Richard Makdisi, a California Professional Geologist and Registered Environmental Assessor, is Principal of Stellar Environmental Solutions, which he founded in 1995.  He has more than 26 years of experience in hazardous management, geoscience engineering, geochemistry, and geohydrology. Mr. Makdisi has hands-on experience in managing regional and site facility scale projects for a wide range of issues, from immediate response assessments to long-term planning studies. He has worked closely with the U.S. EPA, Cal-EPA, and Water Boards on RCRA and CERCLA sites to design and implement remedies to achieve regulatory closure for commercial and government clients. He has conducted Remedial Investigation/Feasibility Studies, Remedial Action Plans, Remedial Design, and remediation implementation. Mr. Makdisi has extensive knowledge of California hazardous waste, solid waste, water code regulations, and ARAR development, and has provided client-regulatory agency liaison services on major remediation projects. He has implemented soil-gas, geophysical, geotechnical, and hydropunch sampling investigations, and has completing 2D and 3D hydrologic and solute transport models to identify and solve problems related to water supply, salt water intrusion, hydrocompaction, and contaminant recovery. He has extensive experience in evaluating remedial technologies and overseeing their implementation.
