This study’s main objective is to ascertain whether river samples taken from four separate locations in Malaysia’s Terengganu state are contaminated with heavy metals. All samples were dried at 80 °C for a full day in order to measure their moisture content. The range of the water content was 70-77%. To determine the content of heavy metals, triplicate samples were assessed using an Atomic Absorption Spectrophotometer (AAS). All solid samples were completely digested for three hours at 120 °C using an oven and Teflon beakers. Lead and zinc were discovered to be more prevalent in sediments than other elements. Additional factors include pH, BOD, COD, DO, LOI, TN, and TP. Total nitrogen and phosphorus concentrations are highest in samples taken from locations near farms and municipal locations. With the exception of a few instances where it surpassed the limit, the concentration was generally below the acceptable level limit established for the water and sediment rules.
