Directions: Read each statement and decide whether it is an example of point source or non- point source pollution. If it is an example of point source pollution circle the pointed finger. If it is an example of non-point source pollution circle the non-pointed finger. 1. Loose soil at a construction site. (1) Fisherman crodes a stream bank. (C)3. Fertilizer on a farmer's field. 4.

A sewage treatment plant overflows during a storm. e) 9. Acidic water seeps from a coal mine. 10. An oil tanker spills oil into the ocean. 11. An offshore oil well starts to leak oil 12. Oil leaks onto the road after a car crash. 13. Manure mixes with rainwater and washes into a stream. 14. A homeowner pours oil down the storm drain. 15. Golf courses spray too much fertilizer. 16.

## Step 1<br />The first step is to understand the difference between point source and non-point source pollution. Point source pollution refers to the pollution that comes from a single, identifiable source, such as a pipe or a drain. Non-point source pollution, on the other hand, comes from many diffuse sources, such as rainfall or snowmelt moving over and through the ground.<br /><br />## Step 2<br />Next, we classify each statement into the appropriate category based on the definition of point source and non-point source pollution.<br /><br />## Step 3<br />For example, loose soil at a construction site is a non-point source pollution because it is not from a single, identifiable source. Similarly, fertilizer on a farmer's field, oil running off a parking lot, weed killer sprayed on a front lawn, acidic water seeping from a coal mine, an oil tanker spilling oil into the ocean, an offshore oil well starting to leak oil, oil leaking onto the road after a car crash, a homeowner pouring oil down the storm drain, a homeowner dumping a bottle of old weed killer into the street, and toxic liquids leaking out of a landfill are all examples of non-point source pollution.<br /><br />## Step 4<br />On the other hand, a fisherman eroding a stream bank, a septic system leaking, a sewage treatment plant overflowing during a storm, and a homeowner dumping a bottle of old weed killer into the street are examples of point source pollution because they come from a single, identifiable source.
