Geological Survey Ireland in partnership with the Environmental Protection Agency has developed Geochemically Appropriate Levels (GALs) for Soil Recovery Facilities specifically in relation to metals and metalloids in uncontaminated soil and stone. The GALs vary across the country by geochemical domain, to account for the natural variation in soil metal contents we see in Ireland. There are 7 geochemical domains encompassing the main soil parent materials and rock types.
