Stakeholder - ALS Environmental

Lister Hospital Project

All hospitals are required to monitor water which is supplied to their patients to ensure that the contents are free from harmful bacteria and organisms such as Legionella, E-coli, Coliforms and Pseudomonas.


A recent project conducted by Lakeside Water analysed over 50 sample points at Lister Hospital in 2011. This was done once a month in order to monitor for the presence of Microbiological organisms and, if required, cleanse and retest the water systems to ensure public safety.

The samples were transported to ALS Environmental using our dedicated, refrigerated transport service to ensure that the samples arrived at our Coventry laboratory at ambient conditions in line with sample stability. This ensures that the analysis reported is accredited to UKAS 17025:2005 to give additional confidence in the data provided.

Analytical Testing Requirements:

Based on their reputation and expertise for dealing with significant microbiological projects, ALS Environmental were selected by Lakeside to undertake the analysis of samples from Lister Hospital. The analysis undertaken consisted of:

  • Legionella
  • TVC 22°C
  • TVC 37°C
  • E-coli
  • Coliforms
  • Pseudomonas Aeurginosa
  • Pseudomonas Species

The Micro Notification system utilised by ALS automatically notified Lakeside of any high counts or presumed positives for Legionella. The data was also reported on the electronic dataview system allowing Lakeside to monitor the results online and take action as required.

We had potential water quality problem due to the actions of a third party and needed samples taken as a matter of urgency. Although this was outside the strict terms of our contract with ALS they were able to provide a sampler on a Friday afternoon, get the samples taken and returned to their labs for analysis.

They backed this excellent performance up by emailing us the sample results over the weekend. All in all a great piece of customer service!
