Water is the basic need of life. Chlorination is a well-known disinfection technique for potable water due to its cheap availability. Yet, some aspects are harmful to human health and found carcinogenic. An attempt has been made to quantify the occurrence of two prominent Chlorination Disinfectant byproducts (DBPs), i.e., Trihalomethanes (THMs) and Trihalo acetic acids (THAAs) in the water distribution network of galvanized iron Pipes Medium using GC-Mass Spectrometry equipped with Electron Capture Detector (ECD). Two filtration setups, i.e., Granular Activated Carbon (GAC) and a pack of sand, were evaluated as abatement techniques were introduced for removing these chlorination disinfectants by products according to the water source and pipe medium used. The chromatogram with mass spectrometry hints at the occurrence of these two DBPs and the filtration media’s characterization and removal capacity. A combination of granulated activated carbon accompanied with sand media and based on gravel was found to be the more feasible and efficient setup to remove DBPs for the galvanized iron pipes distribution network medium.
