​Watercare’s laboratory operations are driven with a focus on improving processes and results for clients. As part of this focus, we work to derive the maximum benefit from current technologies whilst also researching and reviewing emerging technology. This view on the use of technology is applied to every process within the laboratory – from initial analysis and delivery of results, through to quality control and air conditioning configurations to eliminate airborne contaminants.  

The Laboratory Information Management System (LIMS) used by Watercare is LabPro. We are currently going through the process of upgrading our information management system to Labware which will support our future information requirements and offer customers a number of additional functions. This system is capable of tracking each sample through all stages of analysis, reporting and invoicing.


Watercare Laboratory offers ultra low metal detection limits with ICP-MS technology.

Watercare Laboratory Services uses an Agilent 7500 series ICP-MS (Inductively Coupled Plasma Mass Spectrometer) to meet the growing customer need for ultra low level metal detection in a range of matrices. The ICP-MS allows for the accurate detection of a greater range of metals to lower detection limits than earlier technologies. In most instances we will be able to reach the ppb (parts per billion) level and in some cases the ppt (parts per trillion) levels of detection. To put those measurements in perspective 1 ppb is the equivalent to 1 second in 31.7 years and 10 ppt, 1 second in 3,170 years!
