Study of dug well water quality in Labuan Bajo, Indonesia

Abstract

The dug well water quality in community settlements needs assessment to ensure its quality. The water has to meet the required physical, chemical, and bacteriological standards. This initial research aimed to determine the dug well water quality in Kampung Ujung, Komodo District, Labuan Bajo City, WestManggarai Regency in September 2019. The research method was used survey and laboratory. The two dug well was taken used a purposive sampling technique. The test parameters include temperature, turbidity, pH, smell, Total Suspended Solid (TSS), sulfate, Total Dissolved Solid (TDS), nitrate, nitrite, Total Hardness, Dissolved Oxygen (DO), nitrogen ammonia, total coliforms, and Escherichia coli. The analysis physically, chemically, and biologically of two dug well water samples were had done examined. The result showed that the parameters of TDS, nitrate, nitrite, E. coli, and DO exceed the Class I Water Quality Standard. The research concluded that the quality of both dug well water in the Kampung Ujung Labuan Bajo area was not suitable for use as material raw drinking water. Furthermore, the government should provide other water sources such as the addition of storage tanks for raw water, so that people do not entirely depend on dug well water.

Filter Series Model for Processing Well Water into Drinking Water in the Milala Residential Area, Central House of Pancurbatu District

“…It shows the pollution of shallow water in the Kampung Ujung area. This research concluded that the quality of the to dug wells in the Kampung Ujung Labuan Bajo area is not appropriate for use as rawmaterial for drinking water (Wolo et al, 2020).…”

Climate Change Impact on Groundwater-Based Livelihood in Soan River Basin of Pakistan (South Asia) Based on the Perception of Local Farmers

“…To assess the people's perception of climate change and adaptation needs, a qualitative and quantitative questionnaire-based survey was carried out during the southwest monsoon season in India; the results revealed that the perceptions and the information gathered were the same as analyzed observed trends of climate data [50]. People's perception of climate variability (which includes heat, winter and summer temperature, reduced rainfall, and fewer floods) can be used to motivate people for some adaptations and mitigation measures, as an assessment of climate variability from the last 5 to 10 years in Bangladesh showed negative impacts in terms of agriculture, human lifestyle, and water resources of that region [24,[51][52][53][54][55][56]. Another questionnaire-based survey that observed climate change and people's perception of climate change was based on four variables: income, politics, agriculture, and economy in Montana.…”

Bacteriological quality and environment risk of water pollution of dug wells on Semau Island, Indonesia

“…The results of another study showed that the quality of two dug well water samples in Kampung Ujung The Labuan Bajo area is no longer suitable for use as raw material for drinking water. Furthermore, the government must provide other water sources such as: addition of raw water storage tanks, so that the community does not depend completely in dug well water (Wolo et al, 2020). Sanitation and hygiene in water sources are significantly related to the presence of E. coli in household drinking water (Ondieki et al, 2022).…”

“…Research in Kermansyah showed that Fecal coliform was found in water sources in urban (22%) and rural (45%) (Davoodi et al, 2018) . Preliminary research on dug well water in Labuan Bajo showed that the E. coli parameters exceeded the requirements (Wolo et al, 2020) . A water inspection study using the MPN (Most Probable Number) method which consists of 3 tests, namely, a presumption test, a confirmatory test, and a reinforcing test showed that from 15 drinking water samples 8 samples of drinking water were tested positive for Coliform bacteria contamination, while 7 other samples were negative.…”
