Total 126 samples obtained result of positive turbidity laboratory test 49 samples (39%) and negative opacity 77 (61%), while the number of positive coliform bacteria 72 samples (57% ) and the number of negative coliform bacteria 54 samples (43%). Water quality can be concluded that 54 samples (43%) qualify microbiology and physics (turbidity), while 72 samples (57%) do not allowed microbiological requirements.
