Potable Water Testing

Potable Water & Fresh Water Testing

Ships usually have only one system, a freshwater generator, on board that converts seawater to Potable water using desalination, reverse osmosis, and UV treatment. Potable water is used for drinking, cooking, dishwashing. Fresh water for laundering, sanitary purposes, washing up, bathing etc. Sometimes, ships are bunkered with water from various sources, such as directly from the port, by water tankers, bottled water, or ice bars.

What are the current regulations?

Water standards vary from country to country, but all countries have a minimum standard that drinking water must meet. Preliminary testing of the following characteristics of water periodically is important: pH, chlorides, Organic and Inorganic chemicals, E. coli, HPC & Legionella,
ILO Convention: Ships must provide enough quantities of water for drinking, food preparation, cooking, dishwashing, and personal hygiene purposes.
Maritime Labour Convention (MLC) 2006:Ensures that seafarers have access to good quality drinking water.
EU 2020/2184 OF THE EC: The Drinking Water Directive ensures high-quality drinking water by updating safety standards, identifying, and managing quality risks, and monitoring emerging substances.

Bacterial testing

offshore labs can provide a complete package of potable water testing, presence of bacteria, such as E. coli, coliforms HPC. ETE.Coli- linked to ice-cooled drinks and tap water.

Viral testing

Offshore lab test detects the presence of viruses, such as norovirus and rotavirus. Enhance the periodical testing improves seafarer health.

Chemical testing

Offshore Lab based test detects the presence of chemicals, such as lead, mercury, and arsenic Etc.

CHANCE FOR CONTAMINATION

Contaminated water from land or Port water bunkering.
Cross-connections between Potable and non-Potable pipeline.
Poorly designed storage tanks.
Biofilm production on water lines, clogged or oxidized pipes, and improper storage and cleaning cycles.
Inadequate disinfection: According to ISO standard Seawater desalinated below 80°C must be disinfected to be potable.
Swallowing these harmful pollutants by mistake pose a health risk for shipping crew.
