Total Suspended Solids (TSS) Spatial Distribution of Manganese in Resident Well Impacted by Residential Activity: A Case Study of Medokan Ayu District-Surabaya

TSS (Total Suspended Solid) is an optical turbidity parameter to assess water quality and provide essential information for the water environment. Particularly, the degradation of watersheds creates immense pressure on water quality, especially in arid and semiarid regions. However, concentrations of TTS in water are also due to the effects of pollution, and activities on the surface. Therefore, factual information regarding determining the effective depth of TSS is essential for the estimation of the water column. To address this problem, we collected 100 water samples from 10 different sites of the wells at Medokan Ayu District, Surabaya (Indonesia). To investigate the TSS concentrations. The results showed that the quality of well water for the turbidity parameter did not exceed the standard of clean water quality, where the highest value was found in well 7: 17.97 NTU, for the Manganese parameter in wells that exceeded the quality standard, it was found in Well 2: 1.4 mg/L. , well 5: 1.7 mg/L, well 6: 1.8 mg/L, well 7 : 8.6 mg/L and well 9: 4.3 mg/L. Well TSS parameters that exceed quality standards are found at Well 1: 1,200 mg/L, Well 3: 1,200 mg/L, Well 5: 800 mg/L, Well 6: 1,600 mg/L, Well 7: 1,600 mg/L, Well 8 : 1,200 mg/L, Well 9 : 1,200 mg/L, and Well 10 : 1,200 mg/L. The pattern of distribution of pollution levels using surfer software mapping, three wells have the highest concentrations of Manganese, TSS, and Turbidity found in wells number 6, 7, and 9
