Do I Need A Ground Gas Risk Assessment?
If the site is considered at risk a Ground Gas Risk Assessment will be identified and recommended in Phase 1 Desk Study. A Ground Gas Risk Assessment is more likely to be required if the site is in close proximity to landfill sites (historical or current), heavy industrial historic land use, infilled ponds, lakes or water sources, as well as natural ones.
No matter the source of ground gas it can pose a very real threat to a development. Gases can migrate through subsoil and into buildings where it can accumulate and cause a health risk or potential explosion.
