Nitrate in water is undetectable without testing because it is colorless, odorless, and tasteless. A water test for nitrate is highly recommended for households with infants, pregnant women, nursing mothers, or elderly people. These groups are the most susceptible to nitrate or nitrite contamination.
On Feb. 12, 1990, Nelson Mandela was released after 27 years in prison. He was named president of the ANC and in 1993 was awarded the Nobel Peace Prize. The following year, the ANC emerged victorious in South Africaâs first democratic elections with universal suffrage.
During the whole of the 1950s, Mandela was the victim of various forms of repression. He was banned, arrested and imprisoned. A five-year banning order was enforced against him in March 1956.
