2007 Ground Water Summit
Tuesday, May 1, 2007: 10:00 a.m.-3:30 p.m.
Pecos (Albuquerque Convention Center)
Ground Water Geochemistry
This technical session will focus on several aspects of ground water geochemistry. Specific topics will include natural water chemistry, hydrochemical aspects of contaminant migration, ground water age, water-treatment technologies, influence of aquifer pumping on ground water chemistry, novel analytical methods, and hydrochemical aspects of ground water remediation. The goal of this technical session is to bring together national and international scientists and engineers from universities, national laboratories, municipalities, and industry to share their results with colleagues and interested scientists. Hydrochemical aspects of field investigations, and experimental studies will be included in this session.
