Natural attenuation processes are well documented for unconsolidated sands. However, monitored natural attenuation (NMA) has not been well documented in sandstone common in the UK. SIReN is an initiative between Shell Global Solutions, Environment Agency, CL:AIR-E and AEA Technology established to provide: (a) a study of MNA in UK hydrogeology (made ground, potentially dual-porosity aquifer); (b) a site for co-ordinated research into MNA; (c) a contribution towards defining an operating window for MNA in the UK; (d) a cost-effective MNA strategy for "mega" sites, addressing the challenges of multiple sources/co-mingled plumes. SIReN has a 50-year history of petrochemicals manufacture. Contaminants include BTEX, styrene and naphthalene. Site characterization detected co-mingled plumes in shallow groundwater, and found evidence of penetration to the sandstone aquifer. A number of research projects are ongoing, covering a broad range of themes, including: "Smart" monitoring/site investigation; decision-making tools for MNA; and specific remediation technologies. Site characterization as well as initial findings from research are presented with discussion of MNA strategy for complex "mega" sites.
