[1] The soil-specific Zn ACLs for commercial/industrial land use are provided in Appendix B, Table 1.
[2] Soil pore water is the predominant source of groundwater. As the soil pore water leaches it passes through material that can bind the contaminants (attenuation), thus reducing their concentration. Also, in the majority of cases groundwater catchments will contain both contaminated and uncontaminated soils; pore water from the contaminated soil will be diluted by that from the uncontaminated (dilution). Therefore a a dilution and attenuation factor (DAF) is used to convert soil pore water concentrations to groundwater concentrations. The fraction of contaminated land to the total area of the groundwater/aquifer catchment can be used to calculate the DAF as indicated below:
    DAF = 100 ÷ percentage of contaminated soil in catchment
[3] A = the standard residential setting with garden/accessible soils and home-grown produce contributing <10% of vegetable and fruit intake. B = residential with minimal opportunities for soil access: includes dwellings with fully and permanently paved yard space such as high rise apartments and flats. C = parks, recreational open space and playing fields: includes secondary schools. D = Commercial/industrial: includes premises such as shops and offices as well as factories and industrial sites.
