| Abstract | Water-use data were aggregated for the 78 municipios of the Commonwealth of Puerto Rico for 2010. Five major offstream categories were considered: public-supply water withdrawals and deliveries, domestic and industrial self-supplied water use, crop-irrigation water use, and thermoelectric-power freshwater use. One instream wateruse category also was compiled: power-generation instream water use (thermoelectric saline withdrawals and hydroelectric power). Freshwater withdrawals for offstream use from surface-water [606 million gallons per day (Mgal/d)] and groundwater (118 Mgal/d) sources in Puerto Rico were estimated at 724 million gallons per day. The largest amount of freshwater withdrawn was by public-supply water facilities estimated at 677 Mgal/d. Public-supply domestic water use was estimated at 206 Mgal/d. Fresh groundwater withdrawals by domestic self-supplied users were estimated at 2.41 Mgal/d. Industrial self-supplied withdrawals were estimated at 4.30 Mgal/d. Withdrawals for crop irrigation purposes were estimated at 38.2 Mgal/d, or approximately 5 percent of all offstream freshwater withdrawals. Instream freshwater withdrawals by hydroelectric facilities were estimated at 556 Mgal/d and saline instream surface-water withdrawals for cooling purposes by thermoelectric-power facilities was estimated at 2,262 Mgal/d. Introduction The National Water-Use Information Program of the U.S. Geological Survey (USGS) is a cooperative program designed to compile, store, and disseminate water-use information locally and nationwide. Since 1950, the USGS has compiled data at 5-year intervals on amounts of water used in homes, businesses, and on farms in the United States, and has described how that use has changed with time. The program was implemented in Puerto Rico in 1980 to provide data for the management of the Commonwealth’s water resources. Water-use data reports by “municipios” were published for 1980–82 (Torres and Avilés, 1986), 1986–87 (Molina and Dopazo, 1995), for 1988–89 Estimated Water Use in Puerto Rico, 2010 By Wanda L. Molina-Rivera (Dopazo and Molina, 1995), for 1995, 2000 (Molina, 1998, 2005) and for 2005 (Molina and Gómez, 2008). Water-resources planners and managers must have information regarding the amount of water used, and where and how it is used, to adequately assess many of the critical water problems facing Puerto Rico. The USGS maintains cooperative agreements with the Puerto Rico Aqueduct and Sewer Authority (PRASA), the Puerto Rico Department of Natural and Environmental Resources (PRDNER), and the Puerto Rico Environmental Quality Board (PREQB). A compilation of water-use data for major use categories is an important requirement to assist water-resources managers and planners in Puerto Rico. Purpose and Scope The purpose of this report is to document wateruse data estimates in Puerto Rico for 2010. Estimated water use was determined for the following categories: (1) surface-water and groundwater withdrawals and their deliveries by public-supply facilities, (2) domestic use from public-supply water and self-supplied (3) groundwater withdrawals by industrial self-supplied users, (4) surfacewater and groundwater withdrawals for crop irrigation, and (5) groundwater withdrawals and public-supply deliveries for thermoelectric-power use. In addition, instream wateruse and saline withdrawals were estimated for hydroelectricpower generation and for cooling purposes at thermoelectric powerplants. Estimated water use was aggregated by municipios and sources of water for most of the water-use categories presented in this report. Public-supply water deliveries were categorized by ward (“barrios”), estimating the population served by individual public-supply water system. The location and geographic distribution of the 78 municipios of Puerto Rico are shown in figure 1. 2 Estimated Water Use in Puerto Rico, 2010 Fi gu re 1 .
