The Maritime Labour Convention (MLC 2006) sets out minimum standards to ensure the health, safety, and welfare of seafarers around the world. One of the lesser-known but vital aspects of compliance is potable water testing — a requirement that directly impacts onboard health and the operational standing of a vessel.

As a Cyprus-based laboratory specializing in maritime services, Cypriot company Maritime Lab offers MLC-compliant potable water testing that covers both microbiological and chemical parameters — helping shipowners and managers meet international obligations efficiently.

 

Why Is Potable Water Testing Required?

 

Poor water quality can result in gastrointestinal illnesses, spread of bacteria, and diminished crew performance. To avoid this, MLC 2006 mandates that drinking water be safe, regularly tested, and stored under hygienic conditions.

 

Failure to meet this standard may result in:

  • Fines or detainment during port state inspections

  • Legal claims from crew

  • Negative audit findings during ISM reviews

What Should Be Tested?

At a minimum, water samples are analyzed for:

Microbiological Parameters:

  • Escherichia coli (E. coli)

  • Total Coliforms

  • Legionella

  • Pseudomonas aeruginosa

Chemical Parameters:

  • pH, turbidity, and conductivity

  • Heavy metals (lead, copper)

  • Chlorine levels

  • Hardness and alkalinity
