The influence of the acid water of the Banyupait River on the community health in Bantal village, Asembagus, Indonesia

Abstract

The pH of Mount Ijen crater water is 0-2, resulting in water that is acidic and sulfurous. A fault near the Mount Ijen Crater causes seepage so that acidic water flows into the Banyupait River. Chemical elements and heavy metals originating from the river pollute groundwater and plants. As a result, people around the river consume heavy metals. This research aims to determine the quality of river water and groundwater, as well as determine community factors that are susceptible to dental fluorosis. The methodology used is field mapping and laboratory analysis. For water samples, the Atomic Absorption Spectrophotometer (AAS) method is used. The pH of river water at the research location exceeds the quality standard, namely pH 4-5.5. Meanwhile, groundwater fluorine and sulfate elements exceed quality standards, namely fluorine of 0.6171 mg/L and 0.6870 mg/L, and sulfate ranging from 325-683 mg/L. These two elements cause symptoms of dental fluorosis. Meanwhile, the community factors most susceptible to dental fluorosis are people in the adult age category, and the last level of education is elementary school. This is because the Banyupait River water and groundwater are exposed to fluorine and sulfate water originating from seepage from the Mount Ijen Crater. HIGHLIGHTS Mount Ijen crater water exhibits extreme acidity, containing sulfurous compounds, leading to the acidification of the Banyupait River.; Pollution of groundwater and plants occurs at the Banyupait River, posing health risks to nearby communities.; Groundwater quality parameters, notably fluorine and sulfate levels are identified as contributors to dental fluorosis symptoms.;
