Monitoring of Surface Water Quality in Train Development Activities Plan between Makasar and Parepare, South Sulawesi Indonesia

Abstract

Background and Objectives: The plan for the construction of the Makassar - Parepare railway line is the priority for the development of the land transportation mode in South Sulawesi. The development plan has received an environmental permit which was then continued with a monitoring study. Methodology: Descriptive analysis methods are then compared with quality standards based on South Sulawesi Governor Regulation No. 69 of 2010. Physical parameters with organoleptic and conductivity methods. Heavy metal parameters using the Atomic Absorption Spectrophotometry method. Aquatic biota parameters are based on the Shannon wiener diversity index. The Results: The measurement results of the pre-construction stage addressing parameters that exceed the quality standard are turbidity. Measuring the monitoring period I, all parameters still meet quality standards, except Total Dissolved Solids and Cadmium, while other parameters are not required. Measurement. Period II, at all measurement locations the parameters of Total Dissolved Solids, Total Suspended Solid, Chemical Oxygen Demand and Dissolved Oxygen exceed the quality standards of the Diversity Index (H') results of the pre-construction period with the value            (H') = 1.92, (D) = 66, (E) = -, mild pollution waters category.  Period 1 (H') = 0.24, (D) = 0.88, (E) = 0.35, the category of moderately polluted.   Period II (H') = 0.78, (D) = 0.22, (E) = 0.49, the category of moderately polluted waters. Conclusions: Monitoring results show an increase in surface water pollution from mild to moderate.
