A better way to detect pathogens in waterways:
ARS scientists have come up with a way to detect pathogenic Escherichia coli and Salmonella bacteria in waterways at lower levels than any previous method--just a few cells of pathogenic E. coli and Salmonella in a 10-liter water sample. (2/8) http://www.ars.usda.gov/is/pr/2011/110208.htm

A green way to cap old landfills:
An ARS microbiologist and a safety manager with the agency have worked with the U.S. Environmental Protection Agency and private consultants to design and conduct a pilot study for an alternative way to cap landfills, using trees and shrubs planted in a mix of topsoil and compost, rather than the traditional clay caps.
