USGS research on fracking

The U.S. Geological Survey, in a research paper published in late December, reports new criteria for predicting where the disposal of salty waste water from hydraulic fracturing is most likely to contaminate wetlands. Read a Los Angeles Times article about the research. Check out a USGS web site devoted to research on fracking. The site has a link to the research paper. Register to attend a Jan. 30 Freshwater Society lecture on fracking and water quality.
