Homework Help River Pollution Photo

Our rivers, lakes, and beaches are beautiful, but are they safe? Every day, the toxic runoff from parking lots, busy roads and quiet subdivisions makes its way into our streams and oceans. Even the oil burning off from cars on the roads gets washed into the groundwater and streams by way of the storm drain every time it rains.

The more houses we build, the more pollution we will add to our environment. Every time we lay down a new parking lot or piece of roadway, there is an impact on our environment.

Planning growth and designing communities are part of the local government's job. If you are curious about what changes are about to happen where you live, start reading the local news sources, and save stories about development. If something concerns you, you can contact your officials to let them know how you feel. At home, there are things you and your family can do to cut back on water pollution in your neighborhood:

  • Don't litter. Trash that is thrown in the streets usually winds up down storm drains.
  • Watch those sprinklers. Place water sprinklers so they water the grass or flowers and not the street or sidewalk. Also, don't water on windy days or in the hottest part of the day so more water will be absorbed by plants and less will be wasted by the wind and the sun.
  • About fertilizers: they are good for the garden, but too much of a good thing can hurt the environment by causing algae bloom. Check with a garden store to find out how much fertilizer your soil needs and consider using organic fertilizers.
  • Compost your grass clippings to make natural fertilizer or leave it on the lawn as a source of nutrients.

The River Thames
From Source to Sea

The River Thames is the cleanest river in the world that flows through a major city. This is a major feat considering that fifty years ago the river was so polluted that it was declared biologically dead.

From 1830 to 1860 tens of thousands of people died of cholera as a result of the pollution in the Thames. Sewage was being discharged directly into the Thames. Despite the foul smell, people continued to wash and bathe and drink from the river.

In 1855, a letter from Michael Faraday in The Times newspaper, London, described the polluted state of the River Thames he had observed on a boat trip:

"The whole of the river was an opaque pale brown fluid. ....... surely the river which flows for so many miles through London ought not to be allowed to become a fermenting sewer."

A few years later the curtains in the Houses of Parliament had to be soaked in lime to stop the odours (bad smells) from preventing government from carrying on.

In 1878 the pleasure steamship Princess Alice sunk in a river collision. Most of the 600 or so passengers who died did not die from drowning, they died because of the pollution in the river.

Dickens, in his novels described the Thames as 'a dank, stinking sludge, the scene of murders and crime'.

The Embankments
A major enterprise during the Victorian period was building the Thames embankments in 1861, under the direction of Sir Joseph Bazalgette. Built over formerly tidal foreshores, these narrowed the river and speeded its rate of flow, enabling it to become a more efficient remover of the increasing tons of rubbish thrown into the river. At the same time, the embankments allowed for the building of riverside roads and walkways raised above, and effectively concealed the huge pipes that carried the newly created sewage services and water mains.

Treatment Plants
It was decided that 'Treatment plants' should be built to clean the water from the Thames before it was pumped to homes. The treatment plants also cleaned dirty water from homes before it went back into the Thames. Not only did the people's health improve but also the water in the Thames became cleaner.

During the Second World War (1939 - 45) many treatment plants were damaged by German bombs. A lot of dirty water went into the Thames and killed the plants and fish living in it.

New treatments plants were built in the 1950s. In the 1960s new laws were made to stop factories letting their dirty water go into the river.

Today more than half of London's sewage sludge is sold in pellet form as fertilizer for agricultural use.
