Abstract

Government plays the most important role in improving the waste management system. Incineration system can be introduced into the waste management system to incinerate specific type of waste. This will increase the availability space for the landfilling process. However, the incineration process must be carried out with full pollution control system to prevent and minimize the pollution that might cause during the incineration process. Other than that, the government should encourage the public to separate out the waste into different categories before the collection of the waste by the waste management company. This can be implemented by providing guideline for the separation of waste methods as well as encouraging the public to be responsible for own produced waste. The dumpsites must also be improved and it is suggested that all dumpsites used are engineered sanitary landfill. An engineered sanitary landfill will reduce the impact of the pollution towards the environment to the minimum. Better tools also must be included in the sanitary landfill system to monitor the condition of the landfill site. This will prevent the happen of any unexpected conditions and can be resolve before the happening of the unexpected condition. Last but not least, the government should implement new charging fee system for the waste management. The charging fee should be based on the rate of waste generated but not flat pricing. This will help in reducing the waste generated as all individuals must pay for their own generated waste. The earth belongs to everyone which indicates everyone have the responsible to keep the earth clean and to reduce the waste produce.

Abstract

Water covers 70% of the world’s total surface, but only around 3% of it is freshwater that humans may drink and utilize for other purposes. Because of fast growth in many nations, the quality of groundwater is no longer adequate for human consumption. The objective of the study is to assess the groundwater quality of 18 locations in the Ropar wetland in Punjab, India, in different seasons and different source groundwater. When compared to uncontaminated natural groundwater, the groundwater obtained from the test sites had higher pH values. The amount of groundwater pollution is higher in the summer than in the winter. However, there are many challenges face by the groundwater quality research. The groundwater quality in any region of the world is very important towards the survival of human being. Long-term consumption of polluted groundwater with high levels of heavy metals will result in health issues such as difficulty breathing and renal failure.
