Abstract

Groundwater is the world's primary source of drinking water. Unfortunately, we face the reality that access to safe drinking water is a worldwide issue nowadays. The presence of fluoride in groundwater is one of the causes of the fluorosis disease, which affects hundreds of millions of people around the world. Asembagus, an endemic area for fluorosis in Indonesia, requires updating its current risk status due to dynamically changing factors over time. Therefore, this research aims to estimate the probability of human health risk based on a population-at-risk calculation. Using an ion-selective electrode, we carefully tested 45 water samples from shallow groundwater in situ. The interpolation technique was used to determine the current potential risk zone and calculate the population at risk. The result showed that the fluoride concentration in the study area varied from 0.29 to 3.41 mg/L, with a mean of 1.22 mg/L. In Asembagus, the threat of skeletal fluorosis still affects 859 people (6.16%), and dental fluorosis affects 1,122 people (8.04%). Based on this study's findings, we concluded that the potential risk of non-carcinogenic fluorosis has significantly decreased since more than 20 years ago. This information is very useful for the government and public health authorities to further mitigate and protect people in the Asembagus area.

Abstract

Groundwater serves as the primary source of potable water globally, including in Indonesia. Unfortunately, the presence of fluoride concentrations in groundwater, whether in ideal, insufficient, or excessive quantities, can have either beneficial or detrimental effects. Presently, the inhabitants of Jakarta persist in relying on groundwater as their primary source of clean water, which presents an escalating peril to public well-being as a result of increased domestic activities. Regarding the situation, this research aims to analyze the temporal trends and spatial distribution of fluoride concentration in groundwater and its potential consequences for public health risks in Jakarta. A total of 1,418 fluoride and temperature data from the Jakarta Environmental Agency was used for spatial-temporal analysis of 2016–2019 trends. We applied Microsoft Excel 2021 and ArcGIS Pro 3.2 for statistical and spatial data analysis. The result indicated that the fluoride concentration in groundwater was 72.14% below the minimum recommended value of 0.5 mg/L, mostly in the southern part of Jakarta. However, the average fluoride concentration for all seasons per year is consistently increasing, specifically in the northern part of Jakarta. Based on this research's findings, we concluded that the deficiency of fluoride concentration in groundwater is the majority problem in Southern Jakarta and could potentially cause dental caries if the groundwater is used as the daily source of clean water. This information is very useful for the government and public health authorities to further mitigate and protect people in Jakarta who still rely on groundwater as the source of clean water.
