What soil gas survey design issue impacts results?
Undersampling! In an effort to save money, undersampling during the site characterization part of the environmental investigation may occur. In other words, not enough samples are collected to characterize the site properly. Questions pertaining to the subsurface impact are inadequately answered, leading to uncertainty, an unhappy client, and additional regulator scrutiny. The next phase is to expand the soil gas survey, which increases the overall project cost, and adds significant time to the site investigation for all parties involved. Undersampling should be avoided.
