Which of the following is a type of stormwater pollution?

Stormwater pollution refers to the contaminants that are washed into stormwater systems during rain or snowmelt events. Sediment is considered a significant type of stormwater pollution because it can originate from various sources, such as construction sites, agricultural lands, and urban areas. When rainwater flows over bare soil or construction sites, it can pick up particles of dirt, sand, and silt, causing them to enter drainage systems and waterways.

When sediment enters water bodies, it can lead to several environmental problems. It can cloud the water, reducing sunlight penetration, which is crucial for aquatic plant life. Additionally, sediment can smother habitats for aquatic organisms, disrupt food chains, and carry with it pollutants like nutrients, pesticides, and heavy metals that adhere to the soil particles. The effects on water quality can be detrimental, leading to issues such as algae blooms and decreased oxygen levels in aquatic systems.

While plastic waste, heavy metals, and microplastics are also concerning pollutants associated with stormwater, sediment stands out as a foundational type of stormwater pollution due to its volume and the variety of impacts it has on aquatic ecosystems.
