Pollution and Materials: Metals and Non-metals

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.
