The Amazon River of South America is made up of a network of
tributaries from across different countries that drain into the main body of
the river. The Amazon River has approximately 1,100 tributaries. The Amazon
River, spanning two-fifths of an entire continent, is the lifeblood of the
world's largest ecosystem. The primary objective is to mitigate the
environmental impact of deforestation, urbanisation, cultivation, invasive
species, soil erosion, and sedimentation on declining Amazon water quality. The
Amazon River is fed by a series of tributaries that are categorised into three
types depending on the terrain they pass through and the sediments they pick up
along the way. First is the Whitewater Rivers, which are brown because of large
amounts of soil-based sediments. The Blackwater Rivers, which are deep brown,
are caused by decomposing plant materials. These materials make the waters
highly acidic and inhospitable to parasites and bacteria. The Clearwater Rivers
flow in highlands over ancient rocks whose sediments were washed off long ago.
A Water Quality Index (WQI) was used based on nine variables analysed. The
Internal Quality Assurance (IQA) was an important tool used to evaluate the
water quality of the studied rivers. Water pollution in industrial and urban
areas is intense. Water use for various urban purposes needs to be restricted.
