Excavation Sampling Frequency of Walls and Floor

Information Last Updated - November 22, 2016

In accordance with Ontario Regulation 153/04 (as amended), there is a table as follows:

Table 3 - Minimum Confirmation Sampling Requirements for Excavation


This table is typically used in Ontario when a Record of Site Condition (RSC) site requires remediation by means of dig and dump.  We tend to use it as a guideline for remediation projects that do not require an RSC. 

It is best if samples are collected from different walls. The table represents minimum sampling, therefore, additional sampling would provide greater confidence in assessing the quality of the soil.
