Green and Gregory Cherry Abstract This report presents a compilation of well-inventory data collected from 634 wells between December 1988 and September 1990 for St. Croix, U.S. Virgin Islands. The report includes maps of well locations and tables of well-inventory data. The demand for freshwater in St. Croix is increasing, because of the growth in population and tourism. Currently, the demand for water in St. Croix is met by ground water, rainfall cisterns, and a desalination plant. The well-inventory data in this report provides a database to assist hydrologists, water managers, and planners in the development and full utilization of the ground-water resources of St. Croix. INTRODUCTION Freshwater is a scarce and expensive commodity in the U.S. Virgin Islands (USVI) (Gomez-Gomez and others, 1985). To meet the demand for freshwater on St. Croix, all available freshwater sources are used. In 1985, desalinated seawater provided about 66 percent of the freshwater supplies, and rooftop rainfall catchments and ground water provided about 9 and 25 percent of the freshwater supplies, respectively (Torres- Sierra, 1987). The U.S. Virgin Islands Department of Planning and Natural Resources (VIDPNR) is responsible for long- term planning and protection of the water resources of the USVI. Recent increases in population and tourism in St. Croix have placed increasing demands on the freshwater supplies. In planning for the long-term supply of water for the USVI, VIDPNR is considering all possible sources of freshwater. It is anticipated that carefully planned ground-water development is the key to an inexpensive water supply in the future, if ground- water contamination can be identified and controlled. To plan and develop these ground-water supplies, a database must be developed for the ground-water resources of St. Croix. Purpose and Scope The U.S. Geological Survey (USGS) entered into a cooperative program with VIDPNR during 1988 to complete a well inventory of St. Croix, USVI. This report presents data, including locations, for 634 wells from the completed inventory conducted in St. Croix between December 1988 and September 1990. Introduction 1 Description of Area St. Croix is the largest of the three principal islands (St. Croix, St. Thomas, and St. John) that comprise the U.S. Virgin Islands (fig. 1). St. Croix is characterized by a mountainous area in the north flanked by a rolling plain to the south (Rivera and others, 1979). The mountains are broken by many narrow, steep-sided valleys through which intermittent streams discharge in southerly and southeasterly courses across the plain. Few deeply cut streams flow directly westward. St. Croix is approximately 22 miles long, ranges from 1 to 6 miles wide, and has an area of approximately 84 square miles. DATA PRESENTATION The locations and descriptions of 634 wells located on St. Croix between December 1988 and September 1990 are presented in this report. For ease in locating wells, St. Croix was divided into 29 grids (fig. 1). All grids shown in figure 1 are presented as separate figures in this report (figures 2 through 30). Each grid represents a section of the USGS 1982 photorevised 7.5-minute series topographic maps of St. Croix. Each figure is published at the original topographic map scale of 1:24,000. Some grids cover areas in which no wells exist. Grids that have wells located on them are followed immediately by a table containing selected well data (tables 1 through 24). When available, information presented in these tables includes: well number as referenced on the preceding figure, well name, primary use of water, year the well was constructed, reported depth of well when drilled, measured depth of well, well casing diameter, type of well finish and finish interval, land-surface altitude at well site, depth to water below land-surface datum, date water level measured, and yield of well. The well numbers used in these tables (tables 1 through 24) consist of two parts. The first part refers to the grid number from figure 1, and the second part is a sequence number for the well within the grid. These well numbers apply only to this report. Wells mentioned in other reports can be identified by the site-identification numbers, which are presented in appendix A. The site-identification numbers (appendix A) conform with the established USGS Ground-Water Site Inventory classification scheme. The site-identification number does not change and can be used to reference a specific well in other USGS publications. Other information included in this report is the subsurface lithologic descriptions (when available) of a well and any special information about a well. The lithology at the well site and any special information are presented in appendix B. Records of wells in St. Croix were compiled from USGS historical files, files of VIDPNR, and files of the U.S. Virgin Islands Energy Office. These records were used to locate well sites in the field. All wells presented in this report have been field checked and inventoried by USGS personnel. When available, information about the construction of the wells was taken from well-drillers' logs. Wells that could be sounded with a weighted steel tape were measured for depth. Some of the information on well depths and type of well finish were provided by the well owner or were reported on previous well inventories. 2 Water wells on St. Croix, U.S. Virgin Islands I £ OJ- O-LO (0 g "i_ O) CO CD CO TJ C CO X 'O O c O' s O O I O)il Data Presentation The land-surface altitude of each well was estimated from USGS topographic maps. The contour interval of the topographic maps of St. Croix are 20 feet in the uplands and mountainous areas and 10 feet in coastal areas where the topographic gradient is low. The accuracy of reporting land-surface altitudes in this report is considered to be half of the contour interval used.
