Quick Answer
For field use, chlorine drops should be added to water in a well-ventilated area, and the water should be stirred well to distribute the chlorine evenly. The recommended concentration is 2 drops per quart (1 liter) of water, and this should be checked regularly to ensure the water is safe to drink. A chlorine test kit is essential for monitoring the chlorine level.
Measuring and Adding Chlorine Drops
When using chlorine drops in the field, it’s crucial to measure the correct amount accurately. A typical chlorine drop bottle contains 1.5% available chlorine, which means 1 drop contains 0.015 grams of chlorine. To calculate the correct amount, multiply the desired chlorine concentration in milligrams per liter (mg/L) by the volume of water in liters. For example, to achieve 2 mg/L of chlorine in 1 liter of water, add 0.002 grams of chlorine, which is equivalent to 0.133 drops.
Storing and Handling Chlorine Drops
Store chlorine drops in a cool, dry place, away from direct sunlight and heat sources. Keep the bottle tightly sealed when not in use to prevent leakage and contamination. When handling chlorine drops, wear gloves and protective eyewear to prevent skin and eye irritation. Always add chlorine drops to water slowly and in small increments to avoid over-chlorination.
Monitoring Chlorine Levels
Regularly test the water for chlorine levels using a chlorine test kit. The recommended chlorine concentration for drinking water is 1-2 mg/L. If the chlorine level is too low, add more drops according to the manufacturer’s instructions. If the level is too high, wait 30 minutes to allow the chlorine to dissipate before re-testing.
