Our laboratories

SEPA has a network of four chemistry laboratories and seven biology laboratories, with more than 2,500m2 of lab space, £12m worth of scientific equipment (excluding our hydrometric network) and a survey vessel with a fleet of smaller craft.

Our experts cover many fields of science, including hydrology, chemistry, ecology, algology, ecotoxicology, hydromorphology, hydrogeology, and oceanography. Our scientists analyse a wide range of samples collected from across Scotland's air, land and water environments. We test for more than 500 individual chemical parameters and the levels of 2,000 plants and animals in marine, freshwater and terrestrial habitats. We also conduct analyses of solid waste arisings and audit check analyses of gaseous emissions to atmosphere.

In a typical year, we collect around 50,000 samples and deliver 700,000 determinations to support our statutory monitoring (EC directives), our general duty to assess and report on the state of Scotland's environment, and our duty to inform and assess compliance with licence conditions.
