Steiger and Richard Kessler Abstract An inventory of wells was conducted between February 1990 and April 1991 on St. John, U.S. Virgin Islands. Maps of well locations and tables of well-inventory data for 83 wells (34 are dug wells and 49 are drilled wells) are compiled in this report. The demand for freshwater on St. John has exceeded the supply because of the growth in population and tourism. Currently, the demand for water on St. John is met by desalinated seawater, rainfall collected in cisterns, and ground water. The well-inventory data provides a database to assist hydrologists, water managers, and planners in the development and full utilization of the ground-water resources of St. John. INTRODUCTION Freshwater is a scarce and expensive commodity in the U.S. Virgin Islands (USVI) (Gomez-Gomez and others, 1984). A variety of freshwater sources are used to meet demand for freshwater in St. John. Currently, desalinated seawater, rooftop-rainfall catchments, and ground water are the major sources of freshwater supply. The U.S. Virgin Islands Water and Power Authority (VIWAPA) is responsible for the supply and distribution of public water for the USVI. Because of increases in the population and tourism, the development of the water resources of the USVI is becoming more important for the future of St. John. In planning for long-term supply of water for the USVI, VIWAPA is considering all possible sources of water. Carefully planned ground-water development can be the key to an inexpensive water supply in the future. Purpose and Scope The U.S. Geological Survey (USGS) entered into a cooperative program with VIWAPA during 1990 to complete a well inventory of St. John, USVI. This report presents data for 83 wells, including locations, from the completed inventory conducted on St. John between February 1990 and April 1991. Of the 83 wells in this report, 34 are dug wells and 49 are drilled wells. Description of Study Area St. John is the smallest of the three principal islands (St. Croix, St. Thomas, and St. John) that make up the USVI (fig. 1). The island is approximately 9 miles long and 2 to 4 miles wide and has an area of 19 square Introduction 1 0> (D^ I (A O O pc 64°50' 18°24' 64"48' 64°46' 64°44' 64°42' 64*40' 64'38' 18'22' 18°20' CARIBBEA 4 MILES 01234 KILOMETERS St. Thomas St. John CARIBBEAN SEA St. Croix 0 10 20 30 KILOMETERS Figure 1. Location of St. John and area grids. miles. St. John is composed of a main eastward trending ridge with steep slopes to the north descending to the sea. In contrast, the south side of the ridge has several prominent spur ridges that extend southward (Cosner, 1972). About two-thirds of the island lies within the boundaries of the Virgin Islands National Park administered by the U.S. National Park Service (NPS). Acknowledgments The authors express their appreciation to the NPS on St. John and to the U.S. Virgin Islands Department of Planning and Natural Resources (VIDPNR), Division of Environmental Protection, for their assistance in helping to locate many of the wells on St. John. The cooperation of the many well and land owners who allowed access to their property and provided information about their wells is gratefully acknowledged. DATA PRESENTATION The locations and descriptions of 83 wells constructed before May 1991 on St. John are presented in this report. For ease in locating wells, St. John was divided into 11 grids (fig. 1). Each numbered grid block is presented as a separate figure in this report (figs. 2 through 12). Each grid represents a two-minute square section of the USGS 1982 photorevised, 7.5 minute series, topographic maps of St. John. Each figure is published at the original topographic map scale of 1:24,000. Some grids cover areas in which no wells exist. Figures with grids that have wells located on them are followed immediately by a table (tables 1 through 7) containing selected well data for each well in that grid. 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 constructed, measured depth of well, well casing diameter, type of well finish and finished interval, land-surface altitude at well site, depth to water below land-surface datum, date water level was measured, and yield of well. The well numbers used in tables 1 through 7 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 numbers apply only to wells located on the accompanying figure. An appendix at the back of this report shows other information for each well including subsurface lithologic descriptions (when available), and any special remarks about the well. Also included for each well is the site-identification number by which the well may be referenced in other USGS publications. This site- identification number conforms with the USGS Ground-Water Site Inventory classification scheme. Once this number is established for a well it does not change. Records of wells on St. John were compiled from the USGS historical files, VIDPNR files, previously published reports (Cosner, 1972; Robison and others, 1973; Ausherman, [1983]), and verbal reports of well locations. These records were used to locate well sites in the field. All the wells presented in this report have been verified and inventoried by USGS personnel. Lithologic information and information about the construction of the wells were taken from well-drillers' logs, when available. Wells that could be sounded with a weighted steel tape were measured for depth by Data Presentation 3 USGS personnel. 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. Land-surface elevations at the well site were estimated from USGS topographic maps. The contour interval of the topographic maps of St. John is generally 40 feet. However, twenty-foot intervals are shown where slopes are gentle. The accuracy of reporting land-surface elevations in this report is considered to be half of the contour interval used. Depth-to-water measurements were made by USGS personnel. Yields were reported by the driller or estimated by the well owner or well manager. Wells that were pumping and had in-line flow meters were measured for yield by USGS personnel. The type of well finish refers to the method used to complete the drilled well. A slotted finish refers to the narrow slots cut into the well casing to allow for the flow of water into the well. An open hole refers to the portion of the well where no casing has been installed. Generally, the well is left open when the hole has been drilled into bedrock and there is no need to protect the well from cave-ins. The finish interval is the depth below land surface where the casing has been slotted or the hole has not been cased.
