Our Story

Over 45 years of diversified professional experience in a variety of phases of civil and environmental analysis, planning and engineering.  Pioneered engineering design and environmental studies for transfer/recycling centers, sanitary landfills and underground tank facilities.  Last thirty years have concentrated on environmental engineering, primarily associated with hazardous waste, dry cleaning facilities and underground fuel tank regulatory compliance, and expert testimony associated with recycling of hazardous materials, surface and subsurface soil and water contamination, including planning and supervision of site assessment of soil and groundwater, remediation by excavation and treatment, bioremediation and restoration of petroleum-contaminated and PCE-contaminated aquifers.  Designed/installed many methane gas barriers in Los Angeles City and Los Angeles and Orange Counties.

In 1998-99, Dr. Hekimian served as chief consultant and prime contractor to the Montebello Unified School District (MUSD) and coordinated a multi-faceted environmental investigation at the Suva Elementary and Intermediate schools (Suva) located in Bell Garden, California.  Suva is located in a mixed residential/industrial area and encountered Recognized Environmental Conditions (RECs) including the possibility of air, water and soil contamination and health risk effects from hazardous substances managed at the neighboring chrome plating facilities.  California EPA's Department of Toxic Substances Control (DTSC) served as the lead agency and HVN worked on behalf of MUSD to provide technical assistance to DTSC, including supervising and managing the cleanup of chromium-laden soil, conducting soil verification sampling, air sampling, and water sampling at the SUVA schools facilities, and providing base maps and drawings relative to the SUVA schools and surrounding areas.

From 1971 to 1988, Dr. Hekimian was a adjunct faculty member of the Systems and Environmental Engineering Departments at the University of Southern California.  In this position, he developed curricula and taught courses in solid waste management, resource recovery, environmental assessment and hazardous waste management to undergraduate and graduate students in the systems, civil, sanitary, and environmental engineering programs.  From 1974 to 1978, he coordinated and lectured at a week-long seminar at U.C.L.A. on "Resource Recovery from Municipal Solid Waste."
