Check for the presence of coliform bacteria in your drinking water with this do-it-yourself, EPA-based test kit.
InformationContaminated water may not smell or taste bad, but the presence of even small amounts of some kinds of bacteria can cause anything from upset stomachs to hospital visits. Some waterborne bacteria can even be deadly! Don't risk it for your family. Test your water for harmful bacteria with our simple do-it-yourself kit.
Contains one EPA-based Coliform Bacteria* test for your home tap water, detailed instructions and comparison table.
*The presence of bacteria in drinking water is usually the result of a problem with your region's water-treatment plant or private well. A positive result indicates that your water may be contaminated with bacteria that can be harmful to your health or cause disease.
Bacteria Test Instructions:
1. Take out the Bacteria Test vial and set upright on a flat surface.
2. Collect water sample or turn on tap to a very slow stream.
3. Carefully twist off cap and fill vial to 1/2 inch below the top (to 5 ml line).
DO NOT OVERFILL and DO NOT SPILL the bacterial growth powder in the vial.
4. Replace cap and twist on tightly. Shake the vial vigorously for 20 seconds.
5. Place the capped vial upright in a warm area (70-90 F) where it cannot be disturbed for 48 hrs.
6. After 48 hrs., observe the color of the liquid without opening the vial:
Purple color: Negative Result (No bacteria were detected).
Yellow Color: Positive Result (It is highly likely that potentially harmful bacteria were detected).
7. For positive results, add bleach to the sample before pouring down the toilet, then wash hands carefully. Negative samples may be poured directly into the toilet. Discard vial in the trash.
