Environmental

Environmental Department was one of the first services developed at CLS together with the food and water microbiology department.  This area has been successfully supplying contract sampling and analysis to public and private sector clients since 1996, including fresh & saline waters, soil, sludge and dust.

CLS provides a wide range of environmental sampling (ISO 5667) and analysis both of which are ISO 17025 accredited (108T) and ISO 9001:2015 approved. We operate our own fleet of refrigerated vans nationwide taking full chain of custody management on behalf of our clients and make our results available online 24/7 as the tests are validated at our labs. Our clients can access their results and trend their own data using our systems. We have customised reporting available and work with large projects to integrate data for maximum efficiency. EDEN data uploads are also available.
