Announcements

July 2016, a new project focused on the timing and mechanisms of phosphate addition for control of lead in drinking water distribution systems officially started.  The work is a collaboration with Jill Pasteris in Earth and Planetary Sciences and with Yandi Hu at the University of Houston.  The project is supported by the National Science Foundation and the Water Research Foundation.

June 2016, we published MINFIT as a simple tool to enable MINEQL+ to fit experimental data. Download the program and tutorials here.

May 2016, Dan participated in the workshop "Science and Technology to Ensure the Safety of the Nation's Drinking Water" convened in Washington, DC by the President's Council of Advisors on Science and Technology.

Dec 8-11, 2015, Dan visited the Hong Kong University of Science and Technology in his new role as McDonnell Academy Ambassador to HKUST.  While in Hong Kong he was hosted by Professor Irene Lo to give presentations in the Department of Civil and Environmental Engineering and at the Hong Kong Institution of Environmental Engineers.

Dec 12-16, From Hong Kong Dan traveled to Shanghai to visit Xiaohong Guan at Tongji University.  While in Shanghai he also gave a presentation at Fudan University hosted by Weihua Song and traveled to Hefei to visit Han-Qing Yu at the University of Science and Technology of China.
