Analysis of water pollution index around gold mining in the downstream of Krueng Kluet sub-watershed

Abstract

Water is one of the primary needs of every living creature. With the increase in population, the need for water continues to increase. The declining water quality caused by human activities is one of the world’s concerns. This study examines river water quality status in the gold mining area in the downstream of Krueng Kluet sub-watershed. The method used to determine the level of river water pollution is based on the Decree of Minister of Environment Number 115 the Year 2003, which uses class 1 water quality standards according to Government Regulation of The Republic of Indonesia Number 82 the Year. The results show that river water in the study area is in the category that is not polluted or fulfills water quality standards for drinking water and daily needs.

Distribution of Mercury in Soil, Water, and Vegetable Fern in a Former Gold Mining Area – Evidence from Nagan Raya Regency, Aceh Province, Indonesia

Moreover, the illegal gold processing is commonly known for its action of discharging the wastewater to the river [Basri and Prayudi, 2022]. Nonetheless, in this present study, the presence of mercury was not detected in all sampling points (Table 4).…”
