The response to the detection of coliforms in drinking water requires immediate action to investigate their origin and implement appropriate corrective action. This study, jointly supported by UKWIR and the Drinking Water Inspectorate (DWI), developed an approach for systematic investigation into the occurrence of coliforms and E.coli in water supplies. Water company procedures and reporting of incidents were reviewed for consistency of approach, and elements of good practice identified, This was developed into a procedure consisting of a sequence of steps, directed by a flow chart, with each step cross-referenced to a toolbox containing appropriate actions for each stage of the investigation. This allows water companies to respond in a timely and effective manner that is proportionate to the incident under investigation, whilst at the same time ensuring that public health is not compromised.
