The physical and chemical parameters of the water are critical for the life of aquatic biota. This study aimed to assess water quality in the Porong River estu-ary, Indonesia based on determining the physical and chemical parameters of the water, including the level of cadmium content, in the sediments and mollusks Corbula faba Hinds. This research was conducted in May – June 2019. The ob-tained results showed that the mean concentration of dissolved oxygen ranged from 8.7 to 14.2 mg/L, the mean temperature was 30.8–31.4°C, the salinity value was 9.0–30.6 ppt, and the pH value ranged from 7.80 to 8.46. It has been found that the Porong River estuary was slightly polluted, even though aquatic biota can still inhabit it. However, based on the atomic absorption spectrophotometry test, the mean values of cadmium content in the sediments and Corbula faba samples were 1.82 and 2.06 mg/kg, respectively. Based on the quality standards for sediments and aquatic biota, these mean values have exceeded the maximum threshold, indicating that the sediments and Corbula faba have been contami-nated with the heavy metal cadmium. © 2025 Begell House, Inc.
