Natural Resources in the Agricultural Industry Objective: Students will be able to cite 3 examples and sources of point and nonpoint water pollution.

Understanding Point vs. Nonpoint Water Pollution Water pollution can come in many different forms and methods. Many times water becomes polluted from an obvious source. For example, oil tankers that accidentally spill oil into the ocean.

Understanding Point vs. Nonpoint Water Pollution Types of pollution in which the source can be easily pinpointed are called point source.

Understanding Point vs. Nonpoint Water Pollution Point source water pollution occurs when the contaminant comes from an obvious source.

Understanding Point vs. Nonpoint Water Pollution Point source contaminants come from industrial, commercial, and residential sources, often as byproducts of daily operations. Examples: Tanker spills Discharge from industrial sites Animal Waste Management problems Sewage spills Discharge from sewage treatment plants

Understanding Point vs. Nonpoint Water Pollution What happens to the water that goes into a storm drain?

Understanding Point vs. Nonpoint Water Pollution What do you think we would call a pollutant that comes from a source that is not easily identifiable or originates from a number of sources? That’s right! Nonpoint source pollutants are sometimes difficult to trace to their original source. For the next slide, describe the pollution that may be coming from each source.

Understanding Point vs. Nonpoint Water Pollution

Understanding Point vs. Nonpoint Water Pollution Nonpoint source water pollution occurs when the contaminant comes from a source that is not easily identifiable or from a number of sources. 1. Nonpoint source pollution often originates as precipitation that collects contaminants as it travels across the ground until it becomes polluted. 2. If nonpoint source pollution is found over a large area, then it is difficult to pinpoint the exact origination of the contamination.

Understanding Point vs. Nonpoint Water Pollution Examples of nonpoint source water pollution include: agricultural or urban runoff (fertilizers & sediments), runoff from parking lots (grease, gasoline, anti-freeze), salt contamination from road de-icing, and acid rain.

Understanding Point vs. Nonpoint Water Pollution Show What You Know! On one side of a piece of paper, write the definition, list 3 examples, and illustrate 1 of the examples of point source water pollution; and then do the same for nonpoint source water pollution on the other side of the paper. Be sure to turn this in to Mr. Parris by May 6, 2019!
