Unmatched Expertise in Forensic Engineering
What Is Forensic Engineering, and Why Does It Matter?
Forensic engineering involves investigating materials, products, structures, or systems that fail or do not operate as intended. These failures often become legal matters—particularly in construction defects, environmental violations, and public health cases.
Bonneau Dickson’s forensic engineering services focus specifically on:
- Wastewater treatment failures
- Septic system design flaws or malfunctions
- Water pollution and contamination disputes
- Code violations in water treatment systems
Real-World Application: A Septic System Dispute
In one case in rural California, a homeowner sued a developer for a faulty septic system that caused groundwater contamination. Bonneau was brought in as an expert witness to analyze the original design, evaluate installation practices, and provide clear, evidence-based testimony. The result? A favorable settlement based on Bonneau’s detailed engineering report and courtroom presentation.
Why This Expertise Wins Cases
Bonneau’s findings are rooted in science and supported by decades of professional practice. He understands both the technical side and the legal side, which is crucial when you need your expert to explain findings in ways that are both legally defensible and understandable to laypeople.

Bonneau has designed, reviewed, and investigated wastewater treatment systems for commercial, residential, and municipal clients. His understanding of regulatory codes, environmental compliance, and engineering best practices make him invaluable in disputes involving:

Whether it’s a large-scale municipal wastewater facility or a single-family home’s septic tank, Bonneau knows how these systems should function—and what happens when they don’t.
