Expert Witness for Legionella Cases

Hire Chris Nancrede for Legionella Litigation Support

Legionella cases are not simple. They often involve plumbing systems, water management, maintenance records, testing, remediation work, and questions about what should have been done to prevent people from getting sick. That is why legal teams need more than a general engineer. They need someone who understands how these systems work in the real world and is an expert on Legionella.

Chris Nancrede, EIT, ASSE 12080, has spent more than 15 years working in Legionella and waterborne pathogen control. Chris holds a bachelor’s degree in Mechanical Engineering, an MBA from Vanderbilt University, and is a patent holder for the Legionella Dominator™. His work includes root cause analysis, system review, remediation planning, and long-term risk reduction. He has worked in hospitals, commercial buildings, industrial sites, hotels, and government facilities, the main places where Legionella outbreaks often happen.

Why Chris Is a Strong Expert Witness

Chris brings both in-depth technical knowledge and real field experience. He does not come at a case from one narrow product or one favorite treatment method. He looks at the facts, the system, the records, and the decisions that were made.

In litigation, an expert witness needs to be credible. They need to explain what happened, what standards applied, and whether the response was reasonable. Chris does that based on engineering, site conditions, and industry guidance such as ASHRAE 188.

Experience That Fits Legionella Claims

Chris has worked on Legionella issues in a wide range of facilities, including healthcare buildings, senior living settings, jails, prisons, manufacturing plants, large commercial properties, and other complex water systems. He has experience with:

• Legionella outbreak investigations
• Root cause analysis of water system failures
• Water management plans
• Legionella testing and review of testing strategy
• Remediation planning and execution
• Long-term monitoring and risk reduction

Because he has worked directly with these Legionella outbreaks in real buildings, he can explain what was missed, what should have been done differently, and whether the people in charge responded in a reasonable way.

For Plaintiff or Defense

Chris is available to work with either side.

For Plaintiff Cases

• Review whether negligence may have played a role
• Evaluate whether a facility had an adequate water management program
• Identify failures in design, maintenance, monitoring, or response
• Prepare expert opinions and reports
• Support deposition and trial testimony

For Defense Cases

• Review whether the facility met industry expectations
• Examine whether other causes or contributing factors may be involved
• Assess whether control measures were reasonable
• Challenge unsupported claims from opposing experts
• Provide rebuttal opinions and testimony

His role is not to force a conclusion or an agenda. His role is to study the facts and explain them clearly in terms that everyone can understand.

Technical Areas He Can Address

Chris can speak to many of the technical issues that come up in Legionella litigation, including:

• Water management programs
• ASHRAE 188 and related guidance
• Secondary disinfection systems
• Biofilm and Legionella growth conditions
• Testing methods and validation strategy
• Remediation methods
• Plumbing design and operating issues that affect risk
• Healthcare facility requirements

He also understands how risk can change from one jurisdiction to another, which can matter in some cases.

Clear Communication Matters

A good expert witness needs to do more than understand the technical side. He also has to explain it in a way that lawyers, judges, juries, and insurance representatives can follow. Chris is able to break down complicated water system issues into plain language that non-experts can understand without losing the technical point.

That includes:

• Clear explanations of what happened
• Organized and defensible reports
• Help during case development
• Deposition and trial testimony that stays grounded in the facts

Nationwide Support

Chris is based in Indianapolis and works with clients across the United States. He can assist with cases involving hospitals, hotels, apartments, long-term care facilities, commercial buildings, industrial facilities, and other properties where water system conditions may have contributed to Legionella exposure.
