DO-IT-YOURSE LF
BACTERIA IN WATER TEST
INSTRUCTIONS FOR DO-IT-YOURSELF BACTERIA IN DRINKING WATER
SAMPLING AND TESTING:
SAMPLE COLLECTION
Wash your hands before starting. Remove the
test vial with the white “tamper evident” cap.
Turn on cold water and allow it to run for
approximately five minutes before sampling.
Reduce the flow of water to about the diameter
of a pencil. Remove the white cap completely.
Tilt the vial slightly and slowly fill the vial to
the 25 mL mark near the top. Do not fill
past this mark. Do not overflow the vial.
Tightly screw the cap on the vial and shake well,
making sure that the media in the vial dissolves
completely. Set the vial in an upright position
and on a flat surface.
SAMPLE INCUBATION
Incubate your water sample at temperatures in
the following ranges (70°–105°F or 21°–40.6°C)
indoors or outdoors. A temperature of 95.5° F /
35.3° C is best.
Test results as fast as *24 hours (*speed of test
results may vary). Test results for bacteria will
take a minimum of 24 hours (± 4 hours) to
complete. Lower incubation temperatures
and/or lower bacteria numbers may cause
final results to take up to 72 hours.
Store vial in an upright position (out of direct
sunlight) until test’s result is evident.
Shaking the vial for 5–10 seconds (every 8–12
hours) can enhance color development but is
not required.

CONTENTS NEEDED FOR THIS TEST
IMPORTANT INFORMATION
DIY Test Media—Composition: a mixture of organic and
in-organic compounds. Ingredients include: Sodium Chloride,
Tryptose, Dipotassium Hydrogenorthophosphate, Potassium
dihydrogenorthophosphate, L-Tryptohan, D-Glucitol. Does not
contain any chemicals known to cause cancer, birth,or any
other reproductive defects.
Handling DIY Test Vial—Before use, contents of this
vial should be stored, tightly closed, dry, protected from light
and at a temperature between 59° F to 77° F (15° C to 25° C).
Keep away from strong oxidizing agents. Do not touch the
mouth of the vial or the inside of the cap. You will view the
test results in the comfort of your own home. Do not return
this DIY test vial to our laboratory. Once test is completed,
dispose of test vial and its contents as directed. Keep out

plenty of water and remove contaminated clothing. If test
media makes eye contact, rinse eyes out with plenty of water.
If test media is swallowed, drink water (two glasses at most).
Consult a doctor if feeling unwell.
TEST RESULTS
After proper incubation time has elapsed and
results are evident, without opening the vial,
observe the color of the liquid.
Yellow = Absent (negative result for
coliform bacteria). Coliform bacteria, including
E. coli bacteria are absent. Note: As long as the
sample inside the vial is clear or yellow, allow
incubation to continue for at least 72 hours,
to confirm the absence of bacteria.
Teal or Blue/Green = Present (positive
result for coliform bacteria). This test result
could include E. coli. Color and intensity may
vary. NOTE: If any shade of blue/green exists
at any time during the test period (between
24–72 hours), the test is complete.
When the test is complete, open vial and discard
liquid into toilet. Place a few drops of household
bleach into the vial, cap it, shake it, and once
again discard the contents into the toilet. Recap
the vial. Place the vial in a trash can. Wash your
hands thoroughly with soap and warm water.
The results of our
Safe Home® (DIY) Bacteria
in Water Test
are quite accurate. This test is
a “Presence/Absence” indicator of bacteria.
