PROJECT OUTLINE

For Phase 1 HS2 required Air Quality monitoring of NO₂ and PM₁₀ at various locations in west and northwest London.

For Phase 2b assessment of the potential for fugitive dust generated from construction activities on nearby residences and technically review dispersion modelling undertaken by others and contribution to air quality chapters of the Environmental Statements.

OUR SERVICES

For Phase 1 HS2 identified 112 locations for NO₂ diffusion tube monitoring, sending tubes to a trusted UKAS accredited laboratory. Temple produced monthly monitoring reports. Temple also monitored PM₁₀ at up to 60 locations at and around HS2 construction sites in west and northwest London. The air quality monitoring was undertaken to identify whether construction related activities were generating fugitive dust. By monitoring in real time we could determine the extent to which construction sites were contributing to elevated concentrations and recommend measures to reduce pollutant concentrations to within acceptable limits. Temple was innovative in that email and text alerts were put in place to ensure all relevant stakeholders could receive notifications of when exceedances took place across the project.

For Phase 2b the potential fugitive dust generated from construction activities to impact nearby residences was completed in accordance with HS2 Air Quality Technical Guidance and guidance issued by the Institute of Air Quality Management. Members of the air quality team technically reviewed inputs to the dispersion modelling undertaken by others to determine the potential for air quality effects that the scheme would have, during construction and once operational.

OUR VALUE

Successfully submitted Phase 1 monitoring reports to the client. A comprehensive review of construction activities on nearby residences and technical review of dispersion modelling undertaken by others during Phase 2b.
