The authors investigated distribution of cadmium (Cd) and lead (Pb) in soil profile pits affected by municipal solid wastes in Avu dumpsite in Owerri, Southeastern Nigeria in 2010. Transect soil survey techniquewas used in aligning profile pits for field studies and sampling. Standard procedures were used in digging,describing and sampling from profile pits. Sieved soil samples were subjected to laboratory analyses and datawere analyzed statistically using coefficient of variation measured in percentages. Results showed higher values of % CV in silt and clay contents. Variability of clay increased from dumpsite (CV=43.77 %) to moderately dumped site (CV=62.73%) decreased in slightly dumped side (20.98%). Highest mean values of organic matter(26.8 g/kg) and pH water (5.7) were reported in heavily dumped site. Organic Matter showed very significantpositive relationship with Cd (r = 0.92; p = 0.01) and Pb (r=0.97; P = 0.97). There is need to include more soil attributes; results of which should be subjected to multi-variate techniques for more reliability and confidence especially in field applications
