In the study of sediment pollution on and near a construction site, it is necessary to remember that sediment movement and deposition are part of the natural environment before the intervention of construction. As with many hydrologic problems, most sedimentation problems have visual impacts for relatively short periods, because they are rainstorm-related. Perhaps the most serious sedimentation problem is general deterioration of the total environment, a condition usually not recognized by the public. This research presents an analytical evaluation of five construction sites. The analytical framework categorized the life cycle of construction sites into three stages in order to facilitate a sampling method; these are phase one- the beginning; phase two- the middle and phase three- the end. Each stage generates pollution due to the construction materials used. Soil samples were collected from the construction sites at different stages of construction procedures at strategic locations on the site within two days after a rainfall event. The soil samples were then analyzed to determine how much of the construction materials, (i.e., pollutants), mica, bitumen and paint each contained. The primary objective of the research is assessing how much of these construction materials, pollutants, remain on the sites after construction activities one year later. The results from the construction sites indicate integration of runoff processes and sedimentary pollution, which enhance the determination that; sediments from construction sites were sources of pollution to watersheds. In addition, the (pollutants) mica, bitumen and paint were present in soil samples from the construction sites during and after construction one year later. The distribution and migration pattern of pollutants diminish from the sources toward the stream outfall.
