TM 5-6630-215-12 (d) Shake the jars slowly by inverting and returning to the upright position for 5 minutes. NOTE Keep bottles tightly capped. (e) Allow the jars to stand undisturbed. Note the setting rate of the floc and the clarity of the water above the flocculent layer. The sample that yields the fastest flock settling rate with clear water above the flocculent layer, contains the best coagulant concen- tration to be used for the water being treated. (f) Each drop of ferric chloride is equivalent to 10 ppm. (g) If, after 15 minutes, none of the jars have clear water above the flocculent layer, the test must be repeated. (h) Repeat step (a). (i) Repeat step (b), but add 5 drops of ferric chloride solut- ion to the first jar, 6 drops to the second, 7 drops to the third, and 8 drops to the fourth test jar. (j) Repeat step (c) thru (e). 2-23. REFILL KIT, CHEMICAL AGENT DETECTOR, V-G COMPONENTS (Used for Buys 1 and 2 Only, Fig. 2-23). The tickets and paper contained in this refill kit are designed to indicate whether V or G contaminants are present. V-G contaminants can affect the central nervous system. Their presence indicates pollution by toxic industrial wastes or agricultural pesticide, herbicide and fungicide residues. They have somewhat identical, persistent and nonpersistent, toxicity properties as chemical warfare agents. If the water is contaminated, then proceed with the proce- dures for the Water Testing Kit, Chemical Agents, AN-M2 (para 2-24). a. Contents (1) Belt of 40 plastic pockets. (2) Belt of 40 detector tickets. (3) Book of chemical agent detector, V-G-H paper. (4) Bottle of trihydroxymethylaminomethane (TRIS) (white lined). (5) Substrate solution dispenser (red dot on cap). b. Procedure for Water Contamination Determination. (1) Remove detector ticket from plastic package and save package. (2) Add 1 or 2 drops of suspected water to square end of the ticket by any convenient means, dropper, stirring rod, twig, etc., or by dipping the ticket into the water. 2-86 Change 1
