Water Microbiology – Sample Description

Samples are simulated stabilized waters that can be assessed by membrane filtration, MPN, or other assays.

Drinking and HPC Water Samples

Laboratories receive a 10mL simulated water sample which is diluted before processing by the laboratory’s own methods.

Challenges are directed towards detection, enumeration and identification of total coliforms, fecal coliforms and E.coli, Enterococcus species and Pseudomonas aeruginosa.

Recreational Water Samples

Laboratories receive a 10mL simulated water sample which is diluted before processing by the laboratory’s own methods. Simulated recreational water samples include Enterococcus faecalis as an indicator for marine waters, E.coli for Freshwater beach samples and Pseudomonas aeruginosa for recreational waters samples from spas and swimming pools.
