Unguarded waste disposal with its concomitant environmental degradation has being a global concern in recent times. Cases of waste disposal from paint manufacturing outfits were not left out in his issue. Study on the assessment of the contaminated soil by waste from paint manufacturing activities has been carried out in a typical Niger delta soil. The study area was divided into four sampling sections, wherein five samples were randomly taken from each segment, making a total of twenty soil samples. The sampling sites were designated as SS2, SS3, SS4, and SS5 which represented; the main discharge point, former discharge point which was abandoned five years ago, main gate and spill points respectively the control site was also located, and five soil samples were randomly collected therein. Each sample was analyzed for Pb, Zn, Cu, Cr, Ni, Cd, Mn and As using standard methods. The average Heavy metal concentration values in the study sites were apparently higher than the control site. However, the sampling sites were impacted at varying levels as follows SS2> SS4> SS5> SS3. The level of impact of Cu, As, Cr, Ni, Pb and Mn in the entire study area was quantified in percentage and presented in descending order as 82, 62, 52, 39, 24 and 12% respectively. Elevation of the study sites and Spatial Distribution of the metals were studied with the aid of GPS and the data produced with ARC GIS. The Distribution of the metals were largely affected by the elevation of various sampling sites. Most metals were leached to lower elevations despite the proximity of the sites to the source of discharge. There was low Pollution index (PI) of between 0.01-0.068 for Cu and Zn in all the study sites whereas high PI of between 21.5-12.5 was recorded for Mn in SS3, SS4 and SS5. From the index standards, the soil was contaminated, on the average with Cr, Cu, Zn, As, Ni and Pb at low level and moderately contaminated with Mn and Cd. On the bivariate analysis, there was strong correlation between Cu and Pb, Zn with As and Cr, Ni with Cr and As. In the principal component analysis (PAC), As and Cu have the highest variation values of 0.979 for As and 0.987 Cu in components 1 and 2 respectively and these two components control 91.004% of the total variation. By the analysis of variance, there was no significant difference between heavy metals in the sampling sites, however, the Post-Hoc analysis confirmed significant difference in the metal discharge between (SS1), and SS2, SS3 SS4 and SS5 respectively, affirming that the discharge from the paint manufacturing outfits essentially contributed to the prevailing heavy metal concentrations in the sites.
