Protocol for the Derivation of Environmental and Human ... - CCME

Part C, Section 4
The generic industrial scenario envisioned by the Subcommittee is a factory site where goods are
produced. For industrial land uses, public access is assumed to be both controlled and limited, and
those typically spending the greatest time on-site would be working adults. The sensitive receptors for
industrial land uses is therefore a working adult. Adults consume one quarter of the soil typically
consumed by children, and have about five times the body mass to distribute the chemical. Adults as
critical receptors, coupled with assumed exposure period used for industrial lands, will result in industrial
guidelines generally being greater than those for agricultural and residential/parkland land uses.
Derivation of high soil quality guidelines concentrations for industrial sites could result in contamination of
local residential sites through the off-site migration of soils and dust. This potential off-site migration will
be checked with the procedure contained in Appendix E. As with other land use scenarios,
groundwater sources of drinking water, and possible industrial water usage such as food processing,
should be protected. Soil quality guidelines will be established that are likely to protect drinking water
quality for the groundwater below an industrial site remediated to generic guidelines. The exposure
assumptions for industrial land uses are shown in Figure 23.
