Presenter

John W. Jengo, PG, LSRP   
Principal Hydrogeologist

Stantec, Inc.


Within four business days and after auditing participation, PCPG will circulate a PDH certificate documenting registrant’s participation time, not to exceed 60 minutes.

Level: Intermediate

Who should attend:  Environmental consultants, hydrogeologists, hydrologists, environmental scientists, biologists, ecologists, regulators, and site investigation, site remediation, and site restoration project managers.

Webinar Overview: Brief discussion about the process of investigating, calculating, and negotiating Natural Resource Damages (NRD) with regulatory agencies and how the settlement monies from contaminated sites were used to restore the Raritan River in central New Jersey via lowhead dam removals. A dam removal case study will also be presented. Intended outcomes include informing the webinar participants about the nationwide NRD process and how dam removals are planned, permitted, and accomplished.

About our presenter: John W. Jengo, PG, LSRP is a licensed Professional Geologist in several Northeastern and Southeastern states (including Pennsylvania) and a Licensed Site Remediation Professional (LSRP) in New Jersey, who works as a Principal Hydrogeologist in an environmental consulting firm [Stantec, Inc.] in southeastern Pennsylvania. He has degrees in geology from Rutgers University (1980) and the University of Delaware (1982). Between 1990-2012, he conducted the characterization and remediation of large, complex contaminated industrial sites throughout New Jersey, Pennsylvania, and Delaware, including at three of the seven refineries in the Delaware Valley. For the past 18 years, he has worked with various industrial clients and the New Jersey Department of Environmental Protection (NJDEP), the National Oceanic and Atmospheric Administration (NOAA), and the United States Fish and Wildlife Service (USFWS) on voluntary NRD settlements that led to groundbreaking legal settlements to remove numerous low head dams on the Raritan and Millstone Rivers to restore historically significant migratory fish spawning runs. As the technical Project Agent, he planned, permitted, and successfully managed the removal of the Calco Dam, the Robert Street Dam, and the Nevius Street Dam on the Raritan River between 2008-2013, and the removal of the Weston Mill Dam on the Millstone River in 2017, along with leading the archaeological investigation of the former historic Weston Mill in Franklin Township. He is currently planning the removal of the last dam on the main stem of the Raritan River that is impeding migratory fish passage.
