Addendum: I left out the filtration and calibration steps required in the 'high-tech' approach to bacterial quantification, and I forget the name of the machine used to measure light absorption and emission at various wavelengths...bu' ith on th' tiph ah ma tongue! :) It wasn't even necessary for the usual sterile techniques (i.e. autoclaving) to be used with the waste sludge - just accurate dilutions with tap water (spot checks to ensure that sewage wasn't in the tap water probably weren't even necessary - unless there'd been a hurricane).
Your thoughts tonight really seem to be concentrated in the sewer . . .
