Science panel confirms low-dose estrogenic effects • 500A
Understanding Microcontaminants in Recycled Water • 508A
To the surprise of some observers, scientists have concluded that low-dose effects associated with estradiol and some estrogenic compounds are clearly demonstrated in animals.
Despite public concerns, the use of recycled water is growing, as water supply resources are being stretched to their limits. David Sedlak, James L. Gray, and Karen E. Pinkston discuss the increased attention being given to detecting, treating, and removing problem contaminants.
Energy-gobbling water heaters soon passé? • 501A
A new water heater could dramatically reduce energy use and carbon emissions.
The Complicated Challenge of MTBE Cleanups • 516A It is not easy to clean up MTBE plumes. Pumping rates can affect contaminant transport and produce unforeseen problems. Lisa Dernbach's discussion serves to remind water resource managers that wells serve both as water supply sources and hydraulic control devices and should be treated as such in the decision-making process.
