Symposium to focus on hard

The International Symposium on Health Aspects of Magnesium and Calcium in Drinking Water will be held on April 24-26 in Baltimore, Md. NSF International and the International Life Sciences Institute are planning the NSF World Health Organization Collaborating Center event to discuss the health benefits of consuming hard water. Immediately following the symposium, a WHO expert meeting will convene to examine the information and prepare recommendations to WHO that could be used in its Desalination Guidance (2006) and WHO Guidelines for Drinking Water Quality (2008).
