The history of water supplies is an interesting start to understanding the whole picture of the water issues we face today. Populations followed water supplies as exploration and expansion happened. But with the advent of water re-distribution systems, towns started popping up in places people never lived before. Those towns have become cities. Agriculture followed the same pattern as populations. Given that only about .008% of the world's water supplies are readily available andpotable, we'll all be in trouble if we don't take more care with our water supplies. Fresh water is necessary for life, and that is threatened by water pollution and water quality in general.
The history of water supplies in the United States begins with surface water -- lakes, ponds, rivers, and streams. Pioneers are opportunistic. Early exploration and settlement of the U. S. pretty much followed the natural occurrences of convenient water supplies. Shallow wells were dug only under circumstances that compelled settlement at sites where surface water was unavailable, ie, rich mineral deposits or unclaimed (presumably less desirable) farm and ranch land.
