Abstract :
The lecture activities at Diponegoro University in Tembalang resulted in a
rapid increase in population density in the Tembalang region and resulted in an
increase in waste generated. This condition affects the pollution of well water as
clean water. Most residents around Diponegoro University still use well water to
meet their daily needs, so there is a possibility that water in this area is polluted.
This study aims to determine the quality of water as raw drinking water, well
water testing is carried out using the petrifilm method.
This type of research is a literature study, this study uses secondary data
collection taken from previous research scientific journals. The data analysis
technique used is descriptive analysis method. Collaboration from 3 reference
journals of total coliforms of well water around Diponegoro University showed
that 100% of well water samples were polluted by coliform bacteria with the
number of bacteria exceeding the quality standards set by the Republic of
Indonesia Minister of Health Regulation Number 32 / Menkes / Per / 2017, so it
can be concluded that well water is not suitable for use as raw drinking water.
Some factors that are thought to influence the high number of coliform bacteria
include the distance of the septic tank with the well, livestock waste and the dense
population.
