Tap Water Bacteria
Name: Agatha M.
I would like to test bottled and tap water for any bacteria
and I'm wondering what kind of bacteria will I find growing in the petri
dishes? I am doing this experiment with the student that I tutor. Thanks
for your help.
I hope you do not find ANY bacteria. As long as the bottle has not been
opened, it should be fairly bacteria-free. If you do find any, it should be
fairly innocuous species.
Let your student brows the water safety display of
the Virtual Museum of Bacteria
For your info is an annotated list of links on
bacterial contamination of water at

If it is chlorinated water not much will grow and of course you would need a
control petri dish group of sterile water. Millipore and a few other
companies sell a cheap water culture kit. You can also get simple tests
done free at your extension agency...a trip there is always interesting.
