Consumption of contaminated water can result in various gastrointestinal problems and waterborne diseases. Environmental Health Practitioners are responsible for the monitoring and surveillance of water quality in order to verify safety for human consumption.

2. PURPOSE To ensure that appropriate water sampling procedures are carried out at Dr Harry Surtie Hospital. 3. APPLICATION This Standard Operating Procedure (SOP) applies to all persons responsible for collecting water samples at Dr Harry Surtie Hospital which may include but is not limited to: Environmental Health, Infection Prevention and Control, Quality Assurance. 4. LEGAL POLICY AND FRAMEWORK  Constitution of the Republic of South Africa 108 of 1996  Water Services Act 108 of 1997  National Environmental Management Act 107 of 1998  National Water Act 36 of 1998  National Health Act 61 of 2003  World Health Organization transcripts 5. PROCEDURE 5.1. PRECAUTIONARY MEASURES  Sampling containers and water sampling documentation to be collected from NICD laboratory on hospital premises

 Keep sampling containers sealed and in a clean condition until the point of use  Do not rinse the bottles with any water prior to sampling  Ensure samples are transported to the laboratory within the same day sampling was conducted 5.2. SAMPLING PROCEDURE

  1. Identify sampling points, collection of at least three samples from different locations within the hospital is recommended
  2. Clearly label sampling containers with location and reference number
  3. Fill out water sampling documentation with a description of where each sample was collected from.
  4. Turn the tap full on and allow the water to run to waste, 2 to 3 minutes is generally sufficient. This flushes the interior of the nozzle and discharges stagnant water
  5. Disinfect the tap using a surface disinfectant of at least 70% ethanol. A spray or wash bottle may be used to disinfect the outside of the tap and as much of the inside as possible. Wait 2 to 3 minutes for the solution to take effect before turning the tap on again.
  6. Fill sample containers to no more than 75%, allowing some room in the container.
  7. Samples to be dropped off at NICD laboratory on hospital premises within the same day of collection to be sent for testing..
