LANDFILL COVER INTEGRITY STUDIES

A professional tool for the professional landfill operator.

According to US EPA 40 CFR Part 258, Subpart F, landfill site owners/operators are required to monitor and maintain the landfill once it is closed, and throughout the post-closure period.  This includes inspecting the effectiveness of the final cover system - an engineered solution generally consisting of soil and a vegetative cover.   The purpose of the final cover system is to minimize water infiltration and limit the exposure of waste and harmful gases generated from the waste decomposition process.

 

The Sniffer team provides aerial and manual inspection services to monitor the integrity of the landfill cover system.  Sniffer's software solution provides actionable information to remedy, with analytics benefiting operations.  

Our Methodical Approach

 

Our technicians are properly trained on the specifics of the regulatory requirements. These requirements include calibration of the equipment, monitoring weather conditions, equipment set-up and utilization, walking path requirements, identification of additional areas to inspect, reporting methods, and others. 

 

Technicians utilize Sniffer's designed apps on their mobile devices to record their walking path and to record locations where exceedances (methane concentrations above the prescribed threshold) are found.  Details of the location and the cause of the exceedances, along with additional information are recorded onsite at the location when observed.

Detailed inspection reports are provided to customers promptly at the end of each daily inspection.  The report contains:

 

  • Methane concentration (PPM)

  • GPS coordinates with location details (e.g. distance to gas well)

  • Site map with pinned locations where issues were found

  • Walking path 

  • Potential cause and/or suggested corrective action

  • Photograph of exceedance location

  • Additional notes

  • Detector calibration report(s) & calibration gas certs

 

At the end of the 30-day inspection, a formal report is provided for regulatory compliance purposes.  Learn more how our reports and designed to 'Inform for Action'.

Customers may also license Sniffer's Field Ops™ (SFO) software solution.  The app - available for mobile devices, provides real-time feedback of our technician's inspection activities.  Automated email alerts notify customers when exceedances are found by our technicians with a link to view details from a mobile device.  SFO was designed to provide instant information to customers of found exceedances, allowing an opportunity to quickly remediate the location while technicians are onsite.
