Description
According to the U.S. Geological Survey, an estimated 258 million people
nationwide, or 86% of the U.S. population, relied on public water supplies
for their household use in 2005 (USGS, 2013). The remaining population
obtains their water from different sources, such as a domestic self-supply
well. However, the spatial distribution of water supply systems has not been
compiled. Mapping where these people are located can be done within a GIS
(Geographic Information System). The approach used takes into account a
number of different attributes gathered from the United States Census Bureau
for the block group and block shapes within the Delaware River Basin.
