## Water Resources: Hydrologic Data Tips

USGS conducts studies to analyze and interpret water-resources data for specific Federal requirements or to meet the needs of our governmental partners. However, most applications of data are the responsibility of users. USGS does provide some general tools, listed below, that may be useful for applying its water data. In some cases, other Federal agencies or our data partners have provided tools or documented procedures that may help to analyze, interpret, or apply USGS water data for particular applications.
Assessing the value of dams is a complex matter. Damming can serve many of society's needs, especially those of a thriving community or region. For example, water released from reservoirs that form upstream from a dam can be used to generate electricity. By smoothing out the natural, seasonal variation in water flow, dams also provide a reliable water supply to regional populations, help reduce the risk of floods and droughts, and provide recreational opportunities. However, there are also many reasons not to build dams.

## Water Conservation: Denver, CO

Global ground water supplies contain a greater volume of fresh water than all rivers, lakes, and wetlands combined. They provide most drinking water and most water used for agricultural irrigation. Ground water collects beneath the surface in permeable geological formations known as aquifers.

Daily water use is 69.3 gallons. Here is how it breaks down: Source: Residential End Uses of Water (Denver, Colo.: Water Research Foundation, 1999). By installing more efficient water fixtures and regularly checking for leaks, households can reduce water use by about 35% to about 45.2 gallons per day Here's how it breaks down for households using conservation measures: Source: Handbook of Water Use and Conservation , Amy Vickers

## Average Water Use Per Person Per Day

MÉXICO.- La falta de acceso a agua potable ha convertido a México en el país con mayor consumo per capita de agua embotellada, de acuerdo al último reporte de la Beverage Marketing Corporation (abril-mayo de 2010), el consumo por persona de agua embotellada llegó a 234 litros al año. El consumo per cápita es más del doble que los estadounidenses (110 litros) y se encuentra muy por encima del de España (119 litros). El consumo de agua en botellas en México representa el 13% de las ventas mundiales de agua embotellada, la que ha aumentado sin parar, con un crecimiento anual de 8.1%. Tan solo entre 2004 y 2009 este mercado creció 40%. Actualmente, la venta de agua embotellada asciende a 26,032 millones de litros al año, de los cuales se estima que 18,222 millones (70%) fueron comercializados en garrafón y 7,809 millones (30%) en botellas individuales, con todas las consecuencias que esto implica para la economía familiar y en particular para el medio ambiente.
