Stellar Environmental Solutions’ principal and associates have over the aggregate experience to complete projects through  initial site investigation to regultory closure and take pride in their professional accomplishments, both as individuals and as team members. Key personnel and associates are described below.

 

Richard Makdisi

P.G, Principal Geochemist & President

Richard Makdisi, a California Professional Geologist, is principal geochemist and President of Stellar Environmental Solutions, which he founded in 1995. He has more than 30 years of experience in hazardous management, geoscience engineering, geochemistry, and hydrogeology. 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 and voluntary site cleanups 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 the development of complete site conceptual models and evaluating the most effective corrective action technologies, overseeing their implementation and achieving site regulatory closure for clients.
