SCS Webinar: Black Goo, Pluggage, and Scaling in Landfill Gas and Leachate Infrastructure

May 19, 2022 @ 2:00 pm - 3:00 pm



Prresented Live on Thursday, May 19, 2022
2:00 pm Eastern Time for 1 hour


Landfills across the country are experiencing a trend ─ black goo, pluggage, and scaling in their leachate and gas collection systems. These organic and inorganic deposits are difficult to treat once they’ve seeped into liquid and GCCS systems, clogging equipment and pipes, and impacting the extraction of liquids and landfill gas.

Our panelists this month discuss best practices for identifying, treating, and possibly even preventing these chemical deposits before and after they occur within your infrastructure. We’ll also include what landfill field operations can do to identify and treat conditions that appear symptomatic of possible future issues.

No one has all the answers ─ each site’s conditions are unique. Our team of engineers, scientists, and landfill-landfill gas operations experts will provide a comprehensive discussion in May of what we are seeing and piloting in the field.

  • Samuel Cooke, PE, Chemical Engineering, Leachate & Industrial Wastewater Treatment
  • Brian Kelley, Field Services, LFG Control, Recovery, Emissions
  • Nathan Hamm, PE, Liquids Management, Industrial Wastewater & Leachate Treatment
  • Marc Lefebvre, PE, Chemical Engineering, Industrial Wastewater Treatment Studies & Designs
  • Mark Pearson, PE, Environmental Engineering, Water & Wastewater Treatment Plant Process Designs

As with all SCS Client Webinars, we’re here to answer your questions throughout the forum and afterward. Using case studies and field experience, our panelists take us through the science, environmental conditions, and technical considerations to prevent or treat this emerging challenge before it gets costly.

This educational, non-commercial webinar with a Q&A forum throughout is free and open to all who want to learn more about landfill pluggage concerns and preventative treatments to consider. We recommend this month’s discussion for landfill owners/operators, landfill gas technicians, environmental engineers, and environmental agency staff. A Certificate of Attendance is available on request following the live session.



The University of Wisconsin – Madison is currently studying landfill black goo under an EREF grant. With permission of the landfill owner/operator the research team is requesting 1 liter samples of goo be sent to them. You may want to send more than one sample; often the goo characteristics vary across a landfill or cells. Please send samples with a point of contact and identifiers to:

Mr. Xiaodong Wang
2241 Engineering Hall
1415 Engineering Drive
Madison, WI 53706

If your local university is sponsoring a study, the Wisconsin researchers look forward to collaborating with your team.
