Photographer's Note

If you think life is difficult, spare a thought for people in developing countries. This women was washing on the car ferry dock in water which has the colour of tea from the humic acid/ organic compounds which seeps from the forested area. I have not been to the Amazon River as yet but documentaries show that that water is also coloured like tea for the same reason. Sorry it is not too sharp but think is has some emotive look.

Notes on colour of water in Amazon:
The varied terrain allows for three basic types of water that float along the path: Whitewater, clearwater, and blackwater.


The whitewater rivers are a dirty, yellowish color. The color is caused by large accumulations of silt and other sediment in the water. The water comes from the Andes, washing off the soil nutrients from the young rocks.


Clearwater rivers are a blue-green color and they carry little sediment. The highlands that the clearwater rivers flow from are made of hard rock and not easily eroded.


Finally, the blackwater rivers are the color of dark tea. They have little sediment like the clearwater rivers because the rocks they wash over are so old that they have been leached of minerals.


The different types of river meet at various sections along the way, making interesting patterns as they pass by each other, side by side, with different colors. While it may seem like a small difference to us, it makes a large difference to the wildlife which are more often found in whitewater rivers that are full of sediment.
