Analysis of Well Water Quality in Ngofabubawa Village, Malifut District, North Halmahera Regency

Abstract

Well water is one of the sources of clean water that is widely used by people in rural areas. However, the quality of well water can be affected by various factors, so it is necessary to monitor and evaluate it periodically. This study aims to analyze the quality of well water in Ngofabubawa Village based on physical, chemical, and microbiological parameters, and compare it with previous research. The research methods used are field surveys and laboratory analysis. Well water samples were taken from 10 points in Ngofabubawa Village, then tested to determine the values of physical parameters (turbidity, color, odor), chemical (Fe), and microbiological (total E. coli). The results showed that the average level of turbidity of well water was 5.2 NTU, exceeding the set quality standards. The average iron (Fe) content is 0.8 mg/L, still below the quality standard. However, the total E. coli averaged 120 MPN/100mL, exceeding the permissible quality standards. There is an increase in microbiological contamination of well water in Ngofabubawa Village. This indicates the need for better sanitation and water treatment efforts to maintain well water quality and public health. Overall, the quality of well water in Ngofabubawa Village has not fully met the standard standards for clean water quality, so comprehensive management and improvement are needed
