Legionella Contamination Assessment Report

Our site inspection consists of legionella sampling, visual observations, and testing within the suspect building/dwelling or vehiculum, Latin for “various forms of transportation”.
LCAR’s are performed through observations of some the following possible indicators: microbial evidence of biofilms, mechanical equipment deficiencies, plumbing deficiencies, water main breaks, changes in municipal water quality, water temperature fluctuations, water temperatures between 68 °F - 113°F (20°C - 45°C), or other possible indicators like water stagnation, pressure changes, and lack of water treatment.
Other considerations are historical information, building age, mechanical and plumbing design, previous historical mechanical or plumbing repairs, periodic maintenance and cleanliness. Initial assessment of the building/dwelling or vehiculum should provide enough information to formulate a Legionella sampling plan. A preliminary hypothesis is formulated from the above observations and other presented evidence. Testing of the hypothesis requires a sampling plan, which consists of collecting microbial samples and other environmental measurements. The results of microbial samples and environmental measurements are then assessed to either confirm or deny the initial hypothesis.
