Sampling is therefore undertaken using pumped samplers, located at monitoring stations operated within the Automatic Urban and Rural Network (AURN)The Environment Agency (EA) on behalf of United Kingdom Department for Environment, Food and Rural Affairs (DEFRA) requires a Supplier to provide the Central Management and Control Unit (CMCU) and the Quality Assurance and Quality Control (QA/QC) for the UK Hydrocarbon Monitoring Network.The Monitoring contracts team within Survey, National Monitoring has been managing the UK Hydrocarbons Network contract on behalf of DEFRA since April 2016.
