AH yes, those were the days - burned agar, boiled over flasks, chocolate agar
that is not chocolate enough. It was a good background, but I'm glad it's
behind me now. Too bad the new kids don't make media and clean glassware
anymore.
Anyway, I used to test potable water from drilled wells. We used the Standard
Methods manual for any procedures. We started with the MPN and I really hated
that. We then went to the filter method, drawing 100cc through a gridded filter
(.2 or .4 micron - I can't remember). Then we placed the filter onto fresh
Levine EMB and counted "green sheen" colonies as coliforms.
