    This is the seventh in the 2021 Monthly Online Presentation Series!

    Presented By:

    Dr. Alan I. Benimoff

     Department of Engineering and Environmental Science

    College of Staten Island/CUNY


    The interaction between geology and culture is represented on Staten Island by building stone, monuments, and gravestones. The corridors of the Staten Island Mall are tiled with a 160 million year old Comblanchien limestone that contains fossils of bivalves, corals and gastropods. In November of 2003 the mall was opened early so that “general education” students from the College of Staten Island could study these fossils. Since then, signage identifying select fossils has been placed around the mall directing observers to those fossils. We have developed a Staten Island mall exercise for our general education students. A  nearby public school revealed an internal wall of limestone containing fossils of brachiopods, bryozoans and corals. Another school has internal walls that contain limestone exhibiting stylolites. Many of the older gravestones in the Moravian Cemetery consist of marbles, and sandstones. One of the more extraordinary gravestones, for General Stephen Weed of civil war fame, is  constructed of a limestone containing crinoid fossils. Other examples include a church exterior constructed from Staten Island Serpentinite and walls constructed of Palisades diabase, In addition, clay from Staten Island was utilized for bricks. Iron ore and diabase were quarried and asbestos was mined. It is noted that straw and rose colored “amianthus” was discovered on Staten Island around 1818. According to Frondel (1988) this probably led to the first large-scale asbestos mining operation in the United States.

    Registration opens on 1 July, watch for the email announcement.

    The presentation will be followed by a geologic trivia question and answer activity for those who would like to participate!

    *Bio: Dr. Alan Benimoff studies the petrogenesis of igneous, sedimentary and contact metamorphic rocks of the Newark Basin and the Staten Island Serpentinite. He is interested in studying chemical gradients in coexisting Basaltic and Trondhjemitic Magmas What are the relative diffusivities of these ions in the coexisting melts? Why didn't the two melts physically mix? Using a GIS(Geographic Information System) he studies environmental problems on Staten Island and elsewhere. He has published articles in Nature, the American Mineralogist, the Canadian Mineralogist, Journal of Geology and Geological Society of America Abstracts with Programs . In 2004 he discovered a new Mineral called parvo-mangano-edenite. He was featured on the National Geographic Channel’s  Known Universe in an episode entitled “Cosmic Fury”. Dr. Benimoff is a public access producer and host for the Staten Island Community Television program Geology Forum. He teaches Soils and Geohydrology and Earth Science in the Masters Program in Environmental Science and Physical Geology, Historical Geology and Environmental Geology. Professor Benimoff has taught Material Science at Cooper Union.

    This is the LIAPG 2021 Monthly Online Presentation Series!

    Presented By:

    Eliot Cooper

    Cascade Environmental, LLC


    Chlorinated solvent source areas pose some of the biggest challenges to remediation practitioners. At most sites, the contaminant mass overwhelms in situ chemical oxidation (ISCO) and in situ bioremediation (ISB), and requires additional remedial measures before closure can be achieved.

    Consultants are left with two remaining options for these sites: thermal remediation and injection of eZVI (emulsified zero valent iron).

    In this webinar, remediation expert Eliot Cooper will address the latter option. He’ll explain…

    • How the chemistry was developed by NASA and how it works
    • How it can be optimized through high resolution designs
    • Where it can be applied
    • Design considerations including dosing and volumes
    • Delivery approaches
    • Associated costs

    *Bio: Eliot Cooper is the Vice President of Technology and Business Development. In this role, he helps clients design efficient and cost-effective remedies using high resolution site characterization (HRSC) and a vast array of remediation options. His specialty is finding the right combination of tools and technologies for complex sites, and ensuring every step of the remediation process is optimized to achieve results.

    Eliot draws on a career that spans more than 30 years in the environmental remediation industry and includes hundreds of projects nationwide. He’s remediated sites that involved hex chrome, fuel spills, and chlorinated solvents. He specializes in injected remedy delivery, remediation design support, characterization of VOCs, and tackling complex sites by combining multiple remediation technologies.

    Eliot previously served at the Environmental Protection Agency in both air pollution and hazardous waste management programs, as well as in the private sector providing thermal combustion and in situ remediation field services. Eliot now leads Cascade's in situ remediation solutions team to evaluate available technologies to meet client goals, provide advanced delivery techniques, and ensure HRSC results in actionable solutions.
