

  • Molybdenum (Mo)

  • Beryllium (Be)

  • Iron (Fe)

  • Nickel (Ni)

  • Cadmium (Cd)

  • Lead (Pb)

  • Tin (Sn)

  • Chromium (Cr)

  • Manganese (Mn)

  • Vanadium (V)

  • Zinc (Zn)

 

Please note, the sample should be either 0.45µm or 0.1µm field filtered into an unpreserved metals (HDPE) bottle.

PFAS

As emerging environment contaminants, PFAS have been identified in water and include a class of perfluorinated compounds, Perfluorooctane sulfonic acid (PFOS), Perfluorohexane sulfonic acid (PFHxS) and Perfluorooctanoic acid (PFOA).

 

The once extensive use of PFAS in industrial applications and their use in Aqueous Film Forming Foams (AFFF) for firefighting products has resulted in extensive contamination. The high mobility of PFAS has caused detection in water bodies at significant distances from areas of use.

 

PFAS pose a concern because they do not 'break down' or decompose easily and may be present in water samples from municipal water, drinking water wells, surface water (lakes, rivers and dams) and groundwater. PFAS may also be found in soil, sediment and air either due to release from a manufacturer or by the use and disposal of products that contain these contaminants.

 

 

PFAS Testing at Envirolab

Envirolab Services is specialised in testing for PFAS.

 

Analysis is conducted by combining liquid chromatography with mass spectrometry (LC-MSMS). The LC-MSMS technology provides a fast and accurate method for detecting PFAS in a variety of sample matrices including water, soil, blood/serum and biota. Future testing in air is now feasible with international regulatory bodies developing suitable sampling and analysis techniques.

 

Apart from Envirolab’s state of the art facilities, our many years of expertise in scientific PFAS testing will assist you in your testing requirements. Additionally, Envirolab has been an early adopter to the Total Oxidisable Precursor Assay (TOPA), which may assist in determining the presence of precursor PFAS compounds i.e. PFAS that can chemically and/or biotransform into the persistent PFAS. For example, PFOS, PFHxS and PFOA.

Micro Organisms

Bacteria, pathogenic or 'disease causing' organisms and other microorganisms are a health concern when considering the safety and quality of drinking water.

 

Human and animal wastes are a source for the spread of pathogens in water areas including rivers, lakes, runoffs and contaminated swimming pools. Discharge from septic tanks, sewage treatment facilities and the natural environment are other sources for water contamination.

 

Envirolab has specialist expertise in assessing water for:

  • E.coli

  • Legionella

  • Salmonella

  • Thermotolerant coliforms

  • Total plate counts

 

Of note, Envirolab’s Perth facility, MPL Laboratories was the first commercial laboratory in Australia to be NATA Accredited for Amoebae detection, in 2014, using PCR (includes the speciation of Naegleria).

Nutrients

While vital for plant growth and stability, higher concentrations of nutrients in water sources may affect ecosystems; algae and other aquatic plants will continue to grow well beyond the amount needed to support the biological community. Consequential changes to acidity and oxygen levels may in turn be toxic to fish and other marine life.

 

Higher levels of nutrients in water are not only detrimental to an ecosystem, but also affect human health and agriculture. At the same time, residue from fertiliser used to grow crops may contaminate a downstream drinking water bore with excessive levels of nitrates and phosphates.
