Abstract

The Cirasea River can provide water for both the Bandung basin and agricultural irrigation. Intensive agriculture, industry, and land use changes could have an impact on water quality. The purpose of this study is to look at the origins of heavy metals in riparian water resources. Heavy metal analysis was performed on 13 groundwater and river water samples. Heavy metals in water sources were compared with sediment and soil. The samples were analyzed for heavy metals using an AAS instrument. The research method employs statistical, geographical, and heavy metal pollution index (HPI). The HPI for river water was 131, whereas groundwater was 93. River water with an HPI value of more than 100 is highly polluted, indicating that it is unsafe for human consumption and has negative health consequences. Data verification with heavy metals in sediments reveals the presence of heavy metals coming from geogenic circumstances in various locations in the upstream area. Heavy metals in downstream areas result from geological factors and anthropogenic activities in the surrounding area. The long-term effects of heavy metal pollution along the riparian zone will become apparent. More research is needed on communities that depend on groundwater supplies along the Cirasea watershed.

Abstract

South Kalih and Panjang Islands are located in Banten Bay, small island with environmental conditions adjacent to the center of industrial activities. Industrial activities near the waters can increase the risk of heavy metal pollution, thereby affecting the quality of the aquatic environment. This study aims to evaluate the condition of aquatic environmental quality based on heavy metal content in sediments. Sediment sampling was conducted at ten observation stations using a purposive random sampling method. Heavy metal analysis was performed using the Flame Atomic Absorption Spectrometry (FAAS). The results indicate that South Kalih Island accumulated more Pb heavy metals with an average of 2.7922 mg kg⁻¹, while the highest accumulation of Cu heavy metals was on Panjang Island with an average of 5.7188 mg kg⁻¹. The accumulation of heavy metals Pb and Cu in the sediments in South Kalih and Panjang Island was below the standard threshold, except at PPS5P1 of Panjang Island, where Cu concentrations exceeded the CCME (2002) quality guideline. Areas with dense anthropogenic activities are more likely to increase the accumulation of heavy metals in the waters.
