Landfill Monitoring with iDataCollect Software

Landfill and Wellfield Monitoring at the Gulf Coast Landfill in Fort Myers

Waste Management Closed Sites Group of Marietta, Georgia selected Weston & Sampson to provide engineering, monitoring, and reporting services associated with the monitoring of the Gulf Coast Landfill in Fort Myers, Florida. These services are part of the landfill’s requirements for monitoring landfill gas migration and production at the landfill.

Landfill gas monitoring is conducted at the landfill to assess if landfill gas is migrating beyond the landfill and/or the property’s boundaries. This involves the monitoring of a series of gas monitoring wells located around the perimeter of the landfill. The constituents that are monitored include methane, oxygen, hydrogen sulfide, and non-methane volatile organics that make up the landfill gas. These constituents are reported to the Florida Department of Environmental Protection (FDEP). This monitoring is performed using Landtec gas monitoring equipment.

Weston & Sampson also performs gas monitoring for the active landfill gas collection system at each individual gas extraction wellhead. Monitoring the gas at these locations allows Weston & Sampson to actively evaluate the concentrations of methane and oxygen at the wellheads to make sure that the optimum mixture of methane and oxygen allows for a clean burn of the landfill gas at the destruction facility. The destruction facility at the landfill consists of an enclosed flare that burns the gas at a series of flare heads located within the enclosed flare. Having an optimum mixture of gas allows the enclosed flare to burn the gas and still meet its regulatory air permit requirements.

At each well, Weston & Sampson reads the static pressure, gas flow rate, balance gas, oxygen and methane at the wellhead using the Landtec equipment. Once the proper readings from each well are obtained, it is determined whether or not the wellhead needs to be tuned to adjust the percentage of methane that each well produces.

By maintaining the optimum percentage of methane from each well, Weston & Sampson can make sure that the landfill gas enclosed flare is fed the optimum mixture of gas for the best performance of the equipment.

Weston & Sampson also reports the levels of the landfill gas and its constituents to the FDEP, as required by their solid waste and air permits. Weston & Sampson uses our iDataCollect software to report the results from the monitoring.
