This study aims to examine the impact of wastewater discharge from white shrimp farms on water and soil quality in Thung Krabue Subdistrict, Yan Ta Khao District, Trang Province, between December and January 2024. Samples were randomly collected from the shrimp pond wastewater outlet, with water and soil quality monitored monthly. The study measured pH levels, soil color, soil cohesion, soil fertility (NPK), dissolved oxygen in water, water temperature, water salinity, and nitrate concentration in water. The results showed that the average water temperature during shrimp farming was 24.5 ±0.7°C, and during wastewater discharge, it was 26.33°C. The pH during farming averaged 7.52 ±1, while during discharge, it was 8.49 ±1, both within acceptable limits for coastal aquaculture (Department of Fisheries, 2007). Dissolved oxygen levels during farming averaged 4.25 ±0.35 mg/L, while during discharge, they dropped to 2.58 ±0.35 mg/L. Nitrate levels during farming averaged 10 mg/L, increasing to 11.67 ±0.07 mg/L during discharge. Soil quality analysis at a depth of 5 cm in areas affected by wastewater showed an average temperature of 27.29°C, a pH of 6.61 ±0.2, and salinity of 10 ±0.9 ppt. Nutrient content (NPK) revealed nitrogen at 52.92 ±10.26 mg/L, phosphorus at 53.63 ±15.98 mg/L, and potassium at 183.67 ±38.07 mg/L, higher than at a depth of 10 cm due to prolonged exposure to wastewater. The discharge of water from white shrimp farms affects nearby water and soil quality, which may impact the local ecosystem and agricultural land use.
