unit commander responsibilities for ground forces water
- Sufficient quantities of safe water
- enforcement of water discipline
- inform troops about the dangers of consuming untreated water
- know the proper methods of disinfection for personal drinking water
engineering offcer responsibilities for ground forces water

- selecting sources of raw water
medical department responsibilities for ground forces water
- advise CO on water quality issues
- Assist engineers with Selection of water, surveying water system
- conduct routine Halogen and BACTI
All water Sources are unsafe until?
evaluated and approved by medical
what influences water choice?
- Quality
- Quantity
- Accessibility
what is usually the easiest and safest source of water for ground forces?
Public water supply
Acceptable water sources?
- public water
- surface water
- ground water
- commercial bottled water
Surface water:
- Quality may be a problem
- more contaminated than other sources
- large quantity
Ground water:
- existing wells and springs
- less contaminated than surface water
- hard to determine quantity
- must be 30 yard up gradient from known contaminant
ways to treat water in the field:
- straining
- chemical additive
- coagulation
- sedimentation
most common field water purification system
ROPU
Light medium tactical freshwater purification unit
- 3000 gallons an hour
- freshwater only
Light weight water purifier
- 125 gallons an hour
- mobile forward deployed
internal organization for standardization
- Moved with Palletized load system truck
- 1500 gallons per hour
- replacing the ROPU
most common Disinfection method in the field
Chlorine
if being transported what ppm must ground force water be?
1.0 ppm FAC
what ppm must water be if going into canteens or personal use containers?
0.2 ppm FAC
what ppm must ground water approved for drinking be?
2 ppm after 30 minute contact time
for natural surface water or well water under the influence of surface water what must the ppm be?
treated at 5ppm after 30 minute contact time
what water holding tank holds 3,000 gallons
3000 gallon onion tank
Load handing system water tank rack (HIPPO)
