(b) Strontium-90: ten uuc/i.
(2) When the above concentrations are exceeded. the water supply may be
approved by the appropriate surgeon when a radiological survey shows that the intake
from all sources (primariIy food and water) does not exceed:
Radium--226: 20 uuc/day.
Strontium--90: 200 uuc/day.
(3) In the known absence of Strontium-90 and alpha emitters, the water
supply is acceptable when the gross beta concentrations do not exceed 1,000 uuc/i.
Gross beta concentrations in excess of 1,000 uuc/l are grounds for rejection of the
supply except where a complete analysis indicates that the exposures in (2), above, wiII
not be exceeded.
FIELD WATER SUPPLY STANDARDS
Physical and chemical standards for field water supplies fall into three categories:
a. Emergency, Short-Term Consumption. These standards, agreed to in both
STANAG 2136 and SOLOG Agreement 125, are mandatory for all NATO forces under
combat or similar conditions for a period not to exceed 7 days (see Table 4-4).
b. Emergency, Long-Term Consumption. These standards, agreed upon in
SOLOG 125, are preferable in water for consumption by troops under combat or similar
conditions for periods in excess of 7 days (see Table 4-4).
c. Routine Consumption. For rear areas, fixed installations, and other
situations, which may be clearly distinguished from combat conditions or similar
emergency, the concentrations of chemical substances in miIitary water supplies should
not exceed the values shown for fixed installations in Table 4-4. If local conditions or
short term requirements necessitate the use of water containing higher chemical
concentrations, the commander concerned should authorize such use only upon the
recommendation of his surgeon.
Section II. PHYSICAL AND CHEMICAL TESTS
The preventive medicine specialist must be able to properly collect water
samples for chemical analysis, properly complete DD Form 710 (Physical and Chemical
Analysis of Water), and properly measure the pH and chlorine residual of a water
sample. In addition, depending upon the type of unit to which he is assigned and the
type of equipment available, he may be required to conduct tests for poisons and other
impurities in water. Most detailed analyses of drinking water are conducted by the
