Analisis Kandungan Mangan pada Air Sumur dan Keluhan Kesehatan pada Masyarakat di Sekitar Tempat Pembuangan Akhir Terjun Kecamatan Medan Marelan

Abstract

Water is a basic necessity for all living things, especially humans, so its quality must remain clean and free from pollution. One source of clean water that is widely used is groundwater from wells. However, groundwater is susceptible to pollution, one of which is by leachate from landfills that can contain heavy metals such as manganese, which have a negative impact on the environment and human health. This study aims to analyze the manganese (Mn) content in well water and health complaints in the community around the Terjun Landfill, Medan Marelan District. This study is analytical with a cross-sectional design. Well water samples were taken from 10 houses located <250 m from the Terjun Landfill and 28 respondents. The water sample testing method used an ICP-OES tool and the results obtained were three well water samples above the maximum levels set by the Minister of Health Regulation No. 2 of 2023 (0.1 mg/l), namely 1.250 mg/l, 0.786 mg/l, and 0.382 mg/l. There was no significant relationship between the distance of the well and the manganese content in the well water (p=0.129). A total of 89.3% (25 people) did not experience health complaints related to manganese exposure. Those who experienced complaints in the form of tremors were 7.1%, difficulty maintaining balance was 7.1%, muscle stiffness was 3.6% and all of them occurred infrequently. Based on the results of the analysis of the risk of manganese exposure to health, the RQ results for all respondents were still below 1, which means that exposure was still within safe limits and residents who consumed the water were not at risk of experiencing health problems. It is hoped that the community will not use well water as drinking water because there are manganese levels in all well water even though they have different concentrations.
