Fill Soils
Ecowaste has established the following concentration limits for Residential and Industrial Grade Fill Soils. All limits are expressed as µg/g on a dry weight basis (µg/g = mg/kg or ppm).
For any elements or compounds not shown, the values given in the Contaminated Sites Regulation and subsequent amendments apply.

Waste Soils
Waste Soils accepted by Ecowaste must not be Special Wastes. Acceptable waste soil generally has a minimum number (1 - 3) of substances exceeding the Ecowaste Industrial Limit. The average for any substance is normally not more than twice the Ecowaste Industrial Limit, with no single value more than 5 or 10 times the Ecowaste Industrial Limit. These are guidelines only as the acceptance of any soil will be established by Ecowaste on site-by-site basis.
Waste soil containing remediable hydrocarbons will not be accepted until the hydrocarbon levels are reduced to below the Ecowaste Industrial Limit.
History of Revisions
March 3, 2002 - Arsenic reduced from 60 mg/kg to 20 mg/kg for both Residential and Industrial Grade Fill Soils based on Second Stage Amendments to Contaminated Sites Regulation
April 6, 2005 - changed reference from "Second Stage Amendment ... " to "subsequent amendments apply".
