Control of gas from landfills and/or marsh areas
- E.H. Hanson Engineering Group Ltd., Delta, British Columbia (Canada)
Landfills are the most well known source of methane formed by decomposition of organic material, but the authors have found that marsh gas generated by peat deposits also contain large quantities of methane and often become a formidable hazard. This is particularly true when small amounts of refuse or ground wood fill (hog fuel) has been placed on the marsh area to raise the ground elevation. It is well known that there is a natural propensity for methane generation and explosion from municipal solid waste landfills and marshlands. Despite this fact, in the Vancouver area, large, high value land development projects are taking place adjacent to methane generation areas and directly upon them. This is due to rapid growth and the consequent high demand for serviced building lots. Consequently, it became necessary to develop soils gas eradication systems which totally eliminate any danger of methane accumulation in buildings, in waste water and land drainage piping, and in underground electrical and telephone conduits. This was accomplished for a high caliber industrial/commercial site in Coquitlam, B.C. known as Pacific Reach Business Park. The site consists of about 180 acres and is underlain by peat and silt. It then became the recipient of municipal solid waste and ground wood waste (hog fuel), all of which produce methane. Finally it was topped with clay and dredged sand from the Fraser River. The biodegradation of carbon from the refuse plus the cellulose from the wood waste generated high volumes of methane. All of the underground municipal, telephone, and electrical conduits are protected from methane intrusion by a city-owned methane eradication system funded by the developer. The buildings each have built-in, custom designed, protection systems. Development is about 75% completed.
