Sarah Chudnovsky of Shillington, Pennsylvania spent a week testing water in the Schuylkill River as part of the Schuylkill River Sojourn in June. More than 200 people paddled up to 112 miles during the Schuylkill River Sojourn, which spans from Schuylkill Haven to Philadelphia. Chudnovsky’s journey was possible thanks to the Schuylkill Action Network, which provided her with equipment and a scholarship for this, its Sojourn Steward program. The SAN has put Chudnovsky’s discoveries to use by uploading them to the GLOBE program. This will allow users around the world to compare her data with their own and those of others.
