Are latrines located at least 100 yards (91 M) downstream or down gradient from water sources or purification
operations?
Are the latrines properly constructed and maintained?
Are hand-washing devices supplied with soap and water?
Are garbage and trash properly stored and disposed of at least 100 feet from water point operations?
Has a check been made to see that no pollution sources exist in the immediate surrounding area upstream or up gradient
from the water point?
Have water purification personnel conducted tests for chemical agents and radioactivity?
PART I - MONITORING WATER QUALITY REQUIREMENTS
Monitoring Water Quality. Water quality is of two major concerns for you. First, what is the quality of the raw water and
its effect on equipment and the chemicals used in treatment? Second what is the finished product water quality, and what are
the results of the tests used to measure potability after the water passes through the water purification system?
The nature of the raw water source determines the amount of water each purifier can produce. The total-daily water
requirement indicates if additional water purification and storage equipment is needed to meet the demand. You are to
monitor chemical analyses and microbiological examinations of raw and treated water which are conducted on a routine basis
at water point sites. You will do this by having water purification personnel provide you with the appropriate forms, such as
DA Form 1713-R (Figs. 1-6 and 1-7). Chemical tests are necessary to ensure correct operation of the water purification
equipment. During treatment have personnel conduct chemical analyses to ensure proper chemical dosages are being used
and that the product water is potable. After treatment have personnel draw samples for Preventive Medicine to conduct
microbiological tests to determine potability of the water. Preventive medicine personnel are also required to inspect water
points. When performing the tests, personnel will use the Water Quality Analysis Unit.
Using Water Quality Analysis Unit. Ensure that your water treatment operators use the Water Quality Analysis Unit. It
gives them the ability to rapidly detect five water quality parameters: temperature, pH, TDS, turbidity, and free available
chlorine (chlorine residual).
The Water Quality Analysis Unit consists of an electronic analytical device, an internal power source, basic spare parts,
and the M272 Water Testing Kit-Chemical Agent. The Water Quality Analysis Unit weighs less than 40 pounds, has a
volume of less than 2 cubic feet, and requires less than five minutes to measure the five separate parameters.
The Water Quality Analysis Unit can operate in geographical areas where air temperatures range from -28€ to 120F. It
is used mainly by water purification personnel who operate DS and GS water purification equipment. Water purification
personnel use the unit during water-point reconnaissance missions to assess
