Abstract: Auhah Island is one of the most important islands in Kuwait for its role in facilitating the fishing industry. It is located 4 kilometers southeast of Failaka Island and occupies an area of 34 Km2 with no permanent residents unlike Failaka Island, which is the only populated island. Sharp rocks, especially in the northwest portion and blocks of hard material, dominate the topography of Auhah Island. The water and sediments of the island are important elements that facilitate the biodiversity of the area. Therefore, the current study aimed to investigate the water and sediment quality of Auhah Island with a view to determine its biodiversity. In order to accomplish this objective, ten water samples and ten sediment samples were collected from different locations around the island and analyzed for different physio-chemical and geochemical parameters, as well as inorganic nutrients, total petroleum hydrocarbons, total organic carbons, trace metals, and COD and BOD. The results of the study show that most of the physical characteristics of the study area such as dissolved oxygen, pH, and salinity are not supportive of biodiversity. The average dissolved oxygen levels of 0.345 ppm are an indication of a severely polluted environment. In terms of pH, the recorded range of 8.12-8.37 mol/L in water may not support certain marine organisms that require lesser pH. Similarly, the recorded average salinity of 45.39 ppm is above the acceptable maximum limit of 42 ppm. However, inorganic nutrients such as ammonia, nitrites, and nitrates are present in favorable concentrations except phosphates, which are present in high concentrations. The results of inorganic nutrients generally indicate that the study area has similar concentrations to those recorded in the large area of Kuwait Bay. The area of study also does not have toxic levels of TPH’s, TOC’s, and trace metals. However, the COD and BOD levels in sediments are very high which poses an environmental concern due to the pollution by organic compounds.
