  • 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).
    bacteria testing negative result

    Yellow Color: Positive Result (It is highly likely that potentially harmful bacteria were detected).
    bacteria testing postive result
  • 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.
  • WaterSafe WS-425B Lead / Pesticide Test Instructions:
  • The Watersafe Lead Test can detect dissolved lead at levels below the EPA Action level of 15 parts per billion (ppb). The Watersafe Pesticide Test detects two of the most common pesticides used in the US at or below the EPA Maximum Contaminant Level (atrazine - 3 ppb, and simazine - 4 ppb).
  • 1. Open Lead / Pesticide packet and take out all contents. The packet contains a test vial, a dropper pipette, two Watersafe test strips, and a desiccant (to be discarded).
  • 2. Using dropper, place exactly TWO dropper-fuls of water sample into test vial. To pick up the sample, tightly squeeze the bulb at the end of the dropper and place the open end into the water sample. Release the bulb to pick up the sample, then squeeze again to expel the sample into the vial.
  • 3. Swirl vial gently for several seconds. Place on a flat surface.
  • 4. Place both test strips into the test vial, with arrows pointing DOWN.
  • 5. Wait 10 minutes. Do not disturb strips or vial during this time. Blue lines will appear on the strips.
  • 6. Take the strips out of the vial and lay them on a flat surface with the arrows pointing to the LEFT. Read Results.

    If you only see the LEFT line (next to number 1), the test is negative) Negative: The LEFT line (next to number 1) is darker than the RIGHT line (next to number 2)
    negative pesticide test

    Positive: The RIGHT line (next to number 2) is darker than the LEFT line (next to number 1), or lines are equally dark (Both LEFT and RIGHT lines are equally dark)
    negative pesticide test
  • 7. Note: If no lines appear, or both lines are very light, the test did not run properly and the result is not valid. If a test strip shows a positive result, your water sample may contain lead or pesticides at a toxic level.
