Construction projects address concerns related to water pollution and runoff by implementing various best management practices (BMPs) such as sediment and erosion control measures, stormwater management systems, and proper handling of construction materials. These measures help to prevent soil erosion, minimize the transport of pollutants into water bodies, and reduce the impact of construction activities on the environment. Additionally, construction projects may also be required to obtain permits and comply with regulations that aim to protect water quality and prevent pollution.
