Water Quality and Pollution Potential Studies: Impacts on Public Health and Ecosystems

Abstract

This research aims to analyze water quality and potential pollution loads and their impact on health. The research focuses on the pollution index, using a regression analysis to determine the relationships between potential pollutant loads and river water quality, as well as analyzing the impact of Pusur River pollution on the ecosystem and human health. The results show that pollutants in the Pusur River exceed the quality standard for the nitrate parameter in samples taken at Sudimoro and Cokro Villages, and for the fecal coliform parameter at all sample points. The potential pollutant load in the Pusur River from fecal coliform parameters is 1.514E+13 MPN/day from domestic sources and 9.958E+08 MPN/day from livestock sources, with an Rsquare value of 63.3. The presence of Cd and Cu in Pusur River water is safe for the ecosystem and the environment. The level of health risk based on the concentration value of the fecal coliform pathogen in Pusur River water is deemed unsafe for consumption, while the statistical limit value (410 MPN / 100 mL) according to the Indonesian Ministry of Health only the water quality at the sample points in Cokro Village (188 < 410 MPN / 100 mL) and Taji (214 < 410 MPN / mL) is safe for swimming. The results of this research can be used to improve decision-making strategies to improve water quality, especially in the Pusur River, which is used for recreational activities.
