The effects of moisture inputs on landfill gas production and composition and leachate characteristics at the Vancouver Landfill Site at Burns Bog

摘要

Infiltration of water into a landfill affects the process of waste decomposition. An analysis of variation in landfill gas production and composition(/100 CH_4, /100CO_2)in response to precipitation variations was carried out at the Vancouver Landfill Site at Burns Bog. Results indicate a direct Relationship between cumulative precipitation 14 days Prior to sampling and CH_4 generation(mean r~2-0.88). This finding suggests that a time lag is in effect, wherein the Moisture acts to enhance CH_4 production.
