Baltimore's Urban Streams
Baltimore, Maryland, is a major city situated on the Chesapeake Bay--a sprawling 64,000-square-mile watershed. Currently, the Chesapeake is facing an environmental crisis due to pollutants. Scientist Claire Welty of the University of Maryland-Baltimore County is monitoring the travel times of pollutants in the urban streams in and around Baltimore. Through her research, she hopes to gain an understanding of the urban water cycle, and how municipalities can better prevent pollutants from contaminating the greater watershed.
