Abstract

The occurrence of
haloacetic acids (HAAs) was studied in the drinking water samples from Gharbiya
governorate water treatment plants and its water supply network that served
more than 5 million people. Drinking water disinfection by-products are formed
when a disinfectant reacts with natural organic matter and/or bromide/iodide
present in a raw water source. 
Trihalomethanes and haloacetic acids are the two most prevalent classes
of DBPs and are regulated by the US Environmental Protection Agency as well as
being subject to World Health Organization guidelines due to their potential
health risk. Drinking water samples were collected from 4 sites monthly over
one year (2017-2018). The aims of the present study are to investigate the
levels of HAAs in Gharbiya governorate (middle of Delta Egypt) drinking water. monochloroacetic
acid ranged from 6.8 to 32.5 µg/L, dichloroacetic acid ranged from 9.8 to 43.7
µg/L, and the trichloroacetic acid ranged from 6.5 to 31.8 µg/L, the minimum
values observed during winter 2018 and the maximum value observed during summer
2017., The HAAs species values were complying with the Egyptian standard
(Ministerial Decree No.458/2007) and as well as WHO 2012) standards for
drinking water.
