NCIMB is an Aberdeen-based microbiology and analytical services company that has been working with the oil & gas sector since the early days of the North Sea Industry, developing services to support companies tackling challenges associated with the different stages of North Sea activity. We offer ecotoxicity testing of effluents and other substances discharged in association with decommissioning activities. Effluents associated with decommissioning are often a complex mix and so whole effluent toxicity testing is an ideal approach. Our MARA and LumiMARA ecotoxicity tests have been recommended by BEIS for produced water testing and can also be used to test discharges that may be associated with decommissioning. Our laboratories also offer a suite of commonly required effluent tests.
