All About Arsenic

Embedding science into school curricula to drive real-world impact

Naturally-occurring drinking water contaminants like arsenic pose serious long-term health risks, yet many communities lack affordable and accessible testing opportunities. Together with researchers, educators, and students, I coordinated a citizen science project around well water testing and data analysis, building it into middle and high school curricula in Maine and New Hampshire. The thousands of free samples collected helped community members learn about their drinking water and take steps to improve its quality. The project also increased data literacy and sparked community-driven advocacy efforts to increase access to safe drinking water.

Outcomes/Impact

• Students collected 3,070 drinking water samples.

• The data collected by students more than doubled the information available to public health agencies across Maine and New Hampshire.

• Pilot surveys showed participants began mitigating arsenic and other toxic metals exposure.

• Students testified in the Maine State Legislature, helping pass LD1891 / HP 1401, providing grants for safe drinking water.
