Overview of Singapore
Singapore was once a small country with limited natural resources and a small manufacturing base with mediocre infrastructure. It neither had domestic capital nor foreign investments. Today, the picture is quite a contrast. It is one of the world's leafing economies with robust infrastructure, sizeable foreign direct investments and an impressive record of phenomenal industrial growth.
Water Pollution rates
The chemical industry in Singapore is huge, varied and is growing at a fast rate. According to Singapore's Economic Development board, Singapore is among the top 10 petrochemical hubs in the world. It is a global leader in oil refining and is among the world's top three oil trading locations.
Due to this reason, we have concluded that the best results would be determined if we used the data collected for the percentage of BOD emissions from the chemical industry. Below is a table representing the percentage of BOD emissions of water pollution from the chemical industry.

Singapore's GDP is drastically different from its BOD. From both the graphs, it seems that the BOD rate of Singapore is fluctuating, whereas Singapore's GDP is steadily rising.
