JMS Project Manager and Professional Geologist Tim Dempsey recently spoke with an AP Environmental Science Class at Great Oaks Legacy Charter School in Newark about environmental consulting. Tim led off the discussion with the high school seniors about how the industrialization of cities such as Newark left a legacy of contamination, which led to environmental regulations being developed in the 1970’s. Tim described the various stages of investigation and remediation to the class using the NJDEP’s stages of Preliminary Assessment, Site Investigation, Remedial Investigation, and Remedial Action. Examples of aerial photography and Sanborn maps were shown to the students, as well as photographs of site features such as underground storage tanks (USTs) being removed from the ground. Tim also presented a site conceptual model for a drycleaner site, and how a neighbor’s potable well might be affected. Different types and degrees of contamination due to chemicals such as PCBs and VOCs were discussed, as well as metals and historic fill contaminants. The students were receptive and had great questions, bringing up issues such as responsible parties and environmental insurance. Last, Tim gave examples of some skills that are important in the industry, such as note-taking skills, technical writing, and working with subcontractors, clients and communities. JMS wishes the best of luck to the AP Environmental Science class and the rest of the Class of 2018 at Great Oaks Legacy Charter School!
