Nutrient Loading Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Castendyk, D.N., T. Meixner, and C.A. Gibson. 6 June 2015. Project EDDIE: Nutrient Loading. Project EDDIE Module 7, Version 1. Module development was supported by NSF DEB 1245707.
Estimating nutrient loads is a critical concept for students studying water quality in a variety of environmental settings. Many STEM/Environmental science students will be asked to assess the impacts of a proposed anthropogenic activities on human water resources and/or ecosystems as part of their future careers. This module engages students in exploring factors contributing to the actual loads of nitrogen that are transmitted down streams. Nitrogen is a key water quality contaminant contributing to surface water quality issues in fresh, salt, and estuarine environments. Students will utilize real-time nitrate data from the US Geological Survey to calculate nitrate loads for several locations and investigate the interplay of concentration and discharge that contributes to calculated loads.

Unit 5: Agriculture and Freshwater Pollution part of Water, Agriculture, Sustainability
Chris Sinton, Ithaca College
Units 3 and 4 of this module explored how water resources are used for agriculture in the United States and how this can vary depending on location. In Unit 5, students explore how agricultural practices can affect ...

Unit 4: Irrigation and Groundwater Mining part of Water, Agriculture, Sustainability
Chris Sinton, Ithaca College
Is groundwater mining sustainable? In Unit 4, students compare and contrast long-term (decades) groundwater well levels in six states representing the East Coast, West Coast, and Midwest Plains states. Satellite ...

Lesson 1: Water Resources and Water Footprints (High School) part of Teaching Activities
