Students from Trenton Elementary School in Trenton, Maine

Caption

These students from Trenton Elementary School in Trenton, Maine, are among those participating in a program to teach data literacy to Maine and New Hampshire students by analyzing data on arsenic in well water collected from their homes. The program found that 25 percent of samples exceed the New Hampshire maximum safety level of 5 parts per billion (ppb) and 15 percent exceed the U.S. Environmental Protection Agency (EPA) maximum safety level of 10 ppb. The program also found that 62 percent of homeowners in the two states hadn't had their well water tested or didn't know if it had been tested.
