Boiler Water and Legionella Testing

Sidebar Image

We are one of a few laboratories in New Zealand specifically accredited to perform boiler water tests

OSH is closely monitoring the operation of limited-attendance and unattended boilers and requires them to be tested monthly by an independent IANZ approved laboratory.

We test hundreds of boiler water, feedwater and condensate samples every year and understand that 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. A chemical imbalance can lead to corrosion and damage to the system and this damage can ultimately lead to boiler failure and injury. This is very site specific but we have the testing capability and expertise to cover all your requirements, including:

  • Ammonia
  • Chloride or salinity
  • Conductivity
  • Copper
  • Dissolved Oxygen
  • Hardness
  • Hydroxide P2 Alkalinity
  • Iron and Manganese
  • Nitrate
  • pH
  • Phenolphthalein P1 Alkalinity
  • Phosphate
  • Silica
  • Sulphide
  • Suspended Solids
  • Total Alkalinity
  • Total Dissolved Solids
  • Turbidity

Legionella Testing

Legionella species also live happily in warm water circulation systems found in retirement homes, hospitals, and swimming pool complexes. It can also live in domestic and hotel spa pools, as well as hot water cylinders that are not set at the correct temperature.

Legionella pneumophilia has been responsible for illnesses linked to air conditioning systems in buildings. Another species called Legionella longbeachae, which occurs in soils, composts and potting mixes, has recently been found to cause illness in some people.

We routinely test for Legionella in the following matrices:

Eurofins-ELS is IANZ accredited to perform Legionella tesing in Cooling Towers. We are also accredited to perform Heterotrophic Plate Count (pour plate) tests for cooling towers.

Our Legionella methodology follows the method published by the N.Z. Communicable Disease Centre, and the joint Australian/New Zealand Standard AS/NZS 3896: 2008.
