The microbiology quality analysis of the waters of riuapa river and its impact on the environment

The Waeriuapa is the main river in the Wae Riuapa watershed which is widely used for agricultural irrigation, fishery cultivation ponds and domestic needs such as bathing and washing. As a flowing open-water ecosystem, the Riuapa river receives external disposals starting from upstream to downstream in the form of domestic waste, industrial waste, agricultural waste and from natural disasters such as erosion and landslides. The study conducted was to identify water quality by measuring the level of water pollution both in the river stream and on the river banks, specifically its microbiology quality. The results of the RALF analysis indicates the influence of the station location and season towards the levels of Total Coliform and E. coli bacteria in the river water and water wells that exceed the threshold of quality standards affecting the health of the surrounding environment. Changes in land cover on the WaeRiuapa watershed also influences the debit fluctuations in rainwater and dilution of pollutants, thereby reducing the river water quality with a total Coliform level of during wet season an average of 937.6 amount/ 100ml, during the dry season an average of 2,222.7 amount/ 100ml (BM Total Coliform: 3,000 amount/ 100ml), and E. coli at an average rainfall of 35.53amount/ 100ml, during dry season an average of 20.67 amount/ 100ml. | The microbiology quality analysis of the waters of riuapa river and its impact on the environment
