DIRT Dataset – Natural Gas and Telecommunications Totals
Tables 8 and 9 provide specific information on the dataset used for this analysis. “% of Total-All” means the percentage shown includes “unknown” values in the denominator. “% of Total-Known” means “unknown” responses are subtracted from the denominator, which causes the resulting percentage to be higher. A similar approach will be applied to the analyses of other DIRT data fields within this section.

Natural gas and telecom both self-report the majority of their damages, followed by excavators and then locators. Excavators make up a significantly larger percentage of telecommunications event sources when compared to natural gas. The DQI for telecommunications reports are appreciably lower than that of natural gas.
