Since 2004, the SPLASH Delaware River Floating Classroom has delighted school-age and adult groups with engaging environmental educational lessons with the Delaware River as the central focus. Students learn hands-on about river critters, also known as macroinvertebrates; the delicate chemical balance of our river needed to sustain life; and the importance of the river’s food web through freshwater phytoplankton. Students gain a greater sense of the Delaware River and meaningful ways to continue to protect the beautiful Delaware River, source of drinking water for 15 million people. Based in Lambertville, SPLASH is a volunteer-driven non-profit serving groups from Mercer, Hunterdon and Bucks Counties. In addition, since 2018 a dedicated team of Citizen Scientists monitor 2 tributaries and the mainstem Delaware River, in Lambertville.
