THAMES RIVER REMEDIATION
Was so polluted the River Thames in the stretch of 70 km from Gravesend to Teddington Lock-in 1957, when he was tested by sampling by scientists, that no fish could livein its waters. In previous centuries had been an ideal place for fishing, from its estuary, where there were many saltwater fish-to shallow sites where salmon spawn reached, from the sea.
When thecity of London grew, increased production of waste, and many were thrown into the river. But pollution began to be a serious problem in the first decade of 1800, when they began to use the toilets.Before that, most of the wastewater of the city poured into pits and then scattered in the gardens.
The untreated water coming into the river stimulated the growth of bacteria. Gradually, they ended upwith oxygen in the water, which is essential for the life of the fish and plants
Population movements from rural areas to the big cities, especially London, because of the industrial revolution of thenineteenth century brought great pressure on the existing water supply and a consequent increase in the production of waste and spoilage. By 1805, 150,000 septic tanks were built to serve one millionpeople in London, short term solution was insufficient. Therefore, most people began to illegally connect their overloaded septic tanks to surface water pipe that ran into the River Thames, increaseduse of drinking water in London. These undesirable aspects, have become de facto sewers, were at one time the biggest health problem of the environment and consequent social center of the conflict.Thus, in 1848 the Thames was the source of all public scandal, the ill health of cholera were common and the mortality rate was approximately 2000 per week London.
Given this state of environmentalconditions, around 1864 the first plant was designed to treat wastewater from the city of London, which until 1874 only became fully operational. Consistent with this, came years of study and...
