Abstract

Sanitary landfilling is one of the initiatives done by the local government in waste management. The waste from this site contains heavy metals that can cause soil contamination. Heavy metal concentration in landfill soil in San Mateo Sanitary Landfill was determined through scanning electron microscope – electron dispersive xray (SEM-EDX) technique. Acquired values were then compared to standard Earth’s crust value. Results show that the values of Ca, Mg, and K are lower compared to the standard while Al is relatively high. This is attributed to the oxisol soil classification of the chosen site. An enrichment factor pollution index was used to determine elemental enrichment in the soil with respect to the base line concentration. Results for Ca (0.064-0.785), Mg (0.027-0.729), and K (0.060-0.601) suggest that the metals detected are due to natural occurrences. Iron enrichment factor corresponding to a range of 1.458 – 5.233, with an average value of 2.545 indicate that there were anthropogenic contributions. Anthropogenic sources of iron in the landfill is attributed to waste coming from industrial facilities such as steel industries.
