Study of Water Quality and Heavy Metals in Several Locations in Rivers and Estuaries of Lurang Village, North Wetar, Southwest Maluku, Indonesia

Abstract

Water plays an important role in life and is a vital component that supports biodiversity and secures the existence of ecosystems. Water sampling in this study consisted of 13 stations, namely 10 stations in river waters and 3 stations in estuary areas in the waters of Lurang Village, North Wetar District, Southwest Maluku Regency, Indonesia. The water quality parameter measurement results show that the water quality conditions in several locations are below the optimum limit. Heavy metal test samples were taken from 4 locations, namely RW35, RW36, RW39 and RWBG.Ds to be tested for the metal content of Selenium (Se), Cadmium (Cd), Copper (Cu), Lead (Pb) and Mercury (Hg). The presence of heavy metals in waters is a result of pollution from industrial, agricultural and other waste products. This study aims to determine the water quality and distribution of heavy metals in the river and estuary waters in Lurang Village, North Wetar District, West Maluku Regency.
