Service Description:

The SRF subsoil domain dataset is a broad-scale cartographic representation of the subsoil composition of Ireland with associated geochemical trigger values. The individual domains or units define areas of subsoil derived from similar bedrock sources. The domains thus comprise areas with broadly similar subsoil geochemistry. Data from the National Soils Database (NSDB) (EPA-Teagasc 2007) have been used to characterize each domain geochemically in order to set appropriate threshold or trigger levels for acceptance of waste soil and stone at licensed SRFs.

The mapped boundaries are based on the Teagasc-EPA subsoils map, which comprises 67 distinct subsoil compositional classes that are described according to the geological or bedrock parent material of the subsoil. Some classes, such as “alluvium”, “peat”, “made ground” and “bedrock”, cannot be described with reference to a subsoil parent material. For these classes, the underlying bedrock has been employed in place of the absent parent material classification.

The individual subsoil classifications were amalgamated to produce seven domains. Amalgamation of subsoil classes was based on similarity of parent material in terms of composition and age. The domain map was joined to the 1310 soil samples in the NSDB and each sample was classified by domain. For each domain, the geochemical trigger values for seven elements of interest (As, Cd, Cu, Hg, Ni, Pb and Zn) were calculated from the NSDB samples contained within that domain. Trigger values are defined as the 98th percentile value of the dataset for each domain.
