Construction sites are found both within urban and rural areas, often in the close proximity of homes. Due to their proximity to homes and the materials used,construction sites may generate home pollution. This involves air, water, soil, and/or noise pollution. Additionally, construction work may reveal existing subsurface pollution. In such situation, construction work is stopped and costly remediation is needed. Thus, construction work may generate construction pollution problems affecting both homeowners and construction site owners. Moreover, construction workers (especially in the past) may be exposed to pollution. These aspects will be discussed in more details below, along with tips and measures to prevent and face pollution, as well as to recover the costs. If you live in a home close to a construction site (i.e., within 1 block or less) you may face the following type of pollution:

  • Air pollution – the air you breathe may be polluted due to 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), PAHsbound to particulate matter, VOCs(volatile organic compounds), asbestos, gases such ascarbon monoxide, carbon dioxide, andnitrogen 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 bydeposition 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.

 Construction pollution involves the following main types of construction work:

1. Building construction pollution – represents the generation of construction contamination at sites where buildings are constructed which may involve also a demolition phase (if the construction site has an existing building)

2. Road construction pollution – represents the generation of construction contamination at sites where roads are built. In both types of construction work Diesel is responsible for emissions of carbon monoxide, hydrocarbons, nitrogen oxides, PM and carbon dioxide.

The hydrogen technology we use creates a significant reduction in HARMFULL greenhouse gas emissions, CO2,NOx,HC,SO2,NO,PM,VOC,CH4,SF6, and PFC).

Therefore creating less damage to the population and the Environment
