Impact of wastewater irrigation on groundwater in the Lahore region and contamination source identification

Organic pollutants in groundwater samples were analyzed for the very densely populated ‘Lahore’ city and its surrounding ‘Mangamandi’ areas of Punjab-Pakistan, where composite (industrial and urban) wastewater is used for cultivation of crops and vegetables. The samples were pre-concentrated using t...
