Additionally, the depths <br /> and timing will be selected to maximize the effective collection of soil gas concentrations. <br /> 3.1 RAINFALL <br /> Sampling events will consider sampling after dry weather so that a maximum soil gas <br /> concentration will be represented. If a significant rainfall event of greater that 0.5 inches <br /> occurs, sampling should not be conducted for at least 5 days. <br />
