Field water quality standards
Emergency - Answer- Select clearest, cleanest, least odorous water and treat with
iodine, chlorine ampoules, boiling
Field water quality standards
Short term consumption - Answer- 7 consecutive days or less which prevent acces to
potable water
Field water quality standards
Long term consumption - Answer- More than 7 days when treated water is produced by
water purification units
Water quality standards at fixed instalion
Army - Answer- TB MED 576
Water quality standards at fixed instal
Navy - Answer- NAVMED P-5010-5
National Primary Drinking Water Regulations - Answer- Federally enforced legislation
that affects potability
National Secondary Drinking Water Regulations - Answer- Guidelines that affect the
aesthetic quality of water, state law, locally enforced
Types of disinfectants
Iodine - Answer- Individual use
Types of disinfectants
Chlor-floc - Answer- Individual use that combines chlorine compound with flocculating
agent and works best with dirty water
Types of disinfectants
Chlorine - Answer- Chlorine gas: 100 percent
Calcium hypochlorite: 70 percent
Sodium hypochlorite: 5 percent
, Chlorine dose - Answer- The amount of chlorine applied to a given amount of water.
Chlorine demand - Answer- The difference between the amounts of chlorine added to
water and the amount of residual chlorine remaining at the end of a specified contact
period.
Chlorine Residual - Answer- amount of chlorine left in the water after the chlorine
demand has taken effect
Factors affecting chlorine residual - Answer- pH: can slow down chlorination
Temp (cold slow down, hot heats up, 70 is best)
Type of microorganism
Contact time ( 30 minutes)
Other interfering substances
