Demonstrate point and nonpoint sources of pollution and their effects on wetlands, estuaries, the ocean, beaches, and even coral reefs and shellfish beds. This model represents typical sites found in a coastal area and watershed, including dredged channel, resort community, treatment plant, gas station, underground storage tanks, marina, and residential homes with septic tanks. Effectively teach the flow of rainwater runoff and what is washed away on its journey to the ocean. Dramatically illustrate groundwater contamination. Students implement best management practices on the model and experience the difference they make in preventing water pollution. Includes coastal landscape top with clear base, detailed user's guide, plus the following materials.
