A case study regarding the operations of a woodwaste landfill in northern New Brunswick

Abstract

The following report reviews the operations of a woodwaste landfill in Northern New Brunswick to determine if changes can be implemented to improve the quantity and quality of leachate produced by this site. The study was undertaken after environmental monitoring results showed increased levels of organic matter within the wastewater in comparison to previous years. After reviewing the current conditions at the landfill it was observed that a malfunctioning leachate collection system was allowing infiltration of leachate into the surrounding area, and after completing a hydrological survey it was determined that with the current conditions that at full capacity the landfill would generate approximately 135 000 m3 of wastewater annually. Since organic content within the wastewater is so high, experiments in wastewater treatment using chemical oxidation and traditional mechanical aeration were performed with the objective of developing a practical, cost effective wastewater treatment system.
