The hydrologic sciences continue to grow in importance as issues of drought, population growth and pollution, and politics come together to raise water issues to new levels. While groundwater hydrology plays a central role in the hydrologic sciences, relatively few comprehensive textbooks cover this field.
Between 1959 and 1979, Ground Water Hydrology (D.K.Todd) guided students and professionals. In 1979, Groundwater, (R.A. Freeze and J.A. Cherry) integrated geology and hydrology physics and chemistry and science and engineering. That text was followed in 1980 by Applied Hydrogeology (C.W. Fetter). Addressing a need for a new textbook, Physical and Chemical Hydrogeology (P.A. Domenico and F.W. Schwartz) was published in 1990.
