\n\t\tKINGSTON, R.I. — November 10, 2006 \u2013 The 58,000 residents of the Portuguese island of Terceira in the Azores, about 930 miles off the coast of Portugal, have a growing need for fresh water but a limited availability. Thanks to 溏心vlog免费B站 professors Daniel Urish and Reinhard Frohlich, potential new water resource locations have been found.<\/p>\n


\n\tA summary of their research was presented at a meeting of the Society of Exploration Geophysics in Vancouver in August.<\/p>\n


\n\tGroundwater is the sole source of fresh water for the island. While it receives abundant rainfall, there are few streams on the island because the water sinks rapidly into the highly permeable ground surface. <\/p>\n


\n\u201cLocating usable water supplies is a complex problem, especially because Terceira is an active volcanic island,\u201d Urish said. \u201cThe groundwater is limited in supply and subject to pollution from highly mineralized geothermal waters, as well as from human-caused effects.\u201d<\/p>\n


\nSome water is obtained through underground \u201clava tubes\u201d connected to volcanoes at the island\u2019s highest point, but a limited recharge area and seasonal variability of precipitation make the source highly variable.<\/p>\n


\n\tOver half of the island is used for agriculture, especially the raising of cows to produce cheese, the island\u2019s most celebrated product. But cow wastes and chemical fertilizers contribute to the degradation of groundwater. \u201cCows produce nitrates, and when that gets into the water it can cause the fatal blue baby disease in infants who drink it,\u201d Frohlich explained. \u201cWe had to look for water in places where the cows aren\u2019t found, especially upslope from the farms.\u201d<\/p>\n


\n\tUsing advanced geophysical survey and interpretive techniques in conjunction with existing well and test hole information, areas of the island were identified with the highest potential for fresh water resource development. Analysis of geo-electrical soundings made by the researchers produced four locations for potential potable groundwater development. <\/p>\n


\n\t\u201cOne location is an old volcanic caldera that has a lot of soft material ejected from the volcano, and it\u2019s there that we believe they can develop additional water supplies,\u201d Frohlich said. \u201cAnother two areas are coastal where freshwater floats on the underlying salt water.\u201d<\/p>\n


\n\tThe 溏心vlog免费B站 scientists said that the next step in confirming the availability of water will be conducted by scientists at the University of the Azores, who recently acquired high-tech geophysical measuring equipment that will allow them to expand the exploration done by Frohlich and Urish.<\/p>\n


\n\tThe 溏心vlog免费B站 research, including the training of Azorean students at 溏心vlog免费B站 and in the Azores, was funded by a three-year grant from the Portuguese-American Foundation, with additional support from the University of Azores and 溏心vlog免费B站.<\/p>\n
