Answer:
Water pollution - the surface water runoff and the groundwater close to a construction site become polluted with various materials used in the construction work. ... In fact, both groundwaters below your home and surface runoff close to your home may constitute a source of pollution emanating from the construction sites.

the construction work. Apart from the noise, poor air quality is the most immediate pollution effect you may experience from a construction site. This means that airborne contaminants including contaminated particulate matter and volatile compounds are spreading around (mostly carried by wind) in the surrounding neighborhood (the main wind direction will influence the area most affected by air pollution around a construction site). Contaminants spreading around in air can travel large distances in a short time. The main construction contaminants that spread around by wind include PM10 (particulate matter with a diameter less than 10 microns generating polluted dust), PAHs bound to particulate matter, VOCs (volatile organic compounds), asbestos, gases such as carbon monoxide, carbon dioxide, and nitrogen oxides.
Water pollution - the surface water runoff and the groundwater close to a construction site become polluted with various materials used in the construction work. As described for air pollution above, the following construction contaminants can pollute the water: VOCs, paints, glues, diesel, oils, other toxic chemicals, and cement. The immediate effect is creating turbidity in the runoff water and affected surface and groundwater (since some of the runoff water may infiltrate in the subsurface reaching the groundwater. In fact, both groundwaters below your home and surface runoff close to your home may constitute a source of pollution emanating from the construction sites. Domestic animals and pets may drink contaminated water and soil may become contaminated too. Additionally, once the groundwater below your home becomes contaminated, it may affect you in the following ways: through direct consumption if you use water from a property well, and indirectly by affecting the quality of your indoor air (vapor intrusion of the volatile contaminants from water). Overall, water pollution from construction sites is underestimated and has potential to generate severe environmental problems.
Soil pollution - soil at and around a construction site may become contaminated due to air transport followed by deposition of construction contaminants (listed at air pollution) as well as water runoff of construction contaminants (as listed for water pollution). Soil may constitute a sink for pollutants and some of those may accumulate in soil and persist over longer periods of time (e.g., PAHs).
Noise pollution - noise is usually associated with construction work although modern preventive measures may substantially reduce the amount of noise (in the neighboring community). Noise may adversely affect your health, including effects such as stress, sleep disturbance, high blood pressure and even hearing loss.
