BRIDGETON, MO (KTVI)-- Thursday was the deadline for submission of expanded air sampling data from the Bridgeton Landfill.

It should help determine the movement of the three year old underground fire.

Last month, Missouri Attorney General Chris Koster asked for more carbon monoxide sampling in the North Quarry of the Bridgeton Landfill.  That's the area closest to the radiological material buried in the West Lake Landfill.

Data collected over the last month reflect samples from 25 gas extraction wells.  They are represented by the purple circles on a map.

In a statement from Republic Services, a spokesperson says "the results from the month of January confirm that all wells in the North Quarry register below the lowest possible reporting indicators for CO and confirm previous assessments that the subsurface smoldering event has not impacted the North Quarry, which is the area closest in proximity to the radiological materials in the adjacent West Lake Landfill."

Spontaneous combustion will produce excessive amounts of Carbon Monoxide (CO) and other trace toxic gases.  And that could indicate the fire is moving closer to West Lake.

The attorney general's response to the report was issued in this statement.

"Today’s data submission was made pursuant to the January 17, 2014 agreement between the Attorney General's Office and Republic Services requiring Republic to provide comprehensive carbon monoxide data for all active gas extraction wells located in the north quarry, including the "neck" area of the Bridgeton Landfill. Access to this data is critical to get the most accurate picture of the underground fire. We look to the Missouri Department of Natural Resources and local first responders to interpret the data."

Republic Services has agreed to provide two additional CO reports.  They are due in the attorney general's office on April 20th and June 20th.

Sunday's smoky surface fire caused a lot of concern. That event and the CO data will be included in the discussion at a Westlake community meeting Thursday at 6:30 p.m.
