| dc.description.abstract | Waste is increasing every day, increasing the volume of waste will greatly affect the burden on landfills. The existence of landfills often has the potential to cause environmental pollution such as groundwater pollution caused by leachate, which contains heavy metals, one of which is cadmium. Avoiding cadmium pollution in well water requires looking at several factors in the kinetic pattern of environmental pollution. This type of research is observational analytic using a cross sectional design. The population of this study were wells belonging to the community around Terjun Landfills is of total 218 wells, so the sample for this study was 64 samples. Data analysis used univariate, bivariate analysis with the pearson, independent t, and ANOVA test, and multivariate analysis with multiple linear regression tests. The results of the research showed that the highest level of cadmium in well water was 9.81 μg/l and the lowest level was 0.009 μg/l, where many as 4 people (6.3%) were exposed to Cadmium levels of 5 μg/l and many as 8 people (12 .5%) who were exposed to cadmium levels of 3 μg/l. There is a significant relationship between well distance (p=0.001), well depth (p=0.001), soil pH (p=0.001), soil porosity (p=0.001) and cadmium levels in well water; There were differences in well floor conditions (p=0.009), soil type (p=0.001), plant vegetation (p=0.006) and cadmium levels in well water. Independent variables that can significantly influence cadmium levels in well water are well distance, well depth, and soil type, where the most dominant variable that influences is well distance. A safe area to live in around Terjun Landfill is estimated to be > 800 meters from Terjun Landfill. Advice for the public is not to use well water as drinking water. For the Medan Marelan District, it is hoped that it can facilitate the community with a source of clean water and drinking water, and Medan City Environmental Services is expected to handle the management of Terjun Landfill. | en_US |
