Distribution of Physico-Chemical Parameters of Coastal Waters in Palopo, Indonesia
The population growth and lack of public awareness toward the environment affect the growth of waste disposal, which results in environmental pollution. This research aims to clarify the quality of coastal waters based on physico-chemical parameters. Water samples were taken in wet and dry monsoons in 18 stations, and physicochemical parameter analyses were conducted in the field and laboratory. The pollution distribution pattern was analyzed using the Surfer 13 software. The result showed that in the wet monsoon, the temperature was 30 oC – 33°C, turbidity 3.4 – 40.45 NTU, salinity 27 ‰ – 38‰, pH 6.55 - 7.21, DO 3.41 – 4.90 mg. L-1, BOD 1.76 – 4.41 mg. L-1, TSS 37 – 88.6 mg. L –1, and TDS 1.430 – 2.430 mg. L-1. In the dry monsoon, the temperature was 27 – 31oC, turbidity 2.03 – 48.12 NTU, salinity 18 ‰ – 37‰, pH 7.28 – 7.89, DO 1.55 – 6.79 mg. L-1, BOD 0.29 – 0.91 mg. L-1, TSS 28.10 -66.49 mg. L -1, and TDS 1.460 – 3.170 mg. L-1. Wet and dry monsoons affect the distribution of the physico-chemical parameters of coastal waters.
