Appendix E<br />
contaminant concentration in <strong>the</strong> receiving soil (assumed to be a background concentration initially) to<br />
<strong>the</strong> residential/parkl<strong>and</strong>/commercial l<strong>and</strong> use guideline:<br />
C i = 14.3 × SQG RPC - 13.3 × BSC [3]<br />
It follows that a soil quality guideline <strong>for</strong> <strong>the</strong> industrial site that exceeds C i may endanger surrounding<br />
l<strong>and</strong> that is under a more sensitive use because <strong>of</strong> <strong>the</strong> threat <strong>of</strong> erosion <strong>and</strong> subsequent <strong>of</strong>f-site<br />
deposition. There<strong>for</strong>e, if <strong>the</strong> PSQG HH <strong>for</strong> <strong>the</strong> industrial site exceeds C i , SQG HH should be set at C i .<br />
Conversely, if PSQG HH <strong>for</strong> <strong>the</strong> industrial site is less than C i , SQG HH should be set at <strong>the</strong> PSQG HH<br />
A review <strong>of</strong> nine metal contaminants showed that C i calculated by equation (3) averaged 12 times <strong>the</strong><br />
magnitude <strong>of</strong> <strong>the</strong> interim residential/parkl<strong>and</strong> guidelines. There<strong>for</strong>e, to protect against <strong>of</strong>f site<br />
contamination, it is recommended that commercial <strong>and</strong> industrial l<strong>and</strong> use guidelines <strong>for</strong> stable<br />
contaminants be capped at 15X <strong>the</strong> residential/parkl<strong>and</strong> l<strong>and</strong> use guidelines.<br />
