The development of an area is indicated by an increase in the number of settlements. The activities of the UIN Yogyakarta campus have had an impact on the number of newcomers living temporarily and permanently around the campus. The negative impact is caused by the pollution of the Gajahwong River water from the disposal of domestic waste from the surrounding population. This study aims to examine the pollution of coli and Escherichia coli bacteria in the Gajahwong River fragment around the UIN campus in Yogyakarta. The research method was used in the form of field surveys and secondary data analysis of environmental monitoring results from the Yogyakarta Provincial Environment Office during the period of 2015 - 2019. The results showed that the number of stools and a total of coli bacteria were far above the quality standard. Both coli bacteria reach maximum conditions in 2019 and occur during the dry season
