Case Study:
Liability to Resolution – A Strategic Approach to Illegal Soil Dumping

Environmental Compliance | August 2026

Discovering unauthorized soil stockpiles on your property is more than just an eyesore, it’s a significant environmental and financial liability.

 

 

Recently, ECOH was engaged by a client facing this exact challenge. The primary concern? Managing unknown materials while ensuring full compliance with the Ontario Excess Soil Regulation (O. Reg 406/19).  Upon inspection, we found the stockpiles consisted of a complex mix of excavated soil and various construction materials, including concrete, wood, and debris.

 

 

Our Approach: Tech-Driven, QP-Led

Effective soil management starts with accurate data. To gain a clear understanding of the site’s scope, our team deployed aerial drone technology.
This allowed us to:

  • Visualize the Footprint: Capture high-resolution aerial imagery to map the total volume and distribution of the dumped soil.
  • Targeted Characterization: Move beyond guesswork. Working as a Qualified Person (QP), we designed and implemented a targeted sampling and analysis plan to perform professional Soil Characterization. This process is essential to define soil quality and determine appropriate, compliant disposal or reuse pathways.

 

 

 

 

The Outcome

By combining aerial mapping with technical field expertise, we provided our client with a clear, defensible path forward. We transformed an unpredictable “liability” into a structured, manageable project, ensuring regulatory compliance and preventing further environmental risk.

Whether you are performing a Site Assessment for a new development or investigating unexpected site impacts, ECOH provides the technical oversight and regulatory expertise you need to proceed with confidence.
