J. of GEOMATE.The existence of humic substances in peat water impacts the presence of the dissolved organic matter (DOM) which is the precursor of trihalomethanes (THMs) and haloacetic acids (HAAs). However, information on DOM characteristics, THMs and HAAs Formation Potential (THMFP and HAAFP) in tropical peat water are still limited. This study aimed to determine the correlations between DOM, THMFP, and HAAFP during dry and rainy seasons in tropical peat water in Indonesia. Samples of peat water are taken from the water canal and tidally affected river on Sumatera’s peatland during the rainy season and dry season to determine the effects of the seasons and tides. DOM measured by dissolved organic carbon (DOC), specific ultraviolet absorbance and the ratio of E465/E665 while THMFP determined from a total of THMFP4 measurements and HAAFP determined from measurement of total HAAFP5. Compared to dry season, values of all organic parameters on rainy season were higher but fewer in river. Canal water has a higher DOC while river water has a higher chloride and bromide content. Increasing of DOC in the rainy season correlates with increasing of THMFP4 and HAAFP5. THMFP4 is dominated by chloroform on canal while brominated THMs predominate in river water which correlates with the presence of bromide. Chlorinated HAAs dominate HAAFP5 in canal water while brominated HAAs increases in the river. Seasons and tides affect the appearance of bromide contaminants in water that affects the form of THMFP and HAAFP.[/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][/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 research work was funded by The Indonesia Endowment Fund for Education (Lembaga Pengelola Dana Pendidikan/LPDP), Ministry of Finance Indonesia.[/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.21660/2020.66.9487[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
