How Does the Niagara Whirlpool Get Involved in Niagara River Self-Purification?

The Niagara River self-purification through the natural formation of froth at a site of the Niagara Whirlpool basin has been investigated. It is shown that the naturally formed froth on the water surface of the Niagara Whirlpool contains a greater concentration of nutrients, trace metals and phenol in comparison to subsurface water. The natural pollutants removal process is explained in detail. As a result, the Niagara River at the Niagara Whirlpool basin possesses its own natural capacity to self-purify through the natural formation of froth. We can conclude that the Niagara Whirlpool is a natural source of Niagara River self-purification. The necessity for the long-term research on the sites of Niagara River for developing the remediation strategies is pointed out.
