Abstract
This study was conducted on the canal water that flows besides an urea manufacturing facility. The study focused to evaluate the impact of facility’s effluents. The canal water quality is being affected drastically due to heavy load of pollutants discharged. Samples were collected by grab sampling method, from various locations. These samples were analyzed regarding physiochemical parameters, i.e. temperature, pH, TDS, TSS, BOD5, COD, heavy metals (Fe, Cu, Cr, Mn) and NH3 content. The canal water quality deteriorates after receiving a substantial load of effluents discharged from urea fertilizer plant. The results compared with WHO and NEQS, showed that the effluent samples had alkaline nature with a high level of ammonia and BOD5 and are not safe for aquatic life and environment. It is therefore recommended that discharge of untreated effluents should be stopped, or allowed within safe limits.
Highlights
Water is used for numerous purposes such as food production, irrigation, manufacturing, drinking and waste disposal [1,2]
The study has shown that effluents discharged into surface canal water cause drastic impacts on the aquatic life, animals, plants and humans
The results from samples taken from surface water represent that the effluents discharged from the plant contain adverse impacts on the quality of surface water
Summary
Water is used for numerous purposes such as food production, irrigation, manufacturing, drinking and waste disposal [1,2]. Due to its unique structure, water has the ability to suspend, dissolve, and absorb a number of compounds that deteriorate the purity of drinking water, as it acquires contaminants from its surroundings [3]. Ground and surface water can be polluted by industrial discharged effluents, sewage water and wastewater from contaminated sources [4]. A significant share of the industrial wastewater is being discharged into the water bodies without any proper treatment, subsequently reducing the quality of drinking water. Many countries have incorporated wastewater reuse as an essential measurement of water resources planning. Like Saudi Arabia and Jordan, have attempted to reuse the wastewater after proper treatment and have achieved significant success [6]
