Here is a city government bureaucrat who is very pleased by the great labor and expense that the City of New York goes to to ensure that the city drinking water is safe. Every single day, workers drive out to water sampling stations across the city, and do 900 water sample tests. That's all very fine and good; but mightn't there be some business or technology that could do the 900 water sample tests every day (and maybe even many more) much more quickly, efficiently, and (more importantly) cheaply? See if you can propose a better solution than sending government officials driving through NY traffic every day to collect water samples...
