H2A Environmental, Ltd. is very pleased to welcome Dr. Rangaramanujam Muthu to our team of non-aqueous phase liquid (NAPL) experts. Dr. Muthu is a co-author / co-developer of the forthcoming American Petroleum Institute software and guidance for the calculation of LNAPL transmissivity from LNAPL baildown tests for unconfined, confined, or perched LNAPL. In addition, Dr. Muthu has assisted with the development of ASTM International guidance on estimation of LNAPL transmissivity and LNAPL conceptual site model development. Among other project and technical tasks, he will be providing numerical analyses of NAPL nature, distribution, recoverability, and migration potential on various H2A projects.
Dr. Muthu’s experience includes sites impacted with petroleum hydrocarbons and chlorinated solvents. He has conducted NAPL nature and extent studies, NAPL mobility and recoverability field investigations and modeling, risk assessment and vapor intrusion analyses, statistical analysis and interpretation of a wide range of environmental data, guidance document development and training for software, and report preparation consistent with state and federal environmental regulations.
Dr. Muthu received his Bachelor of Science degree in Civil Engineering and his Doctorate in Environmental Engineering from the University of Houston. His doctoral dissertation is entitled “Residual NAPL Saturations in Unsaturated Soils for Two- and Three-Fluid Phase Systems”, and dealt with analysis and evaluation of residual NAPL saturation in various media subject to various hydraulic head stress levels. Dr. Muthu is an active member of ASTM International, the American Society of Civil Engineers, the Texas Association of Environmental Professionals, and the Society of Petroleum Engineers.
