Minimizing Pollution in Construction: Adopting Preventive Measures as a LEED Green Associate
Construction projects can significantly contribute to airborne dust pollution, a concern that is often overlooked. However, by implementing a series of preventive measures, construction sites can effectively reduce airborne dust levels and limit particulate air pollution.
Airborne dust consists of tiny particles that become suspended in the air due to activities like demolition, excavation, vehicle traffic on unpaved surfaces, and wind blowing over disturbed soil. These particles can have detrimental effects on the environment and public health.
Prevention activities during construction include covering or wetting the exposed soil and stockpiles, using water sprays or misters to suppress the dust, installing wind fences or barriers around the site, applying mulch, straw, or vegetation to stabilize the soil, sweeping or vacuuming the paved areas and roads, limiting the speed and frequency of vehicles, using low-emission or electric vehicles and equipment, and implementing a dust control plan and monitoring the dust levels.
Some best practices to minimize dust generation include phasing construction to limit the amount of exposed soil at any given time, stabilizing disturbed areas with mulch, vegetation, or other coverings as soon as possible, regularly wetting down surfaces using water trucks or sprinklers, washing vehicles before they leave the site to avoid tracking out dirt, properly covering and securing loads during transport, and paving, applying water, or using dust suppressants on haul roads.
These preventive measures not only help in maintaining a cleaner environment but also contribute to the mitigation of climate change. Airborne dust can affect the climate by absorbing or reflecting solar radiation, altering cloud formation and precipitation patterns, and influencing the carbon cycle.
It's worth noting that terms like B. Blackwater, which refers to wastewater containing fecal matter, and A. Infiltration, which refers to air leakage into buildings, are not directly tied to construction activities. Similarly, high-reflectance materials, while helpful in reducing the heat island effect, are not a pollutant that prevention activities aim to limit.
For those preparing for the USGBC LEED Green Associate exam, the USGBC LEED Green Associate certification exam practice question and answer (Q&A) dump is available free online. This resource can be beneficial in passing the exam and earning the USGBC LEED Green Associate certification.
In conclusion, by adopting these preventive measures, construction projects can not only ensure a cleaner and healthier environment but also contribute to the global fight against climate change.
