Excerpt from Recommended Minimum Water Well Construction and Sealing Standards for the Protection of Ground Water Quality, Alameda County Ground water basins are of vital importance to the economy of Alameda County. They are not only sources of readily available water but are major storage facilities. It is estimated that ground water basins supply water to more than wells in the county. Although a considerable number of these wells are used only for the irrigation of lawns and gardens and are of shallow depth and small capacity, many industries and municipalities depend on ground water for their water supply. Further, irrigated agriculture depends almost entirely on ground water. Numerous farm and home wells in Alameda County have been abandoned in recent years to make way for the phenomenal expansion of industrial and urban development. At the same time, new wells have been constructed to meet the increased demands for water. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
