HC Info provides consulting services related to Legionella and other waterborne pathogens to owners, attorneys, and manufacturers. We also partner with engineering firms, environmental consulting firms, and water treatment companies.

Qualifications: Our work is managed by Matt Freije utilizing some of the world's leading experts in Legionella control, water chemistry, chlorine dioxide applications, filtration, and metallurgy.

Unbiased: We do not sell or profit from the products or services (chemicals, equipment, filters) we recommend.

We can help you...

  • Investigate Legionnaires disease. We will help you get the situation under control quickly and then solve the root problem. We can interpret your Legionella test results, oversee emergency disinfection (if necessary), design a sampling program, help you deal with the press and health departments, and recommend a long-term remediation strategy that fits your situation.
  • Solve Legionella problems in plumbing systems. No single remedial strategy is best for all systems because a number of factors must be considered. We will help you choose the best domestic (potable) water remediation strategy--chemical disinfection, system operation and design, water temperatures, filters--for your situation. We do not sell chemicals or equipment so our recommendations are unbiased. You will save hours of research time, thousands of dollars, and perhaps a lot of embarrassment.
  • Obtain an expert opinion. Matt Freije has been retained as a Legionella expert by plaintiffs and defendants in more than 50 cases since 1999, with deposition and trial testimony.

Pay for only what you need. We might be able to solve your problem on the phone or least point you in the right direction. You can pay for a conference call or two and then decide where to go from there.
