This study focus on investigate seasonal variations
and relationships between water quality parameters and disinfection byproducts
(DBPs) within the Sakarya River where is located in Turkey. This river water is
rapidly endangered by urbanization, industrial and agricultural activities so,
to research pollution of river samples have been taken from 5 different points
along the river during one year. Within this scope, changes in the dissolved
organic carbon (DOC), biological oxygen demand (BOD5), chemical oxygen demand
(COD), ultraviolet absorbance at 254 nm (UV254), specific ultraviolet
absorbance (SUVA254), trihalomethane formation potential (THMFP), and
haloacetic acids formation potential (HAAFP) are measured. High coefficient of
determination (R2) was 0.64 and 0.62 UV between THMFP and HAAFP respectively,
also THMFP and HAAFP relationships between UV254 (R2) was found to be close to
each other. COD, BOD and NBOM maximum coefficient of determination between DBPs
was 0,62. High correlation coefficients (r) of 0.80 and 0.79 between SUVA254 and
DBPs were obtained for THMFP and HAAFP respectively. The reactivity of the
organic matter changed throughout the year; with the lowest reactivity for both
THMFP and HAAFP in fall, increasing in spring and reaching a maximum in summer
season. Understanding the seasonal changes and corelations between organic
matter and their reactivity should lead to a better optimization of the
treatment method and a more consistent water quality.
