Current research and/or projects
Conducting monitoring and surveillance projects to assess status and trends in water quality, presence of current and emerging issues in the aquatic environment and the effects of activities on the aquatic ecosystem
- Conducting surveillance projects to address the presence and effects of current and emerging issues in the aquatic ecosystem, as well as the success of management actions, largely through national programs, such as the Chemical Management Program, Clean Air Regulatory Agenda, Pesticide Science Fund and priority ecosystem initiatives (Georgia Basin Action Plan)
- Reporting on monitoring and surveillance results through the web and peer reviewed scientific journals
Professional activities / interests
