This is polygon data of shallowest principal aquifers of Puerto Rico and the United States Virgin Islands, developed as part of the effort to produce a map published at , in Chapter HA N of the "Ground Water Atlas of the United States" series of printed publications. See Other_Citation_Details for publication h Year: This dataset, published in , contains the shallowest principal aquifers of the conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, portrayed as polygons. The map layer was developed as part of the effort to produce the maps published at ,, in the printed series Ground Water Atlas of the United States. Fresh ground-water withdrawals from alluvial aquifers throughout Puerto Rico during were about 24 million gallons per day, or nearly 14 percent of the total ground water withdrawn on the island. Withdrawals from the alluvial valley aquifer in the Humacao-Naguabo area were million gallons per day during If these maps do not address the location in question, refer to the USGS , maps titled Unconsolidated Aquifers in Upstate New York (leaves DEC website).. Areas shown as "Unconfined Aquifer 10 to gallons per minute" or "Unconfined Aquifer more than gallons per minute" are considered to be Principal Aquifers unless contradictory site specific information is made available to .
This map layer contains the shallowest principal aquifers of the state of Florida portrayed as polygons. The map layer was developed as part of the effort to produce the series "Ground Water Atlas of the United States". The published maps contain base and cultural features not included in these data. This is a replacement for the July map layer called Principal Aquifers of the Plate 1.

Estimated potentiometric surface of the upper aquifer, North Coast limestone aquifer system (average conditions between and ) : Robert A. Renken, Fernando Gómez-Gómez. Introduction. The north coast karst aquifer (Figure 1), which comprises 19% of the island, is the most extensive and productive fresh-water aquifer in Puerto Rico (Lugo et. al, ; Veve and Taggart, ).This aquifer serves as a significant source of water for domestic, industrial, and agricultural uses ().Groundwater in the region also discharges to surface water features, contributing Cited by: In its latest report on water use in the United States, the USGS looked at the nation's dependence on ground water. The report entitled Estimated Withdrawals from Principal Aquifers in the United States, , provides details of ground-water withdrawals and use from principal aquifers in .
During rainfall events, the aquifers in Puerto Rico capture a small fraction of the rainfall and sometimes can store it for years. Organic pollutants are degraded over time by microbial and chemical processes. The shorter the travel time between raindrop and aquifer recharge the greater is the risk of contamination. Existing data from non-pumping observation wells have been used to identify Cited by: 1. () Hydrogeology of the Principal Aquifers in Vigo and Clay Counties, Indiana. Interpretive report by L. W.

The pattern of lithofacies within this basin appears to have been controlled by changes in base level that were, at times, dominated by tectonic movement (uplift and.
