“You are never going to get zero Legionella Bacteria, but we can not allow it to concentrate up. We need to monitor and treat it. The goal isn’t no Legionella, the goal is no Legionnaires Disease.” – Trace Blackmore, CWT

A water management plan, in my opinion, is something that everybody should have.

Just testing the client’s water is not a water management plan.” – Trace Blackmore, CWT

“You need to build trust with your client and that means having a plan for what to do if a system tests positive for Legionella with your client before it happens.” – Trace Blackmore, CWT
