General Background

After gaining considerable experience in economic and exploration geology, during which Mark headed projects in Alaska, Montana and Nevada for Anaconda Minerals Company, a move back to his homestate of New Jersey brought him into the heart of the developing environmental business.

Mark began a second stage of his career in geology with Earth Technology Corporation in 1985. He gained experience with regulatory compliance issues such as ECRA/ISRA and RCRA, hydrogeologic and geologic site assessments, underground storage tanks, and environmental audits.

In 1987, he established J. Mark Zdepski, Inc., now known as JMZ Geology. As president of this dedicated company, Mark personally maintains relationships with each of his clients, overseeing all projects delegated to other members of his team. His emphasis on science and accuracy extends to all members of his staff.

He is also an advocate for a sensible, scientific approach to environmental legislation. He has spoken to government, business and professional audiences about historic land-use and development impacts on soil and groundwater conditions in the metropolitan region.

 General Background

Prior to joining JMZ Geology, Mike acquired extensive experience in environmental geology in regulatory compliance, subsurface, historical, and remedial investigations. His close work with attorneys in litigation support yielded positive, economical results for clients.

At JMZ Geology, Mike has engaged in broad research into historical land-use impacts to soil and groundwater in the New Jersey metropolitan areas of Hudson and Bergen County. He has provided thorough analyses of proposed environmental legislation and the potential consequences to both community and clients.

Among the projects which Mike has had responsibility are: a historical background study and subsurface investigation for a leading New Jersey developer in blighted urban locations; evaluation and analysis of the developmental history of a major manufacturer company site and surrounding industrial property to determine the source of contamination; development and implementation of remedial activitiesand post-remediation monitoring for a metals recovery facility.

Mike's career history includes experience as a petroleum geologist concentrating in the Gulf of Mexico and the northern Applachians region.
