  • Air Quality Monitoring
    impacts changes in air quality over time whether we are progressing towards national and regional goals regional and international comparisons Eurofins New Zealand is IANZ accredited to perform a wide range of air quality tests at both indoor and outdoor sample points For outdoor samples we work with local and regional councils to monitor the following parameters Fumes and emissions Atmospheric pollution Air filters extracts or impinger solutions We work with air quality professionals and local building owners to measure the air quality within buildings The tests we perform on these samples include Particulate matter Yeasts and moulds Bacteria Physical parameters Carbon monoxide Particulate Monitoring PM 10 particles are less than 10 microns in diameter and are easily inhaled into the lungs The main sources vary significantly between regions For example in Auckland the main source is motor vehicles while in Christchurch the main source is home heating fires Other sources include industry sea spray and agricultural activities Gas measurement Sulphur dioxide SO 2 Sulphur dioxide SO 2 is a colourless gas which forms sulphuric acid when combined with water Sources include the combustion of fossil fuels containing sulphur eg coal and diesel and industrial processes such as fertiliser manufacturing aluminium smelting and steel making Sulphur dioxide also results from natural sources such as geothermal activity Nitrogen dioxide NO 2 Nitrogen dioxide NO 2 is a reddish brown gas It is not usually released directly into the air but forms when nitrogen oxide NO and other nitrogen oxides NOx react with other chemicals Nitrogen oxide is released from combustion especially of petrol in cars It also comes from the production of nitric acid welding and explosives Natural sources of nitrogen oxides include volcanoes and bacteria Metals Eurofins New Zealand is IANZ accredited to perform metals analysis on filters used in

  • Boiler Water Testing
    Click here for more information on our our e LIMS system Home Environment Testing Boiler Water Testing Boiler Water Testing In the draft Code of practice for the design safe operation maintenance and servicing of boilers a requirement is made for regular water quality monitoring of both limited attendance boilers and unattended boilers OSH require monthly tests for these boiler types and stipulate that the testing be conducted by an IANZ accredited laboratory If you supervise a limited attendance or unattended boiler then ELS can assist you with your water testing requirements Boiler water tests available The specific method of chemical treatment used varies with the type of boiler and the specific properties of the water from which the boiler feed is derived This is very site specific but ELS has the testing capability to cover all your requirements A boiler requires testing of three different water types as shown below Feedwater Boiler feedwater is sourced from many different places Some supplies come from industry owned bores and treatment plants while others come directly from a council supply however all feedwater should be analysed in order to correctly determine dose rates of treatment chemicals Water quality can change as it passes through a delivery or reticulation system so it is important to check for various parameters at point of use ie where it enters the boiler or pre treatment system Boiler feedwater is usually a combination of returned condensate plus pre treated makeup water from a softener reverse osmosis or other purification system Typical tests used for boiler feedwater include Chloride or salinity Conductivity Dissolved Oxygen Hardness Iron and Manganese pH Silica Sulphide Suspended Solids Total Dissolved Solids Turbidity Not all water supplies will require all the tests shown here and if the supply is constant the tests will not

  • Environmental Water Testing
    Testing Environmental Water Testing Environmental Water Testing Chemical and Microbiological analyses of groundwaters is important for identifying groundwater conditions contamination and drinking water quality Screening of groundwater quality usually involves a range of tests that together form a good profile of the analytes present This includes cations anions nutrients and bacteria Nutrients Analysis The usual reason for analysing natural waters is to monitor nutrient levels over time in order to identify trends These trends can indicate a contamination of natural waters which if found early enough could be corrected Nitrogen Species Nitrogen forms many different species in the environment a condition complicated by the fact that some of these species have different names The chart below can assist you with some of the terms used for nitrogen and its different states The chart shows the different relationships between the species and can be used to show alternatives ways of analysing for each species NNN is the same as Nitrate plus Nitrite and is also called Oxidised Nitrogen Dissolved Inorganic Nitrogen NNN plus Ammonia Dissolved Organic Nitrogen Total Nitrogen minus DIN Nitrate NNN minus Nitrite TKN Total Nitrogen minus NNN Total Oxidised Nitrogen is the same as NNN Phosphorus species Four forms of phosphorus are commonly analysed in New Zealand and Eurofins New Zealand is able to test for each of them by Flow Injection Autoanalyser FIA after various forms of pre treatment Dissolved Organic Phosphorus can be measured by subtracting the Dissolved Reactive Phosphorus result from the Total Dissolved Phosphorus result Groundwater and Surface Water The most common sample matrix that we perform nutrient analyses on is ground and surface waters for regional councils Nitrogen and Phosphorus are essential for the growth of organisms and can limit the primary productivity of a body of water In instances where phosphate is

  • Legionella Testing
    systems as the primary source of Legionella related illness and in April 2004 the Building Industry Authority BIA now part of the Department of Building and Housing amended the draft compliance schedule in the New Zealand Building Code Handbook This more rigorous testing regime for cooling towers is based on the current Australian New Zealand Standard AS NZS 3666 3 It expands on the current requirement of a monthly bacteriological testing of water in cooling towers by also requiring a specific Legionella bacteria test each month Legionella testing was previously required six monthly This assists building owners to demonstrate their buildings compliance for their building warrant of fitness and hence demonstrate their ongoing compliance to councils Eurofins New Zealand is IANZ accredited to perform Legionella in Cooling Towers We are also accredited to perform Heterotrophic Plate Count pour plate tests for cooling towers Legionella and circulated water systems Legionella may contaminate and grow in other water systems such as hot and cold water services They survive in low temperatures and thrive at temperatures between 20 degrees centigrade and 45 degrees centigrade if the conditions are right e g if a supply of nutrients is present such as rust sludge scale algae and other bacteria Because high temperatures kill them for building code compliance water has to be stored at temperatures greater than 60ºC irrespective of whether a mixing device is installed and delivered at not more than 45ºC in elderly people s homes early childhood centres etc and not more than 55ºC for other building uses including housing Samples from chlorinated sources must be free of chlorine achieved by adding sodium thiosulphate to the container ELS provides sample containers suitable for this use as well as sterile swabs for use around shower heads and taps Legionella and potting mix Samples

  • Landfill Analyses
    Home Environment Testing Landfill Analyses Landfill Analyses An increased public awareness of environmental contamination has resulted in recent legislative changes to the way councils operate and plan the disposal of solid and liquid waste These changes have resulted in a greater emphasis on waste minimisation needs as well as for the need to closely monitor the environmental impact of current and closed landfills The management of solid waste disposal is a high priority for councils and environmental engineers around the world and Eurofins New Zealand is ideally placed to provide the analytical needs of these systems Through our own laboratory and our partners we offer the a comprehensive range of surface groundwater and leachate analyses including Full microbiological suite Low level metals analysis by ICP MS Low level nutrient analysis Full Organic analyses Often these samples provide a special challenge to our analysts because of the different matrix interferences that may be present Experience with these samples is a prerequisite to ensure that the correct results are being identified Landfill analyses are based on Ministry for the Environment criteria and vary between locations Eurofins New Zealand operates a wide range of equipment and test methodology capable of meeting all the

  • Drinking Water Testing for Small Communities
    complacency in New Zealand about how much waterborne illness exists This brochure details some of the ways in which you can test a water supply for a wide range of important parameters It is very important to point out that New Zealand has one of the highest rates of gastro enteritis due to Campylobacter and the protozoa Cryptosporidium and Giardia in the developed world But the actual numbers are not reliably known because only a fraction of the cases are notified Most outbreaks of gastro enteritis are usually blamed on food but water is often implicated Cases of waterborne disease may often be missed because the first suspicion usually falls upon food poisoning and adequate epidemiological studies are often not done Another reason for safeguarding the quality of our drinking water supplies is the risk from emerging pathogens New pathogens are emerging steadily Humans may not have developed immunity to these if they have not been in contact with these organisms before Eurofins New Zealand offers packages of tests we call suites designed specifically around the needs of water producers and water consumers These range from extensive suites for manufacturers of bottled water right down to farm and householder water supplies Eurofins New Zealand can assist you with any analytical water quality need so please do not hesitate to contact us Small Community and Individual Drinking Water Supplies Many New Zealanders rely on untreated water sources such as bores springs streams and roof supplies to meet our drinking washing and food preparation needs 22 of New Zealanders are currently drinking water that is either contaminated by faecal matter 4 or of unknown quality 18 We offer three different suites of tests as recommended by expert panel of the New Zealand Drinking Water Standards NZDWS The suites have been established by

  • Drinking Water Testing for Councils
    human drinking water sources The NES will require monitoring and reporting of source water in order to better inform the community of the quality of their drinking water sources and to enhance regional council involvement in community water source planning It is expected that the community can then make more informed decisions about where to take water from and what activities are appropriate in their water supply catchments Treatment Plants Eurofins New Zealand has the analytical capability to assist all water treatment systems with the testing needs The testing requirements and frequencies are documented in the New Zealand Drinking Water Standards Treatment plants in New Zealand can range from the full systems used by large cities right down to simple chlorine dosing or filters Under the new drinking water standards most of these systems will require upgrading Along with the upgrade will come the need for analytical testing on a regular basis Please contact Eurofins New Zealand if you require testing for your treatment system Reticulation to Homes and Buildings Some cities have bulk reticulation networks that require additional testing This water delivery structure is most often used for larger cities with long reticulation networks The testing is often the same as for distribution zones Once a council water supply is delivered to a building then it becomes the responsibility of the building owner to ensure the quality of the water A certified back flow preventer should be installed at the boundary between council and building networks The drinking water standards have a separate section covering buildings and this should be fully understood by building owners or their consultants The intention of the amendments to the building act is twofold Protect the council reticulation from back flow contamination Protect the residents of the building from contamination due to unsecure reticulation back flow within the building or between floors It is proposed that amendments to the Building Act 1991 will require compliance schedules for drinking water The compliance schedule will be issued with the Code Compliance Certificate Compliance schedules are required to contain the ongoing testing inspection and maintenance where relevant and any action required for a system that is in non compliance For the purpose of the act a building is defined as any building or group of buildings under the same ownership management It includes schools hospitals and prisons as well as individual buildings This part of the new drinking water standards is one of the most complex and will greatly change the way in which water quality is perceived in New Zealand As a pioneer in this change Eurofins New Zealand can assist you with the testing requirements you need Distribution Under the proposed New Zealand Drinking Water Standards NZDWS a single missed sample can result in the failure of an entire distribution zone with results made public by the Ministry of Health It is therefore essential that your laboratory have a proven history the management skills and the company resources to ensure 100 compliance to the standards
