A sanitary landfill was simulated by placing “refuse” between two layers of soil in a temperature controlled cylinder. Canine nutriment was used to simulate the refuse. Distilled water was added and withdrawn at two week intervals to leach out the pollutants. The simulated landfill was maintained at 30°C, at 23°C, and at 15°C. The leach water was periodically analyzed for Chemical Oxygen Demand (COD), pH, Phenolphthalein acidity and total residue. In addition the soil pH was determined. In general, the analytical data for the leach water was found to depend on the temperature of the landfill. The curves of pH versus time of both the leach water and soil has approximate sinusoidal wave shapes with the initial slope usually negative. The pH curves were consistent with the two stage decomposition theory of the refuse in the landfill.
