The Edwards aquifer system is one of the great karstic aquifer
systems of the world. It supplies water for more than 2 million
people and for agricultural, municipal, industrial, and recreational uses.
The Edwards (Balcones Fault Zone) Aquifer in the San Antonio, Texas, area was
the fi rst to be designated a sole source aquifer by the Environmental Protection
Agency in 1975. The Edwards Aquifer also hosts unique groundwater, cave, and
spring ecosystems. This 27-chapter memoir reviews the current state of knowledge,
current and emerging challenges to wise use of the aquifer system, and some of the
technologies that must be adopted to address these challenges.
