About the firm

DACCO SCI, INC. is a Columbia, Maryland-based corrosion engineering and materials technology enterprise founded in 1988 by Dr. Chester M. Dacres. For over 37 years, it has bridged laboratory research and field implementation, delivering cathodic protection design, nondestructive testing, electrochemical analysis, and forensic failure investigation for critical infrastructure across water utilities, rail transit, and marine sectors. Its proprietary in-situ EIS corrosion sensors extend lab-grade electrochemical impedance spectroscopy to real-world field conditions.
