| 總結: | Springs that are found in Gunungkidul karst region is potential water resources
that can�t be ignored. Springs in this region have different character of quantity
and quality because of its specific morphology and lithology. A lot of resident in
arid region like Gunungkidul, are enact spring as one of fount to meet their needs.
So, it is necessary to do a study to know the character of quantity and quality of
springs in karst region at Gunungkidul, springs distribution, and its potential to
fulfill water needs of resident in the future.
Survey method is dominant in this research. Purposive sampling method used to
springs sampling which are taken to laboratory testing and respondent sampling
which are be interviewed. The research is descriptive and comparative.
Descriptive analysis is used to describe the condition and characteristic of
springs. Comparative analysis is used to compare and classify physical and
chemical feature of springs from the result of laboratory test. Projection is
performed to determine how long springs quantity can fulfill water needs.
At last, this research resulted that the springs in Panggang District are unevenly
distributed, 6 of 11 springs are located at Girisuko, and the others spreads in
Giriharjo, Giriwungu and Girikarto. Type of springs in Panggang District is
contact, emergence and exsurgence. In quantity, daily discharge reach out total
20,319.9 m3 that potentially can be able to fulfill Panggang District�s resident
water needs until 2028. In quality, water of springs dominate by high element of
calcium (Ca2+) (170 � 108 mg/L), magnesium (Mg2+) (5 � 53 mg/L), and hardness
(CaCO3) (200 � 435 mg/L). The height of the element (calcium, magnesium and
hardness) can be tolerated by treatments that is deposit its element before
consumed.
