A review of the contaminant status of the Irish Sea 2005-03-15 publication BGS_SEA_84 British Geological Survey This report is a contribution to the Strategic Environmental Assessment (SEA6) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). This report considers the major sources of contamination to the Irish Sea from offshore energy installations and puts them in the context of other sources of contamination to the region. The report also considers contamination of the wider environment, making use of data provided by monitoring programmes and other specific studies. The oil and gas industry in the Irish Sea is small by comparison to that of the North Sea, but bears comparison to that of the Southern North Sea which is dominated by gas production and for which many of the platforms are in relatively shallow water. The discharge of production and drilling chemicals, residual oil and compounds derived from the formation water co-produced with the oil or gas contribute to the contamination concentration in sediments and water. However, in Liverpool Bay and Morecambe Bay, where the oil and gas fields are located, the riverine inputs of major groups of organic contaminants and metals are found to be several orders of magnitude greater than those from the offshore oil and gas industry. Inputs of artificial radionuclides into the Irish Sea are dominated by discharges from Sellafield on the Cumbrian coast. The distribution of radionuclides in seawater, in the sediment and in biota are reviewed.

Data specific to the oil and gas industry for the SEA6 area was gathered from Environmental Impact Assessments for oil and gas developments in the Irish Sea, pre and post development surveys of oil and gas production facilities in Liverpool Bay (2002), the Environmental Emissions Monitoring System Detailed Emissions Reports (EEMs, 1999-2003) and CEFAS/Dti Offshore Chemicals Notification Scheme data. Of particular importance is the data gathered as part of the United Kingdom National Marine Monitoring Programme (UK NMMP). Data for the NMMP is presented in a number of publications that include the CEFAS Aquatic Environment Monitoring Reports (AEMR) (1998, 1999-2000 and 2000- 2001), Quality Status report - Region III Celtic Seas (QSR 2000), UK NMMP second report (1999-2001) and the Charting progress: An Integrated Assessment of the State of the UK Seas report (2005). Publications of importance to radioactivity in the marine environment include the Radiation in Food and the Environment (RIFE) report, the MARINA II study (Betti et al., 2004) and the data published in the CEFAS AEMRs.
