It is important to test the soil before construction is started, as this helps prevent the soil from being negatively affected. The presence of pollutants in the soil can lead to negative human health outcomes. Soil testing is also an accurate way to assess whether a site has enough usable dirt for construction.
The most common cause of polluted soils in North America is improper or inadequate disposal of waste materials from construction sites and factories, agricultural sources that have been using toxic pesticides, and residential lawns that have been treated with fertilizers and pesticides.
Soil testing should be done prior to any construction project because it may provide valuable information about how pollution will be affecting people's health during their lifetime.
