    The RemMetrik Process of Environmental Remediation

    Presented By:

    Steven E. Panter, CGWP, PG (NY)

    Abstract: A remediation process that a employs improved quantitative method(s) of estimating of the volume and/or mass of contaminant in the subsurface, removal and or in situ degradation of the contamination using subsurface pulsing treatment (“SPT”) technology, and evaluation of the degree of remediation by re-applying the quantitative contaminant evaluation methods. The process uses SPT technology with the addition of a vacuum or sub-atmospheric pressure to an extraction well in order to create a push-pull effect to remove free contaminant or residual in conjunction with the pressure wave driving force created in the excitation or excitation well. The process can quantitatively measure the amount of residual contaminant, which up until now has not been possible or tractable using in situ methods, as well as measure the amount of residual that can be removed by SPT.

    *Bio: Steven Panter is an environmental consultant and professional geologist in New York with over 40 years of experience investigating and remediating contaminated sites in the NY/NJ metropolitan area. For approximately the past 20 years his work has focused mainly on Brownfield sites in and around New York City. His work focuses on soil and groundwater investigation and remediation; he also works on environmental forensics analysis.

    He brings statistical and graphical analysis to his work to help understand the distribution and behavior of contamination and to support conceptual models to direct and focus remediation. Using statistical analysis, he is able to view data from multiple perspectives and test different hypotheses. He has extensive site investigation and remediation experience and has cleaned up sites having a variety of contaminant issues and has developed a unique in situ remediation process, RemMetrik.  Email:

    The LIAPG Museum of Natural History
    Guided Tour Through the Hall of Gems and Minerals is planned for Sunday, July 28, 2024!!!

    • You will register for FREE to be in a LIAPG Member-group guided by a docent.
    • You will need to purchase your own admission ticket in advance, which should be for a 10 AM entry. We are doing this because some people may want to purchase tickets that allow for admission to special exhibitions after the tour, and if you are a resident of NY, NJ or CT, you can pay what you want and have to do that registration yourself. Your ticket will get you access to all the permanent halls of the museum.
    • These tickets can sell out quickly so it would be appropriate to get one at least a week in advance. These tickets can be purchased using the link below:
    • At 9:45 AM, we will meet at the new Gilder Center entrance, as it’s super cool and it’s closer to the Gems and Minerals exhibit than the other entrances. The entrance is located at 415 Columbus Ave at the intersection of Columbus Avenue and W 79th Street.  Here is a picture:

      • Weather permitting, we plan on having a bring your own lunch/picnic in Central Park after the tour!

      LIAPG 2024 Summer Canoe/Kayak Trip & Picnic 

      Saturday, August 17, 2024

      This is a 5.5-mile, easy paddle on the beautiful Nissequogue River riding the outgoing tide that takes approximately 2.5 hours.  We will meet/park our cars at Nissequogue River State Park where the bus will take our group to put in at Paul Given County Park ("The Bull").  The start time is TBD. The trip ends at Nissequogue River State Park where we will enjoy a catered barbeque/picnic.

      Not into the water? 

      You absolutely are welcome to just come for the picnic!

      Registration will open closer to the event date.
