The president and CEO of LRM Consulting, Inc., in Burlingame, California, Dr. Mehrdad Javaherian provides consulting services in environmental remediation and engineering design. Dr. Mehrdad Javaherian also serves as a Principal Consultant at Endpoint Consulting, Inc., in San Francisco, where he provides expertise in areas like sustainable remediation and public health.

Endpoint Consulting facilitates the creation and use of sustainable and green technologies. The company has introduced programs and technology related to the conservation of energy and soil contaminant thermal treatment, including its patented Vapor Energy Generator (VEG) technology.

A fully enclosed, mobile soil remediation system, the VEG eliminates the need to transfer contaminated soil to offsite landfills by treating the full suite of organic compounds and select heavy metals thermally through generation of steam upwards of 2000 degrees Fahrenheit. In doing so, the VEG induces desorption of chemicals from soils, treating the induced vapors through its proprietary filtration system, and converting much of the treated stream into a renewable source of synthetic gas (syngas) used to fuel the VEG’s operations. Featuring a fully enclosed, close-looped process, the VEG technology can be scaled for use in any size project and uses emissions-reducing filters, significantly shrinking the carbon footprint typical of other soil remediation systems.

A civil engineering graduate of The California Polytechnic University, Mehrdad Javaherian also holds advanced degrees in Public Health and a PhD in environmental epidemiology. He leverages his training to serve as an environmental remediation consultant with Endpoint Consulting, Inc. Dr. Mehrdad Javaherian also holds several patents for a sustainable vapor energy generator for use in soil remediation .

Scientists have developed a number of methods for soil remediation, including:

Thermal soil remediation. This method entails heating contaminated materials at temperatures of 650-900 degrees Fahrenheit in the primary treatment unit (PTU), which evaporates water and hydrocarbon impurities. The materials are then sent to a cooling unit via a conveying system prior to testing and recycling.

Bioremediation. The bioremediation technique relies on bacteria to break down soil pollutants and hydrocarbons. One of the advantages of this method is that the microbes die off after the bacteria consume all the contaminants.

Air sparging. Also referred to as air stripping, the air sparging method involves injecting large volumes of air into polluted soil to push out organic vapors and then treat them through carbon filtering.

Dr. Mehrdad Javaherian is the technical director for remediation services at LRM Consulting, Inc. Dr. Mehrdad Javaherian is also a Principal Consultant at Endpoint Consulting Inc., providing services to the US Army Corps of Engineers, the Navy, the Air Force, and the Pacific Gas and Electric Company. He holds a number of patents for a green vapor energy generator technology used for in-situ and ex-situ soil thermal desorption. Much of his work involves remediation of recalcitrant compounds.

Environmental remediation is the process of removing contaminants from soil, sediment, groundwater, and surface water. Environmental remediation can generally be categorized as in-situ or ex-situ. In-situ involves treatment without soil excavation, while ex-situ means treatment of the surface after soil excavation.

A site assessment usually precedes the remediation process. Guidelines are available from the US Environmental Protection Agency on how to proceed with treatment. The agency also imposes sanctions in cases where the treatment process is delayed or otherwise obstructed.

MTBE in California Groundwater

An environmental health expert, Dr. Mehrdad Javaherian leads as Principal and Technical Director of LRM Consulting, Inc. Through the firm’s focus on the private sector, Dr. Mehrdad Javaherian consults for companies such as Lake Tahoe Investments on issues like methyl tertiary butyl ether (MTBE).

MTBE is a substance found in gasoline. Its volatility caused California and Nevada to ban it in 2004 and 2007, respectively. However, the chemical is still found in well water located in South Lake Tahoe.

In 2014, samples collected from a well used by Mark Twain Hotel on Park Avenue showed concentrations of MTBE above drinking-water standards. This was a result of the establishment’s former owners not having cleaned up the groundwater fully, despite complaints dating as far back as 1991.

Local wells in 13 other areas also indicated troubling amounts of MTBE. The wells were placed out of service, and South Tahoe Public Utility District took action against oil companies to win a multimillion-dollar judgment.
