Emma Pierotti is the water quality coordinator for the Saco River Corridor Commission. In this position she takes water samples from test sites along the Saco River, transports equipment to testing sites, and records and uploads data at the SRCC office.
Emma has lived in the area since 2010, and she currently stays on her family’s farm in East Baldwin. Soon after moving to Maine, she was motivated to start a career in protecting and conserving the state’s natural resources, and joined the SRCC in 2023. While quite new to the field, Emma cares greatly for the work the SRCC does and hopes to continue working with them in the future. As she works with the SRCC, Emma is also studying to earn her environmental science degree at the University of Southern Maine.
