Pumps' Perplexities

"OK men, lets mount up and ride to the river in order
to protect our rights to the water.....Them varmints
ain't goin' to use it for their cattle".......

Water, the basic sustenance of mankind, has always
been a worrisome issue......In this modern time it
involves "purity".......People want to drink the purist
of water.....But the Global Warming folks are telling
us that shipping or trucking water from one place
to another is no good for the Earth.......Drinking it out
of a plastic bottle is no good for the Earth.......

I have come to the conclusion that if, #1 it takes
good; #2 does not smell or have a strange color;
#3 has not killed your neighbor......Then it is good
enough to drink.......Let's face when did the word
"water filtration" enter into common usage?......
