Construction activities play a vital role in economic development and infrastructure growth, but they also pose significant environmental risks if not properly managed. One of the most prominent risks is air pollution caused by dust, particulate matter, and emissions from construction machinery and vehicles. Activities such as excavation, demolition, cement mixing, and transportation of materials release fine particles into the atmosphere, which can degrade air quality and affect nearby communities. Prolonged exposure to such pollutants is associated with respiratory and cardiovascular problems, as highlighted by agencies like the World Health Organization. Another major environmental risk is noise pollution generated by heavy equipment, drilling, blasting, and material handling. Continuous high noise levels disturb human settlements, reduce work efficiency, and negatively impact wildlife by disrupting their natural behavior and breeding patterns. In urban areas, excessive construction noise often leads to stress, sleep disorders, and reduced quality of life among residents. Water pollution is also a serious concern in construction projects. Runoff from construction sites often carries sediments, chemicals, oils, and construction debris into nearby water bodies. Improper disposal of wastewater from concrete mixing, washing of equipment, and site cleaning can contaminate rivers, lakes, and groundwater. Such contamination reduces water quality, harms aquatic life, and increases treatment
