Ontario leachate quality criteria
Arsenic
Ontario TCLP limit: 2.5 mg/L for Arsenic.
ComplyOnSiteIs Ontario D004 hazardous waste?
Yes, when the leachate limit is met. The Ontario leachate-toxicity limit for arsenic is 2.5 mg/L in the TCLP extract. The limit is inclusive, so a result at the limit meets this constituent’s criterion, subject to the regulation’s exclusions. A concentration in the original bulk waste is a different measurement.
For a subject-waste shipment, the generator records the 3-digit class and primary characterization in the waste-number details of the Ontario hazardous waste manifest. This hazardous-waste number names the constituent for the regulatory assessment and doesn’t replace that class-and-letter waste number. Land-disposal treatment standards are assessed separately.
What does Ontario D004 cover?
This number is for arsenic in the extract from the Toxicity Characteristic Leaching Procedure. The classification limit is 2.5 mg/L. It isn’t tied to any source industry, container or physical form, and Ontario sets land-disposal treatment requirements separately.

Does arsenic make waste Ontario D004?
| Code | When it fits |
|---|---|
| D004 | The TCLP extract holds 2.5 mg/L or more. |
| This constituent criterion not met | The TCLP extract is below 2.5 mg/L. Other hazardous criteria still need assessing. |
A below-limit result for one constituent doesn’t clear other constituents, characteristic hazards or listed-waste rules. Apply the classification threshold first, then the separate land-disposal treatment standard.
Which wastes take Ontario D004?
| Waste | When it’s D004 |
|---|---|
| Contaminated soil | When the measured extract reaches the limit for this constituent. |
| Treated wood | When the measured extract reaches the limit for this constituent. |
