Urban water resources



When Elbridge Gerry, a native son of Marblehead, Massachusetts, affixed a signature to the declaration of Independence, Boston had only about 16,000 inhabitants. Not only has Boston grown to over 40 times that size, but there are more peole in Metropolitan Boston now than there were in all thirteen colonies in 1776. Not only has our nation grown almost 100-fold in the past 200 years, but that growth has been increasingly urban. As may be seen in Figure 1, the United States became predominantly urban in 1920.
