Notes
1. All values in μg/g unless otherwise stated. Substances must be analyzed using methods specified in a director's protocol or alternate methods acceptable to the director.
2. The site-specific factors of human intake of contaminated soil and toxicity to soil invertebrates and plants specified in this matrix apply at all sites.
3. Standards have been derived based on results of clinical studies at sites. Standards represent the rounded sum of the toxicologically-based value plus the applicable soil ingestion clinical study factor, if one is available. For AL, PL, and RL, the soil ingestion clinical study factor is 80 µg/g. For CL, the soil ingestion clinical study factor is 240 µg/g. For IL, no soil ingestion clinical study factor is available. For IL, the toxicologically-based value without addition of a clinical study factor approximates the CL soil standard, therefore the IL standard was set equal to the CL standard.
4. Intake pathway of exposure modeled is inadvertent ingestion of soil.
5. Standard has been adjusted based on a reference provincial background soil concentration. Standard represents the rounded sum of the toxicologically-based value plus the reference provincial background soil concentration. For all land uses, the reference provincial background soil concentration is 14.9 μg/g.
6. NS — no standard. Insufficient acceptable scientific data exists, so no standard is calculated.

Notes
1. All values in μg/g unless otherwise stated. Substances must be analyzed using methods specified in a director's protocol or alternate methods acceptable to the director.
2. The site-specific factors of human intake of contaminated soil and toxicity to soil invertebrates and plants specified in this matrix apply at all sites.
3. For AL, PL and RL, if the land is used to grow produce for human consumption, the standard is 3 μg/g, if not, the standard is 35 μg/g. For CL and IL, standards are applicable only to land that is not used to grow produce for human consumption.
4. Standards have been derived based on results of clinical studies at sites. For AL, PL and RL, the 3 μg/g standard represents the rounded remainder of the toxicologically-based value (35 μg/g) minus the soil ingestion clinical study factor (32 μg/g). For CL, the standard was set equal to the soil ingestion clinical study factor (100 μg/g). For IL, no soil ingestion clinical study factor is available, therefore the IL standard was set equal to the toxicologically-based value.
5. Intake pathway of exposure modeled is inadvertent ingestion of soil.
6. The pH is the pH of the soil at a site.
7. Standard has been adjusted based on a reference provincial background soil concentration. Standard represents the rounded sum of the toxicologically-based value plus the reference provincial background soil concentration. For all land uses, the reference provincial background soil concentration is 1.3 μg/g.
8. NS — no standard. Insufficient acceptable scientific data exists, so no standard is calculated.

Notes
1. All values in μg/g unless otherwise stated. Substances must be analyzed using methods specified in a director's protocol or alternate methods acceptable to the director.
2. The site-specific factors of human intake of contaminated soil and toxicity to soil invertebrates and plants specified in this matrix apply at all sites.
3. Intake pathway of exposure modeled is inadvertent ingestion of soil.
4. Standards have been derived based on results of clinical studies at sites. Standards represent the rounded sum of the toxicologically-based value plus the applicable soil ingestion clinical study factor, if one is available. For AL, PL and RL, the soil ingestion clinical study factor is 385 µg/g. For CL, the soil ingestion clinical study factor is 650 µg/g. For IL, no soil ingestion clinical study factor is available, therefore the IL standard was set equal to the toxicologically-based value.
5. The pH is the pH of the soil at a site.
6. Standard has been adjusted based on a reference provincial background soil concentration. Standard represents the rounded sum of the toxicologically-based value plus the reference provincial background soil concentration. For all land uses, the reference provincial background soil concentration is 108.6 μg/g.
7. NS — no standard. Insufficient acceptable scientific data exists, so no standard is calculated.

Notes
1. All values in μg/g unless otherwise stated. Substances must be analyzed using methods specified in a director's protocol or alternate methods acceptable to the director.
2. The site-specific factors of human intake of contaminated soil and toxicity to soil invertebrates and plants specified in this matrix apply at all sites.
3. Intake pathway of exposure modeled is inadvertent ingestion of soil.
4. The pH is the pH of the soil at a site.
5. Standard has been adjusted based on a reference provincial background soil concentration. Standard represents the rounded sum of the toxicologically-based value plus the reference provincial background soil concentration. For all land uses, the reference provincial background soil concentration is 138.1 μg/g.
6. Standard is set equal to the Canadian Council of Ministers of the Environment, 1999 - Nutrient and energy cycling check value.
7. Standard varies with receiving water hardness (H). H = 100 — < 200 mg/L as CaCO3 is assumed. Consult director for further advice.
