• Inhalation of ground gas and soil gas; • Vertical and lateral migration of
leaching);
• Root uptake; and • Chemical attack of infrastructure (including cable) and buildings.
3.7.3 Potential Sensitive Receptors
Sensitive receptors relating to this project include: • Adjacent site users; • Vegetation;
• Perched groundwater beneath the Preferred Onshore Cable Corridor/converter station;
• Deeper groundwater (principal, secondary A and secondary B aquifers); • Surface watercourses (including manmade drainage); and • Buildings and infrastructure (proposed and existing).
Please note that construction workers have not been identified in the CSM as receptors because risks can be appropriately managed through health and safety procedures, including CDM regulations.
3.7.4 Potentially complete pollutant linkages
The outline CSM is shown schematically in Figure 20.1.5 and an estimate of the risk associated with each linkage is summarised in Table 6. The risk classification has been undertaken in accordance with CIRIA C552 (Rudland et al., 2001), a summary of which is included in Appendix C to this report.
