5-Tube Coliform Water Test Powder Kit for Drinking Water, Wells, Ponds and Streams

This coliform test powder kit contains 5 pre-filled plastic tubes for testing water samples from drinking water sources, wells, ponds, and streams. Testing is simple: add 3mL of a water sample to a tube, wait 24 hours, and observe the color change. A yellow result indicates the presence of coliform bacteria, while purple indicates none detected. For disposal, add household bleach to the tube, shake for 30 seconds, and pour contents down the drain. The kit includes instructions and a safety data sheet. Manufactured in the United States.
