Ecosystem Consulting Service, Inc. was founded in 1980 by Dr. Robert W. Kortmann, Ph.D. (Environmental Science, Rutgers University; Limnology/Ecosystem Ecology University of Connecticut).

ECS, Inc. consists of two divisions; Research and EcoLogial Technologies (EcoTech).  The Research Division is run by Dr. Robert Kortmann and staffed by qualified Field Biologists.  The Research Division conducts problem solving diagnostic-feasibility studies, monitoring programs, client-based monitoring programs, method and apparatus development and design. In 1985, Charles Bonnell joined ECS, Inc to help develop the EcoTech Division.  EcoTech provides design, fabrication, installation, and maintenance of specialized apparatus, as well as SCUBA inspections/surveys, and operation/maintenance services.

Our expertise in Applied Limnology has taken us from cost-to-coast, and internationally as far away as Sao Paulo, Brazil.

ECS, Inc. and its professional staff continue to maintain its links to the academic community and private sector through its active participation in:

• American Water Works Association AWWA
• North American Lake Management Society NALMS

Water Resource Management that works in concert with Nature!

Our science-based approach results in effective and innovative resource quality improvement.  This approach has led us to develop several innovative methods for varied applications.  Some methods include:

• Winter Temperature Manipulation to control impacts of an invasive fish species; land-locked alewife.
• Aeration Technology that uses photosynthesis as an oxygen source.
• Nutrient Inactivation Technology that uses iron generated by anaerobic respiration in a lake.
• Gravity-driven Flow Routing Technology for depth-selective inflow or outflow.
• Downflow Contactor Oxygenation Technology that requires no in-lake mechanical or electrical parts.
• Resource Management Equipment powered by wind and/or solar.

To provide cost-conscious, state-of-the-art water resource management, including:

• Research
• Consulting
• Watershed Management
• Apparatus
• Implementation
• Operation & Maintenance
• Monitoring
