Description
This laboratory test will check your water sample for the presence of Coliform bacteria/ E.coli bacteria and Enterococci.Potable water is water that is safe enough to be consumed by humans and other animals and is also known as drinking water. Coliform and Enterococci bacteria are commonly used as a bacterial indicator of the sanitary quality of water.
- E.coli and Coliform Analysis: Tests for coliform bacteria and Escherichia coli (E.coli) are the most important routine microbiological examinations carried out on drinking water. These tests provide a sensitive means for detecting faecal contamination, for assessing raw water quality, the effectiveness of water treatment and disinfection and for monitoring the quality of potable water in distribution.
- Enterococci are found in the faeces of human and warm-blooded animals. The presence of Enterococci in water is an indicator of faecal pollution and possible enteric pathogens.
Bacterial contamination may not be detected by taste, smell or sight. Floods, human or animal waste, like insects, rodents or animals entering a water supply can be a cause for bacteria. The UK maximum contaminant level for coliform bacteria as well as enterococci in tap water set by DWI/DEFRA is zero cfu/100ml.
Systems which should regularly be sampled for E.coli include: care homes (every 6 months), Healthcare premises (every 6 months), larger buildings operating to BS8558 (every 6 months), boreholes / wells / private springs (every 6 months), poultry / broiler farm drinking lines.
Arranging a laboratory test is easy and our service includes everything required to carry out this analysis.

(*The laboratory has been accredited by UKAS for coliform/E.coli, TVC/ACC, P.A., enterococci, legionella analysis of potable, process as well as water from spa & pool.)
Each order is shipped with 1x pre-paid return packaging; if you are planning on taking samples at different times/places and returning them separately, then please place separate orders.
Results: The report shows the test results in the appropriate measurement, like ppm, mg/l, cfu/100ml etc. For drinking water, these can be compared to the Drinking Water Guidelines set for the UK, a summary can be seen in our guide Understanding your test results. Results will be sent per Email to the Email address used to place the order.
Please note, that we do not provide interpretation of the test results.
Expiry: Water sample to be returned within 7 weeks of order date (unless otherwise agreed).
Please note:
- We require a full water sample to be able to perform the tests. Refunds will not be offered where minimum volume of the sample requirements are not met.
- Water samples should be taken the same day they are collected.
