What is a common source of pollution on construction sites?

Soil erosion from land-disturbing activities is a prevalent source of pollution on construction sites because construction often involves clearing vegetation, grading, and excavating soil. These activities expose bare soil to the elements, making it susceptible to erosion by wind and water. When soil erodes, it can wash into nearby water bodies, carrying with it various pollutants such as sediment, nutrients, and organic materials. This increase in sedimentation can degrade water quality, harm aquatic habitat, and contribute to the deterioration of water resources.

The management of soil erosion is critical in a Storm Water Pollution Prevention Plan (SWPPP) and is often addressed by employing erosion and sediment control measures like silt fences, sediment basins, and matting. The focus is on stabilizing disturbed areas and preventing sediment-laden runoff from leaving the construction site.

Other options may also be sources of pollution, but they are not as directly related to the typical activities and impacts of construction sites. Excessive watering of plants might lead to localized flooding or increased runoff, but it is not a primary concern compared to erosion. Runoff from agricultural fields can introduce pollutants, but it is external to the construction site itself. Urban waste from neighboring areas contributes to overall pollution but does not typically stem from the
