It is estimated that salt costs the users of the Murray River $ 47 million each twelvemonth to filtrate the H2O for use.

Dame usage in river had changed the full river and life along the river side. Hume Dame had limited the sum of H2O flow and highly lowers the H2O degree. The lower H2O degree makes agricultural diminish its productiveness and salt is addition because that H2O degree is excessively low so it ca n’t thin the H2O. Because of the salt so carnal and works had a really large impact and at the Murray oral cavity at Goolwa, it had been found that the H2O is merely similar sea H2O because of its pollution. And because of these effects, its affect the H2O usage of people and impact the people ‘s who use H2O from the river as H2O resource.
