Mycometer surface Bacteria (MSB) is a method for estimating the level of bacteria on a surface. Results are divided into 3 interpretation categories: A, B and C, derived from the investigation of surfaces in non-flooded buildings. It is a tool for separating areas contaminated with bacteria after flooding or sewage leakage from non-contaminated areas. Secondly, as a tool for ensuring successful cleaning (PRV). 

Examples:

Case 1 shows results taken from surfaces in a basement after a sewer water leak and before any remediation has been done.

Room 2 and 3 show high levels of bacteria and are contaminated. There is no indication that room 1 has been contaminated by sewer water.

Case 2 shows results taken for post remediation verification on surfaces after cleaning on concrete floor in room 2 and 3.

Case 1 and 2 demonstrate that the MSB is a good way to locate and document surfaces contaminated with bacteria, and to document a successful PRV.
