ED Decision 2025/007/R
POTABLE WATER TESTING, CHEMICAL SUBSTANCES AND GSE
(a) The GH organisation should ensure that regular tests are performed on the potable water at various water transfer points before it is uplifted into the aircraft potable water reservoir. Evidence of such tests should be kept in accordance with the documents and records requirements.
(b) The chemical composition of the water to be uplifted into the aircraft potable water reservoir should meet the standards set by the World Health Organization or the relevant state authority, whichever is more stringent.
(c) The potable water should be free from any unnecessary chemical substances and microorganisms. It may be treated with suitable disinfectants such as those based on chlorine or hydrogen peroxide. Ozone may also be present after further treatment, to provide additional disinfection and protection against microbiological contaminants.
(d) The potable water servicing equipment should be maintained in accordance with the GSE maintenance programme. The truck should be clearly identified as ‘drinking/potable water for aircraft’ and regularly cleaned and disinfected in accordance with the applicable standards. When not in use, the potable water truck should be parked in an area different from the one where other GSE with non‑potable water is parked.
(e) The GH organisation should apply any other additional instructions of the aircraft operator.
AMC1 GH.OPS.320 requires regular potable water testing, WHO or state standards, permitted disinfectants, proper GSE maintenance, clear truck identification, and separate parking from non-potable GSE.
