The U.S. Environmental Protection Agency (EPA) has issued new protective guidance for cleaning up perchlorate contamination situations, recommending a preliminary clean-up goal for perchlorate of 24.5 parts per billion in water. EPA's guidance is derived from the agency's reference dose for perchlorate, which is based on the 2005 recommendations and conclusions of the National Academy of Sciences.

NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus. The rare occurrence of liquid water so near the surface raises many new questions about the mysterious moon.
The Commerce Department has said that housing starts zoomed up 14.5 percent in January to the highest level in nearly 33 years as groundbreaking on new single-family houses hit a record high.
Chemical engineer Kamalesh Sirkar, Ph.D., a professor at New Jersey Institute of Technology and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water. Sirkar says that using his technology, engineers will be able to recover water from brines with the highest salt concentrations.
Ensuring stable water supplies has grown more complex as the challenges facing water managers continue to mount, especially in the West. The U.S. Geological Survey (USGS) has released a report that examines Western water availability and how science can help ensure an adequate water supply in the future.
The retreat of a massive ice sheet that once covered much of northern Europe has been described for the first time, and researchers believe it may provide a sneak preview of how present-day ice sheets in Greenland and Antarctica will act in the face of global warming.
