Contaminated water supplies have become local problems in communities across the United States and the world. Though dramatic situations in Flint, Michigan, and in New Orleans after Hurricane Katrina catch the headlines, neighborhoods, and communities across our country are facing water quality issues in their groundwater, swimming pools, and community and backcountry lakes and streams. Microscale and nanoscale water filters hold the key to removing even the smallest of pathogens from the water. In this module, students will use a model to illustrate the relationships and interactions between clean water, micro- and nano-contaminants found in local water sources, and mechanical water treatment mechanisms. Then they will evaluate competing design solutions to produce drinkable water based on empirical evidence and/or logical arguments regarding constraints, including cost and safety while considering social and environmental impacts.
