Drinking Water Samples

Pesticides residues were determined quantitatively in drinking water samples collected fromdistrict Charsadda of the province Khyber Pakhtunkhwa, Pakistan employing GC-MS technique. Thesurvey was conducted soon after the flood in 2010. Aldicarb (0.003 mg/L) was found only in C7, whileresidues of acetachlor (0.001 mg/L) was found in C8. Among the pesticides quantified Chlorpyrifosdelivered highest amount of residues in C8, C9, C10, C11 and C12. Residues of o, p'-DDT were foundhigher in C1 to C6 than the permitted value (0.002 mg/L), while higher concentration of Pyridaben thanthe allowed value (0.0001 mg/L) was resulted in C1, C5, C6 and C14. Residues of Carbofuran, Atrazine,a-Endosulfan and Dieldrin, b-Endosulfan, Difenoconazole-1 and Difenoconazole-2 were not detectedin any of the collected water samples. Concentrations of rest of the pesticides residues detected in watersamples were within the permissible limits. The study revealed that water samples collected from districtCharsadda are highly contaminated with pesticides, which is a health risk factor for the inhabitant ofthis areas.

Drinking Water Samples

Over 2000 surface, ground and raw drinking water samples have been analyzed in the frame of different monitoring projects in Hungary and watercourses in neighboring countries between 1990 and 2015. Effects of pesticide contamination on ecological farming and drinking water supply have been assessed. Main water pollutant ingredients of agricultural origin in Hungary are herbicides related to maize production. After EU pesticide re-registration, diazinon, atrazine, and trifluralin gradually disappeared as contaminants. High levels of water soluble pollutants (e.g., acetochlor) in surface water result in temporarily enhanced levels in raw drinking water as well. Extreme levels observed for herbicide residues were of agrochemical industrial origin.

The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major constituent of THMs detected was chloroform in winter (92.34%) and summer (93.07%), while the other THMs determined at lower concentrations. Summer and winter concentrations of total THMs at places exceed the levels regulated by UEPA (80 μg l-1) and WHO (100 μg l-1). GIS linked temporal variability in two seasons showed significantly higher median concentration (2.5%-23.06%) of THMs compared to winter.
