- Abstract:
This lesson plan helps students understand the factors that affect water quality and the conditions that allow for different animals and plants to survive. Students will look at the effects of water quality on various water-related activities and describe water as an environmental, economic and social resource. The students will also learn how engineers use water quality information to make decisions about stream modifications.

- Abstract:
This EPA site provides links to introductory information about the Gulf of Mexico dead zone. It offers answers to questions such as: what is the hypoxic zone, how did it form, what strategies are being implemented to remedy it, and what is the government doing. It also features links to various regions within the Mississippi River Basin, allowing users to explore issues in their own area.

- Abstract:
This USGS site provides access to data sets collected by the National Water-Quality Assessment Program. It features fact sheets, reports, bibliographies, additional data sets and links to other resources about nutrients in streams, rivers and aquifers of the United States. The site briefly explains what nutrients are, how they are used in the agricultural industry, how they react chemically in the environment, some of the transport processes that introduce them to surface and groundwater, and why excessive nutrients create water quality problems.

- Abstract:
The purpose of the following series of activities is to help students visualize the dead zone and to provide them with dissolved oxygen (DO) data to analyze and interpret. Students will plot and analyze DO from the July 23-28, 1993, scientific cruise in the Gulf of Mexico. The activities are designed to engage the students individually, within a group and as a class to plot, observe, analyze and interpret several different spatial slices of the dead zone. In addition, these graphing activities can also be used to graph other variables such as salinity, density and temperature. The five graphing and mapping activities are described in order from simplest to most complex.

- Abstract:
In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.

- Abstract:
Emphasis on mathematical models for predicting distribution and fate of effluents discharged into lakes, reservoirs, rivers, estuaries, and oceans. Focuses on formulation and structure of models as well as analytical and simple numerical solution techniques. Role of element cycles, such as oxygen, nitrogen, and phosphorus, as water quality indicators. Offshore outfalls and diffusion. Salinity intrusion in estuaries. Thermal stratification, eutrophication, and sedimentation processes in lakes and reservoirs.
