Gunung Kidul Regency is an area that has a karst ecosystem known as Karst Gunungsewu. The landscape caused
this land to struggle with water scarcity due to its barren surface. One of the water recharge areas here is known
as the Sumurup River. The river is called the allogenic recharge of Karst Gunungsewu. This river that passes
through the settlement area and the city’s center has a bigger contamination potential due to its lack of filtration
process by soil and rock, unlike non-karst areas. This research was conducted by taking samples in the field and
then measuring its quality, followed by comparing the result to the Special Region of Yogyakarta Government
Regulation No. 20 Year 2008, then scoring it with Storage and Retrieval (STORET) method. The result is that
there has been pollution in Sumurup River by a concentration of phosphate parameters at 2.58 mg/l at location
A-2. The highest sulfate parameter was 27 mg/l at A-4 location. The highest nitrate parameter was 18.4 mg/l at
location A-2. The highest chloride parameter was 32.4 mg/l at monitoring point A-1. The highest count for total
coliform was 16×109 MPN/100 ml at location A-2. In addition, The STORET score indicates that the quality
status of all points is moderately polluted.
