REVIEW:

What is water pollution?

Water pollution is the contamination of a water source by humans or water pollution is anything in water that does not belong.

When rain falls from the sky, it is clean. However, when it hits the ground, rain collects pollution (litter, oil, chemicals, etc.), eventually depositing polluted rain water into the nearest body of water (ponds, lakes, streams, rivers, etc.).



REFLECT:

Look at the Pollution Map (Workbook pg. 7)

Identify the following pollutants on the map and their location (Residential Area, Golf Course, Construction Site, Industrial Plant, and Farm).

*Litter
*Soil
*Manure
*Pet Waste
*Fertilizer
*Pesticide
*Oil
*Toxic Chemicals
*Soap

Locate the storm pipe on the Pollution Map (Workbook pg. 7).                                                                      

REVIEW:

Point Source Pollution:

There is an identifiable point where pollution is entering into the water. Most often, point source pollution comes through a pipe. A simple way to remember this is you can “point” out where point source pollution is coming from.

Non-point Source Pollution:

The source of pollution is not identifiable. The pollution is entering water bodies from various areas. You cannot detect or point out where it is coming from.

REFLECT:

Look at the Pollution Map (Workbook pg. 7)

Identify the sources of pollution on the map.

Below list five different pollutants found on the map and identify their source as point source or non-point source.
