AB  - Water resources have been contaminated by pesticides due to the different 
      activities of human beings. Different studies documented that advanced water 
      treatment systems can eliminate pesticides while conventional and household 
      treatment technologies are not well studied. The main aim of the present study is 
      to determine the effect of conventional and household water treatment 
      technologies on the removal of pesticide residue in drinking water. Water samples 
      were collected from the Gibe River (intake point), from each treatment process, 
      and from the distribution system. To determine the effect of the household water 
      treatment process (solar disinfection and boiling), pesticides were spiked into 
      distilled water and then passed through solar disinfection (SODIS) and boiling. 
      The extraction of samples was conducted by following a low-density-based 
      dispersive liquid-liquid microextraction procedure. The result of the study 
      revealed that almost all studied pesticides except o p-DDT were detected in water 
      samples. Most pesticides that were detected in water samples from our study areas 
      exceeded the maximum residue limits (MRLs), except for p,p'-DDE. The percent 
      reduction of pesticide residue after post-chlorination by conventional water 
      treatment ranges from 11.7% (from 70.83 mug/L to 62.54 mug/L) for p p-DDD to 97.29% 
      (5510.1mug/L to 149.5mug/L) for Dimethachlor, and the percent reduction of 
      pesticide residue by SODIS and boiling ranges from 2.31% (o p-DDT) to 54.45% 
      (Cypermethrin) and 27.13% (gamma-Chlordane) to 38.9% (p p-DDE) respectively. This 
      indicates that treatment technologies are important for the reduction of 
      pesticides in water. Since studied pesticides are persistent and the resides were 
      exceed MRL (have a health impact), monitoring of pesticides in treatment plant 
      units is necessary and treatment technology improvement is important to allow 
      further removal of pesticides.
