Mangrove swamp forest is protecting national coastal areas from natural bcnomenoli such as tsunami. Many restoration programs were conducted to rehabilitate Tumpat mangrove swamp forest. However, less attention was given towards assessment 011 water quality and sedimentary nutrient of the ecosystem. The present stud\ was carried out to determine the water quality and sedimentary nutrient status at fumpat mangrove swamp forest in Kelantan Delta. A total of 15 water and sediment samples individually were collected from 5 different islands of the study area. Three sampling stations from each islands were collected randomly for water and sediment samples. In situ data measurement such as Dissolved Oxygen (DO), Conductivity, pH, Temperature, and Salinity were taken and ex situp arameters such as Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammoniacal Nitrogen (NH3N), Oil and Grease (OG), and Total Suspended Solid (TSS) were analyzed according to the APHA method using multiparameter (YSI 556), spectrophotometer (DRB 5000) and DO meter (HQ40 d). Five nutrients were tested for sedimentary nutrient status and among them Potassium (K), Calcium (Ca), and Magnesium (Mg) were tested according to Spectrophotometric Determination method using Atomic Absorption Spectrophotometer (AAS). Nitrogen (N) and Phosphorus (P) were analyzed according to Total Kjedahl and Bray 2 method using AAS. Water Quality Index (WQI) -ck as found 60.43 which fall under Class III according to the WQI value suggested by DOE of Malaysia which indicated the study area was slightly polluted. Among the islands, Pulau Bedal was found the most polluted island in Tumpat mangrove swamp forest. The range of the target nutrient values were 0.36-0.49%, 2.14-8.33mg/L, 34.25- 69.40mg/L, 66.71-1 04. 18mg/L, and 47.83-106.81mg/L for N, P, K, Ca, and Mg, respectively. Correlation analyses indicated that the sedimentary nutrient status of the present study were not dynamic because most of the nutrients were affected by OG pollution.
