What we do

SEPA has a statutory duty to report on the condition of Scotland's environment. We publish a range of environmental information and advise Ministers, partner bodies, industry and the public on environmental issues.

Our Environmental Science (ES) Directorate provides scientific, advisory and support services to SEPA. This is founded on integrated high quality measurements of the chemical, ecological and hydrological state of Scotland's environment, analytical expertise, professional scientific advice and balanced assessments suitable to record environmental change, manage the environment, advocate improvements and inform sound regulation.

ES has a number of objectives to support SEPA's outcomes, which are to:

  • monitor Scotland's environment
  • deliver scientific information that is accessible, quality assured and fit for purpose
  • provide a sound understanding and an impartial view of the state of Scotland's environment
  • provide integrated scientific advice using best available understanding and knowledge
  • anticipate future environmental trends and develop the services to meet changing requirements
  • work continuously towards higher consistency, effectiveness and efficiency
  • take a proactive approach to effecting environmental improvement, protecting human health and achieving SEPA's environmental outcomes.

Our Monitoring Plan is a purpose built electronic database system - National Environmental Monitoring System (NEMS). For Hydrological data we use the Hydrology Information Management System (HIMS).

The details of 'where, when and what for' are held within NEMS. For example, each geographic sample or sample site is given a unique identifier location code. NEMS provides information on where monitoring takes place, when it should or has taken place and the analysis results. NEMS is the master and only source for SEPA's national Monitoring Plan and Monitoring Schedule.

These databases are the working systems for enacting ES monitoring, working with sample scheduling (also inspections), analysis and reporting. Performance reporting on the plan's achievements is undertaken by various business planning and management processes, which are monitored and reported on a monthly or quarterly basis via NEMS and HIMS.
