J. of GEOMATE.Dissolved Organic Matter (DOM) in water sources is reactive to chlorine, forming Trihalomethanes (THMs). However, information on DOM characteristics and Trihalomethanes Forming Potential (THMFP) in tropical surface raw water sources is still limited. This study aimed to determine the characteristics of Total Organic Matter (TOM) and DOM, the correlations between the pair, as well as the correlations between DOM and THMFP during dry and rainy seasons in a polluted tropical river in Indonesia. Samples were collected from Cikapundung River, at the intake of drinking water treatment plant during both seasons. TOM and DOM were measured as COD, DOC, Chromophoric organic (A254, A355, A3/4) and Specific Ultra Violet Absorbance (SUVA). Total THMFP (TTHMFP) was determined from CHCl3, CHBrCl2, CHClBr2, and CHBr3 measurements. Compared to the rainy seasons, the values of all organic parameters at the intake during the dry season were higher. DOM in the dry season was more aromatic, hydrophobic and humic, consistent with higher concentrations of TTHMFP in the dry season (X =636.79μg/L) than that in the rainy season (X =430.13μg/L). TOM and DOM correlations for A254, A355, and COD in the dry season were stronger than in the rainy season. Each THMFP species was poorly correlated with any DOM parameters during the dry season, specifically at SUVA level ≥ 5L/mg/m. However, there were significant correlations between A254 and CHBrCl2-FP; A355 and CHCl3-FP; A355 and TTHMFP. These conditions were observed only during the rainy seasons at SUVA of 2-4L/mg/m. Thus, A355 can be used as a proxy of TTHMFP during the rainy season in Cikapundung river.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Correlation,DOM characteristics,Seasonal variations,THMFP[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This study was funded by Riset Kelompok Keahlian Unggulan Grant in 2017 from LPPM ITB.
