Potable water is water that is safe enough to be consumed by humans and other animals and is also known as drinking water.

The routine microbiological and chemical analysis of potable water samples ensures that the water quality provided in municipal buildings such as hospitals and care homes is safe to be consumed.  20/30 Labs are UKAS accredited to test potable water samples in accordance with the Microbiology of Drinking Water published by the Environment Agency and The Water Supply Water Quality (England and Wales) Regulations 2000 SI No 3184 published by the Drinking Water Inspectorate.  The Approved Code of Practice, The Control of Legionella Bacteria in Water Systems (ACOP L8, HSG Parts 1, 2 & 3) published by the HSE is used for the surveillance of Legionella in water.

Total Viable Counts (TVCs) by Pour Plate

The test for Total Viable Count (TVC) is used to determine the presence of microbiological contamination in potable water samples.  The test identifies the presence of mesophyllic gram-negative and gram-positive organisms.

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.

Enterococcus--enterococci-water-testing

Enterococci Analysis

Enterococci are facultative anaerobic organisms that are part of the normal intestinal flora of humans and animals.  Their presence in potable water is indicative of waste contamination of the water supply.

Legionella Analysis

There is a duty of care in the UK to perform routine analysis of water samples for the presence of Legionella, a group of organisms that cause pneumonia like illnesses particularly in those that are elderly or immunocompromised.  Read more

Legionella-Potable-Water-Testing

Sulphate Reducing Bacteria*

Sulphate reducing bacteria are a group of organisms that produce hydrogen sulphide in anaerobic conditions.  The hydrogen sulphide taints the water with an odour of rotten eggs and can cause corrosion within the potable water transport system.

Pseudomonas Aeruginosa Analysis

Pseudomonas bacteria are common opportunistic pathogens that can thrive in potable water systems and when in contact with immune compromised patients can cause a variety of illnesses. Pseudomonas should therefore not be present in the water systems of places that have regular human contact, such as hospitals and swimming pools. Organisations have a legal obligation to assess the risks from Pseudomonas that may affect their staff or the public, take the appropriate preventative measures and ensure the measures are effective.
