After the first federal regulations on coal ash, utility companies were required to conduct groundwater testing at sites around their property and post the data by 2018. Throughout the following year, nonprofits such as Environmental Integrity Project collected the data from 265 sites. This map shows the 91 percent of plants polluting groundwater. The yellow pins show an exceedance of only one digit. The orange pins show double digits ranging from (x10) to (x99) federal standards, and 205 locations are polluting chemicals in the double digits. The red pins shows triple digits ranging from (x100) to (x532) the safe levels according to EPA. Twenty-five locations are polluting chemicals over a hundred times the safe amount.
