Monitoring Number Of Colifom and Escherichia Coli on Drinking Water Refill as Pollution Bioindicator

Abstract

One of the very needed natural resources on our planet is water. A total of 70% of the Earth's surface is water utilized for human development such as drinking, irrigation and cultivating fish. Contaminated water will have a bad effect on all living creatures and their environment [7]. Sources of water pollution can be derived from manusi stool containing coliform bacteria. The research purposes will be monitoring colifom number and Escherichia coli on some samples of drinking water as a bioindicator of drinking water pollution considering the higher the population consuming drinking water refill. This resource is pure resource experiment that use design of resource descriptive analitic. The data obtained will be displayed in the frequency distribution table to see the figure of coliform and E.coli in refill drinking water. From the results of this study, of 20 samples of drinking water refill there were 14 unqualified samples where the coliform figures exceeded quality standards. And 5 positive samples of E. Coli bacteria

Evaluation of Refillable Drinking Water Quality Based on MPN Coliform and Escherichia Coli Insesetan Village, South Denpasar, Bali

“…However, due to the diversity and complexity of human requirements, the water demand, particularly for drinking water, has increased (Ahmed et al, 2020). However, water availability, pure water, and water fit for human use are concerns (Amallia, 2020). As a result, a portion of the community relies on replenished drinking water to satisfy their daily drinking water needs (Pulungan and Away, 2019;String et al, 2021).…”

“…Agustina (2021) reported five samples of raw water from Semarang City's refill drinking water depots were positively contaminated with Coliform bacteria with Most Probable Number (MPN) values, including Candisari District (20/100 ml), Tembalang District (7/100 ml), Ngaliyan District (11/100 ml), West Semarang District (4/100 ml), and Gunung Pati District (4/100 ml), and two samples were not. Furthermore, Amallia (2020) discovered that 14 out of 20 samples of replenished drinking water did not satisfy the criteria, with the quantity of Coliform exceeding the quality level and five samples positive for the bacteria Escherichia coli. This situation demonstrates that Indonesian refilled drinking water quality is still poor and unfit for human consumption.…”
