  2. Pollution types- point source • Point source pollution = source of pollution is known and identifiable. • Real life examples= toxic effluents from a factory, agricultural run-off. Effluents= chemicals or fluid that flows out

  3. Pollution types- nonpoint source • Nonpoint source pollution = source of pollution is too widespread to identify or blame • Real life examples= urban run-off from roads and parking lots, neighborhood run-off from storm drains, sewage leaks such as pig waste or pesticides, and overfishingfrom fisheries.

  4. Ways to correct- nature Water is recycled through the water cycle. Water is filtered through percolation. This method is mostly effective but time consuming.
