Companies and organisations we work with

This WFD assessment is one of the best that we have received.

WFD Assessment, Environment Agency

We are impressed by Thomson’s in-depth technical knowledge in this area and their enthusiasm to do a good job for us.

Dave Levell, Environment Manager, Milford Haven Port Authority

We take quality control very seriously and we follow Standard Operating Procedures (SOPs) for all laboratory processes. The fish component of the NE Atlantic Marine Biological Analytical Quality Control (NMBAQC) scheme was awarded to us based on our technical ability and high regard to quality.

Lab manager, Thomson Ecology

‘Correct identification is of paramount importance to our work at the Environment Agency; we need to be absolutely certain of the species’ ID as it influences WFD estuary fish classification scores. Thomson Unicomarine gave a quick turnaround on the project and provided us with the identifications, dissected specimens and material that we can use as teaching aids.’

Rob Hillman, Senior Environmental Monitoring Officer, Environment Agency.
