Safety and palatability of drinking water supplies is of primary importance in Maritime and other industry sectors. Argentic’s new self- test kits allow operators and inspectors to test and confirm that water chlorination is to the appropriate recommended concentration.
‘Shore mains water often contains only a very low concentration of free chlorine and the ship environment decreases this further. In some countries there may be no free chlorine content at all. It is therefore recommended that all freshwater taken from shore or water barge should be chlorinated on loading to a sufficient concentration to ensure a residual free chlorine content of 0.2 ppm) The concentration may be checked by means of a commercial comparator kit. A regular routine for the chlorination of freshwater tanks to maintain 0.2 ppm concentration should be established.'( UK MCA Marine Guidance Note MGN 397).
In order to ensure these concentrations are achieved and maintained the following actions are recommended –
A 2005 collaborative study by the Association Of Port Health Authorities (APHA) and the Health Protection Agency (HPA) found 49% of the 950 potable water samples taken contained less than the regulatory minimum chlorine concentration (0.2 mg/l). Regular testing and correct chlorination of potable water tanks and outlets for chlorine will prevent growth of bacteria such as coliforms and e.coli, reducing risks and helping ensure employee health.
