WATER TESTING KIT, CHEMICAL AGENTS (Used for Buys 1 and 2 Only)
(fig.
2-24).
This kit is designed to determine the toxicological
characteristics of drinking water.
It is a reconnaissance field kit
for water testing and screening raw water sources so contaminated with
chemical agents that they cannot be rendered potable with customary
field Lyster Bag filtering or similar treatment.
A preliminary screening
using the chemical agents detector procedure (para 2-23) should be made
prior to these tests to indicate whether the water is contaminated.
