Tests performed: E. coli, Thermotolerant Coliforms, Heterotrophic Plate Count
Sample collection: A sterile bottle is required and is available from our laboratories.
Please sample from a tap that the water is likely to be consumed from.
Please label the bottle, including the date and time of sampling, and then fill the bottle leaving only a small air pocket at the top. Deliver to the laboratory as soon as possible, as analysis must commence within 24 hours of sampling.
Do not freeze or allow sample to get warm, as this will affect bacteria numbers.
* Please only sample and submit for testing Monday to Wednesday. Samples won’t be accepted Thursday and Friday.
Drinking water guidelines:
– Thermotolerant coliforms (or alternatively, E.coli) should NOT be found in drinking water.
– Heterotrophic bacterial counts may indicate any degradation in water treatment efficacy.
