According to (Turks & 2014) only a small portion of the earth’s water is fresh however a larger portion of this fresh water is ice or glaciers. This mean the earth is only able to use the small portion to live on which is why it is important to be able to filter water and have alternative ways of reusing water. According to (Weber‚ 1973-07) the EPA has conducted studies not only to check for water quality but also to test for good and bad water standard
