WED and Watershed 1

What is subsidence?

• fertilizing crops

• too much concrete in an area

• sinking of the ground due to over pumping water from aquifers

• flooding caused by drainage issues

What is Point Source Pollution (PSP) ?

• When you cannot trace the direct source of pollution
• When you can trace the point of the source - "pipe to source"

When fertilizers enter surface water, they cause problems in 
the watershed by -

• increasing the amount of nutrients available to fish in lakes and streams.
• 
  clogging narrow streams and preventing water from flowing properly.
• raising the water level in nearby rivers to levels leading to flooding.
• causing rapid algal growth that decrease oxygen levels and choke aquatic life.
