A primary focus of CEC activities is applied research in drinking water microbiology, water treatment, and projects on environmental assessments and knowledge management. In addition to applied studies for our clients, CEC scientists generally have several ongoing research projects funded through competitive grants. CEC scientists present the findings of these studies at many national and international conferences each year. As they are completed, both types of projects are submitted to peer review journals, keeping CEC at the forefront of the water research community.
