Unit 6.13 Potable Water Surveillence Flashcards
Who manages the potable water surveillance program?
IDC
Coaming
A raised frame (as around a hatchway in the deck of a ship) to keep out water
Distillation
The total process the distilling plant forms, including evaporation and condensation
Free Available Chlorine (FAC)
Chlorine available (after demand is met) in the forms of Hypochlorous acid and Hypochlorite ions
Micron
A unit of length. One millionth of a meter
Point of Use (POU)
A treatment device applied to a single tap used for the purpose of reducing contaminants in drinking water at that tap
Potable Water
Water that is suitable for human consumption, bathing, laundry, personal hygiene.
Reverse Osmosis (RO)
The reverse of the natural osmosis achieved by external application of sufficient reverse pressure to cause the solvent to flow in its unnatural direction
Colilert / Colisure
Test used to detect total coliform and E. coli in the potable water
Total Coliform
- Are a group of closely related, mostly harmless bacteria that live in soil and water as well as the guts of animals
- The extent to which total coliforms are present in the source water can indicate the general likelihood that the water is contaminated with fecal matter
- The presence or absence of total coliform bacteria is the drinking water standard.
E. Coli
- A type of fecal coliform bacteria commonly found in the intestines of animals and humans
- E. coli is short for Escherichia coli
- The presence of E. coli inin water is a strong indication of recentsewageor animal contamination
- Sewage may contain many types of disease-causing organisms
Naval Sea Systems Command (NAVSEASYSCOM)
- Responsible for the shipboard potable water systems, including treatment facilities and processes to assure that safe drinking water is available at all times.
- – Design
- – Construction
- – Maintenance
Naval Facilities Engineering Command (NAVFACENGCOM)
Responsible for promulgating instructions for ship-to-shore potable water connections and for providing potable water from an approved source when the ship is berthed at a naval facility
Chief, BUMED
- Responsible for establishing and promulgating health standards for water quality afloat
- Promulgate appropriate instructions, notices, or other publications to reflect afloat water quality requirements
- Establish the shipboard requirements for medical surveillance of potable water systems.
Area, Fleet and Subordinate Commanders
Responsible for issuing the necessary implementing directives to ensure that adequate water sanitation standards are provided and enforced in each ship within the command
Commanding Officers
- Responsible for promulgating a water sanitation bill to ensure procedures are followed for:
- – Receipt
- – Transfer
- – Treatment
- – Storage and distribution
- – Surveillance
Engineering Department
- Supply and treatment of Potable water
- Potable water system components that:
- – Receive
- – Store
- – Distribute
- – Produce
- – Treat
- Ensure that all ship-to-shore and ship-to-ship connections are made only by authorized personnel, when available, or in their absence, ship personnel who are properly supervised by authorized personnel
- Halogen and pH testing
- Ensure minimum halogen residuals are maintained at a potable water tank before placing the tank on-line to the potable water distribution system
Medical Department Representative (MDR)
- Responsible for conducting a medical surveillance program of the potable water system including collection of water samples for:
- – Bacteriological (BACTI) Testing
- – Daily Halogen Testing
- MDR shall notify the Commanding Officer of any discrepancies observed in the potable water distribution system
DESCRIBE minimum usage requirements for potable water afloat
- New Ship Construction
- 50 Gallons per man per day is specifiedby NAVSEASYSCOM for design considerations
- Does not apply to “Water Hours”
- – No less than 2 gallons/man/day
